Top radiator hose sliced by top engine cover

[Odysseyman]

Ok so yesterday out in the Vic High Country in our 2016 D4 SDV6 after about 200 km I got a low coolant warning light. We found the top hose neatly sliced open, about 2cm long, by the top engine cover. Has anyone else had this problem??
I’m at our Indie at the moment and they say there is not a top hose anywhere in Aust or UK. Grrrr ! The car was serviced only 2 weeks ago and I have a feeling the top cover wasn’t positioned correctly but in the heat of the moment I was too distracted finding the leak to notice it’s position before I took it off.
So, is this a common problem? Surely not!
And can anyone help with a top hose please?
Cheers
David
PS I’ll post this in the urgent help thread as well.

It’s common

Had the same problem at the Winter Wombat. I think it occurs because somebody does not put the engine cover on properly. I also ground the opening so it could not happen again. I find it hard to believe that they still dont have a top radiator hose in Aus. Thats what they told me in August, then suddenly they found one in Darwin.

[DiscoJeffster]

It’s not because of the cover being incorrectly fitted. It’s because it’s poorly designed without enough clearance to a hose that moves around a bit. The fix is the new iteration hose which has some protection added plus I cut out some of the cover plastic to make more clearance.

[WhiteD3]

Not common I'm sure and never happened to me in mine.

[rocket rod]

I had the same problem up near Broome. I only had gaffer tape to do the repair but it lasted for 200km until I reach town and acquired a hose that fitted. It's a design issue so the easiest thing to do is cut out the cover a bit more so it doesn't happen again. I eventually took it to a dealer and they replaced the hose and did a radiator flush under warranty.

[BobD]

I had the same problem on the GCR road in 2014 but saw it chafing and put some tape around it. I then put some conduit over the offending spot to stop further chafing.

Last year on the GRR I noticed that is was chaffed halfway through while looking under the bonnet at Mitchel Falls. Many repairs since the first time I saw it the conduit was not replaced and this time I didn't notice until it was half way through the pipe. We got one ordered in Kununurra which was delivered to the dealer in Darwin and they replaced it when we reached Darwin.

The new pipe is no better and now has some spit conduit around it and it is checked regularly.

Whilst on the GRR I heard of another D4 that had cut through and had to be towed to Kununurra. I was a bit luckier, just!

[LRD414]

The fix is the new iteration hose which has some protection
The protection sleeve is not at the location where the cut occurs, it's further along away from that elbow.
Sleeve in factory position and my added protection can be seen in the photo below.

Scott

[dirvine]

When mine happened the dealer said that in all probability it was the cover not located and clipped into position. Like Scott I have the latest version of hose and also one of the latest D4's imported into Aus. The dealer showed me how it can happen and although I did not notice the cover not being located properly when the cut occured, I can see how it could happen. Like Scott after the incident I widened the opening, but I am not convinced it was too small in the first place but rather the cover not being properly put back in place.

[BobD]

My cover is always put on the right way. It is pretty hard to get it wrong!

There is a small clearance to the pipe when static but when on corrugations things move and the cover chafes the pipe. Nothing to do with incorrect cover placement or installation.

Will be checking mine tonight

Update: just checked and cover has nearly worn through the hose. There is just not enough clearance and the “protective sleeve” just slides down the hose. The photo is when I’ve moved the sleeve up to stop further chafing. I have just now modified the cover, taped the sleeve in place. I will be ordering a new hose...

Took my cover off years ago, to many things out of view underneath that can cause issues.

Shame me I am not home in Darwin ,I have a full hose set sitting in the shed, the other is with me in the camper in tassie.

hope you find a replacement soon.

Yes but like me you’ve got the more reliable Gen1 2.7 engines [emoji6] becoming more and more a collectors item. This is a 3.0 problem

[letherm]

There was a thread a while back which mentioned this issue. From memory it was sorted in later models so your theory of a badly positioned cover sounds quite plausible.

Ok - I thought they were the same engine just a bigger bore and extra turbo . I assumed the coolant hoses to be the same .

My mistake on reference to the hose kit.

Thanks you all for your replies.
My attention was diverted when my mother in law was admitted to hospital today and things went a bit haywire. Now all under control thankfully.
Looks like I need to call into a dealer and lodge a warranty claim.

This thread makes me chuckle. No, not for the misfortunes of others, but when the D1 facelift was "road tested" (AKA.... Having a jolly old junket down under) in Oz I was told that LR spent some months here on all types of terrain so that things like this could be eliminated before the release. "Built for Aussie conditions" my arse.
That is one of the reasons we unfortunates finished up with the Lifting Dash problem of which apparently were not necessarily covered under Warranty. Improper choice of adhesive was blamed & whoever would have thought the Australian Sun would do such a thing on a semi flat surface behind glass & mostly always in full sun light?

Only some designer burke in the UK is who. Sounds like the hose problem is another one he/she can chalk up as a great success & Blind Freddy could see it was a problem just waiting to let someone down in the outback.

IMHO, what should have happened is what the above owners have done to get them selves out of the brown stuff & just required a bit of imagination in the 'design' Dept.

Right, back to my chuckles & feeling of disbelief.[smilebigeye]

Many thanks to the Forum in flagging this problem. I checked my 2016 D4 this morning and sure enough the top hose has a split in it. Rather than chafing it looks more like its been cut by a knife - not all the way through though. I have wrapped some tape around the cut and booked the car in for a repair under warranty. Ive done 126,000ks and I'm pretty sure that I have already had the top hose replaced at around 70k - same problem I suppose but wasn't aware of the Cover causing the problem and LR didn't say anything.

Read this thread.
Just been out to the garage to check the hose.
2013 D4 SDV6. Coming up to 96k.
There’s a score mark on the top of the hose, obviously from the cover.
Cover in correct position.
I’ve put a bit of rescue tape around the hose for the moment, and some conduit on the offending edge of the cover.
Will be replacing hose to be sure.

[ATH]

Darren (DazzaTd5) did mine when he serviced it for which I thank him. Not something I or most others would have thought about I reckon.
Shows the worth of using an independent who knows the vehicle rather than the stealers who would deny anything like that would ever happen or claim it was "incorrectly refitted"...

Hi Daz,

Do you know if there’s a full replacement kit for all radiator hoses for the D4?

E.g. Britpart do a silicone kit for early model defenders.

Im replacing the top hose cause i have to, but would like to think about replacing all hoses as they’re coming up to 8 years

Just replace the top hose, there are 50 million other hoses and as someone here pointed out recently, hoses in general terms have turned into a 10 years and then some lasting item

[Tankmat]

I had mine replaced under warranty recently, very common problem that is inherent to the engine cover and not its mis-alignment. I cut away ~1 cm from the RHS of the cover adjacent to the hose where it was rubbing then followed Scott’s advise and added rubber hose with super glue. I used the same hose as Scott from Supercheap auto, Codan 3/8” H514 oil cooler/transmission hose which can be purchased by the metre and was a perfect fit. Upon removing the engine plastic cover I noticed it had a fairly sharp lip all the way around and was infact rubbing very slightly at two additional spots. I dremmelled the sharp edge off the entire cover as preventative maintenance.

For people just replacing a damaged hose, if the cover is not trimmed significantly to give the hose more clearance then the new hose will succumb to the same malaise. Adding protection to the cover won't stop a hose chaffing - the hose must never touch the cover.

[PerthDisco]

Told two of my friends with 3.0 engines in Discos to check and one of them was cut half way through the other was untouched.

The cut is at the passenger side of the hose which is not immediately where you think looking at the top. You feel it more than see it.

The clearance around the hose looks more than adequate.

The edge of the plastic cover opening is sharp as a knife.

Checking on my 2.7 and the top hose is not in this position as it has different plumbing.

Correct[biggrin]

I recon the D4 2.7 is actually probably less problematic than the 3.0l,although there are less of them around.It was improved in many areas after the D3.

And with a bit of a tickle from BAS,certainly has some go.

Now i need a rock to hide under[biggrin]

I think the best thing the 2.7 has going for it is the Territory replacement engine option when the crank lunches itself. Agree also that with a fiddle it’s as good power wise as well. Less complex too with single turbo. In retrospect I’d have gone 2.7, but I do like my HSE mod cons.

[kelvo]

Just had a look at mine, there is no way I can see how it could cut the top hose. There is about 8mm clearance at the closest point, I can’t even see how you could incorrectly fit the engine cover either.

My engine cover is dated March 2014 and is factory fresh, ie it has not been modified/cut.

[DiscoJeffster]

Earlier ones like mine were much closer than that. Only a few mm clearance.
You do realise that the engine rocks side to side but the hose at that point is fixed. This is how it wears, but yes, with that much clearance it’s ok

Exactly what I thought when I looked at my friends engines both had the same large gap. I thought it impossible to touch the hose.

But, there it was cut half way through on the side here. Feel in this location as it’s actually hard to see.

I imagine hose gets soft and slightly expands and engine rocks enough. The edge of the plastic cover is sharp as a knife.

https://uploads.tapatalk-cdn.com/20181118/bd203b507e9e7a2823cb0802f36880ea.jpg

[DiscoJeffster]

So mine was half slit. I’ve since replaced it and dremelled off about 10mm and it’s still touched (mark on hose) but no cutting. The engine clearly rocks enough under certain conditions to still touch.

[Eric SDV6SE]

That looks like a bit more clearance than originally on my cover. I’d still be modifying that to give it as much room as possible. I cut mine out to the corner, then finished it off with a die grinder, nice smooth finish, can’t hardly tell it’s been cut. Might still fit some protective hose around the edge, as per Scott’s LRD414 mod.

[Odysseyman]

Just to give an update on this:-
My nearest dealer (Doncaster Land Rover) have agreed to replace the hose and modify my engine cover to provide better clearance, all under warranty. (My warranty expires next March.)

The technician who evaluated it did say that he had seen more hoses cut on the inside, i.e. the left hand side of the hose as you look at it from the front of the car, so it may be worth keeping an eye on both sides. I suspect that is what that bit of protective sleeving is intended for.

Apparently the part no. has been superseded too, and is backwards compatible. The part no. I have is LR118802

Had mine in for it's 5 year service and mentioned this. Dealer said that there had been a bulletin out about this and the problem had been sorted. FWIW mine was ok but I've only got about 33000 kms on it so probably not as much engine movement as some.

Martin

[lrdef110]

Probably in short supply as I have been through 2 top hoses since July this year. Now has protection added. They are not cheap hoses either. There must be a fair bit of movement of the top cover on corrugations and blacktop vehicles may not be as susceptible.

The top cover does not move independently. The engine moves but the radiator is fixed. The result is that the cover contacts the hose as the hose can’t move. You need enough cover clearance so as the engine moves and the hose flexes, there is enough gap so they don’t touch.

Mine has less than 33,000 kms and had significant wear, you can just see the steel structural cables appearing in the old hose (see post 32). Would be interesting to see that bulletin, anyone here have access? I haven’t seen any damage of the new hose since I trimmed the cover and put protective rubber around the opening.

i think there’s even more to it than that.
I’m thinking that as the motor get hot the hose softens and swells when under pressure, and this, combined with the engine and cover moving in sync, particularly when revved a bit, causes the cover to abraid the hose. Try revving your motor (a good brisk rev to almost full revs) and you may see what I mean.

Here’s a photo of my new top hose and modified cover completed under warranty by the dealer today. I’m not sure I’m happy as even though they have trimmed the cover away, it is even closer on the right than the original hose was. Mine cut through at the right hand side of the hose a you look at the photo. They have allowed plenty of clearance to the left but that wasn’t a problem for me, although they did say they had seen that side cut as well. I’m going to watch it very closely. Also that reinforcing sleeve on my old hose was down the bottom of the hose nearest the engine, so there must be some sort of peristaltic movement.

David

[DiscoJeffster]

Yeah I’d get that cover off and scallop it out to the edge. That’s way too close for my liking

[Eric SDV6SE]

The hose does swell when hot. The protective sleeve needs to be fixed in place otherwise it just slides down the hose again.

While I'm waiting for a new hose, I used electrical tape to secure the sleeve in place

[LRD414]

The sleeve doesn’t stay in place because that’s not where it’s meant to sit and not what it’s meant to protect. Effort is better spent on enlargening the opening and/or adding edge protection something like I’ve done.

i think the point I was trying to make was that this was done by a DEALER under warranty and that they seem to think it is an adequate modification. Maybe I was too subtle. I definitely think it’s inadequate.

New genuine hose arrived Friday from Rimmer’s UK, just need to get myself some new long life coolant and will be set. (I’m also replacing the coolant outlet and flushing the entire system). I note that the sleeve on the new hose seems a bit longer.

Can anyone point me to the sequence to drain, flush and refill the coolant? Have had a google and checked here on AULRO but haven’t seen a step by step for a D4.

Thanks in advance

I couldn't see how to easily get the old hose out without removing things so I just undid the clips at the end of the hose and didn't bother about the fancy plastic bit that probably was most of the cost. Can't see why I couldn't find a similar shaped hose in an auto shop. Why does it need LandRover on it?

[LGM]

So after checking my top radiator hose in my D4 3.0L and seeing what would be best described as the smallest of marks I decided to get my LR service agent to change it out.

It is noteworthy that my LR service agent had previously noticed the hose rubbing on the engine cover some time back and put their version of a protection strip on. This was without any prompting from me and was, from memory, only briefly discussed at the time. Anyhow I picked up the D4 from them yesterday with the new top radiator hose fitted. They handed me the old hose and said they thought it would be a really good spare for my travels.

On inspecting the old hose that had been on the vehicle since new in 2011 I was amazed at how good a condition it was in. Apart from the very slight rub mark that the unprotected engine cover had made it was in really good nick. Remember this is on a vehicle and has seen 254,000km of travel of all sorts. That augers well for the rest of the hoses fitted to the D4. I had really thought that after all this time and the work the vehicle had done that the hose/s would show signs of perishing? If this hose is anything to go by not so!

[4bee]

Offering the old parts back???


Makes a refreshing, pleasant change, usually I've had "Sorry mate they're in the skip &/or the Skip had just gone"

Always puzzled by that attitude as though they have something to hide. As if?[smilebigeye]

I would just like to see them in a plastic bag & in the vehicle. [bighmmm] They could be some other person's old tat especially if the parts are a concealed part ie. not a Rad hose or like.


Do I do them an injustice? Probably, in some cases maybe.[wink11]

[Odysseyman]

As OP I’d like to give an update on my top radiator hose warranty claim.
I took the car back to the dealer and this time did a really good job. The service advisor told me two things, that they find that repositioning the hose by twisting it away from the engine cover gives really good clearance, which it does, so I’m happy with that.
He also confirmed that the webbing is there to protect the hose from any rubbing/contact with the engine cover.
So im satisfied that the warranty repair is good but I will, of course, keep a close eye on it.
i’m happy to say Doncaster LR looked after me well on this and a couple of other warranty issues.

Ok so yesterday out in the Vic High Country in our 2016 D4 SDV6 after about 200 km I got a low coolant warning light. We found the top hose neatly sliced open, about 2cm long, by the top engine cover. Has anyone else had this problem??
I’m at our Indie at the moment and they say there is not a top hose anywhere in Aust or UK. Grrrr ! The car was serviced only 2 weeks ago and I have a feeling the top cover wasn’t positioned correctly but in the heat of the moment I was too distracted finding the leak to notice it’s position before I took it off.
So, is this a common problem? Surely not!
And can anyone help with a top hose please?
Cheers

PS I’ll post this in the urgent help thread as well.You are my hero. Mine was on the way. I cut back the cover and will get the hose replaced next service.

Hi guys I noticed mine is has rubbing, so I've ordered and I received my replacement hose.

Any tips on replacement. Besides waiting for it to be engine to cool before changing it over? Access looks a little challenging, looks like I have to remove the intake cowl to get to one end which looks like a simple wishbone retaining clip, but not sure how to tension the hose clamp end? Can it be done with basic tools? Or can it wait till my next service?

When I found mine cut through I first went to my usual guys and, as they couldn’t source a genuine hose at the time, we temporarily bodgied up a similar one off a Hyundai. Both ends were relatively easily accessible with the top cover off the engine. I think if you ditched that strange looking clamp which goes on the motor end of the replacement for an aftermarket one with a screw/nut you can fairly easily reach to tighten it with an 8mm (I think) spanner.

When the dealer eventually fitted the genuine one I was concerned there still wasn’t enough clearance and they adjusted it by slightly turning the hose at each end to achieve the desired clearance. You may need to do this a few times, each time replacing the engine cover, until you are sure there is sufficient clearance. You can also trim a bit of the top engine cover with a Dremel or similar to achieve a lot more clearance. I believe at least 1cm all around the hose is desirable. I think there are photos of this further back in this thread.
Hope this helps,

Yep, giving any hose a bit of a twist & changing it's direction under tension can usually clear an obstruction but it is a bit trial & error as you sid.

[Petetheprinta]

I recently had all my hoses changed by an Indie here in Adelaide. I kept all the old hoses as spares, they appeared to be ok, no obvious cut in the top hose. On return from our 13000k trip I had a good look at top hose and sure enough was cut through about 50%. Happily enough indy replaced hose with new at no cost and dremelled the housing for me. End of problem.

AND I got bumped by the specter of the sliced hose. Thankfully I noticed mine before it had sliced through, but there is a deep scoring on it's side. I'll post pictures later.

I found a replacement hose, but they are charging a pretty penny for it, and I won't even bother going to the dealership because I know they will charge double for a part that will take 4 months to arrive (wonders of Brazillian customs), So I cooked up another more permanent and rugged solution: I'm considering making the bent part in metal (got a LOT of stainless laying around) and using industrial pressure clamps to hold each end of the hose together, maybe wrap it up with rubber so it won't make any clanking noises. We'll see how it goes.

At worse I'll have to buy a new hose, at best I got a permanent solution that will last longer than the car [biggrin]

[rocket rod]

How old is your car? It will be a warranty job? Or to get a new hose go to a Ford dealer instead as I think they will have an equivalent item.

[Willi Tom]

Mine is from 2010, so no warranty there. And ford never even dreamed about bringing anything similar to Brazil (sadly). The only other make I can think of that would have that hose is Jaguar, and that would be expensive anyway.

So yeah, I'm going to try the stainless steel solution. It'll still have quite a bit of rubber preserved, only the bend and the section that touch the engine cover will be replaced, so the engine movement is not an issue.
The only other issue is rust, but since I'll use 304 stainless, it's non-existant. IF it works, it'll be a lifelong repair (stainless tube will probably last longer than the car's chassis) AND will be something I won't have to worry about ever again.
IF it doesn't work, then I'll have to take the bullet and just buy the proper hose.

That's why I'm going with the mod: It's a zero-cost solution to a problem that WILL arise again if I just replace the rubber hose for a new one (the engine moves quite a bit, so even cutting up the cover a little WILL cause the cover to rub on the hose, only less).

Seems to be the way of the world these days, unfortunately, Willi or Tom. We buy a new vehicle then have to set about modifying bits over time to make them more reliable than the bits the highly paid Design Engineers thought were adequate for our conditions. They then take the user's ideas from websites such as this one & improve their products. Maybe.[bigsad]

I don't have that problem anymore.

Good luck with your modif.

Previously discussed on this forum has been to remove the engine cover entirely. It was thought to be a good thing to do and as a consequence it's not there to rub the radiator hose at all.

Martin

[Willi Tom]

4bee, I agree completely. It's not the engineer's fault, they do their best with the budget they got, but in the end, design flaws WILL happen.
One bloke swapping a section of hose for stainless tubing is ok, but the manufacturer doing that to 1million cars is prohibitively expensive (I don't think they even use stainless 304 on the car at all, the material IS expensive), so I understand.

And it's tiny stuff like these mods, improvements and tinkering that really help us make these cars OURS. The LR4 isn't that friendly to user-performed mods, but it's not impossible, and some awesome cars in this forum are a proof of that.

Anyways, decided to get my hands dirty and see if I can get this over and done with.

Removed the hose, which was fairly easy, only two pressure clips holding it in place:
151028

Also the engine bay was surprisingly clean for a 10 year old car. Only the expected ammount of dust and diesel grime, nothing out of the ordinary, but I've seen newer cars with FILTHY engine bays.

The damage to the hose:
151032

Yeah, it was VERY close to rupturing.

Cut it off, comparing with the steel bend:
151031

I will enlongate this bend by welding some stainless tubing. Got two different sizes. One slightly smaller and a thicker one. I'll test the hose fitment on both once I eat my lunch.
The tubing:
151030
The smaller one has a much thicker wall, which I think I'll have to thin out on the lathe. The thicker one got the ideal wall thickness IMO, but if the hose doesn't fit around it, at least I can go with the smaller one.

Also, there was this tiny little hose with a weird plug on it hanging around in the engine bay. It was held by a clip that was attached (very tightly I might add) to the coolant hose.
If anyone can tell me what it does, I would love to know.
Here is a pic of it:
151027

EDIT

Well, I'm back with some news. Used the thinner, thick-walled piping, welded the bend together and machined some grooves to make sure no hose would even dream about slipping off.

Here is the bend section after the welds and machining:
151038

End result after cutting the hose and connecting everything:
151037151036

And the bad boy installed in the car:
151035

Decided against cutting the engine cover since the bend made it all pretty safe. The plastic can rub against the steel all it wants now:
151033151034

Tested everything, ran the engine until it reached working temp, then went out for a spin. No signs of leaks or anything of the sort.
Seems like a success.

Diff breather tube?

replacement front diff breather Disco 3 and 4 (https://www.aulro.com/afvb/l319-discovery-3-and-4-a/256850-replacement-front-diff-breather-disco-3-4-a.html)

[discorevy]

It's for bleeding the cooling system , as well as the bleeder on the expansion tank. Necessary after say .....replacing the top hose.

[DiscoJeffster]

No it’s not the diff breather tube. The tube in question is the coolant bleed screw fo when you have to refill the coolant. It’s the same as the one on the coolant tank and at the back of the engine.

Come on, do tell what you had for lunch, some exotic Brazilian dish I suppose, my mind is wandering?

Nah, it was just the brazillian staple of beans, rice, beef, fries and salad on the side, looks like this:

Simple, tasty and keeps a man up through his day (lots of carbs in it though)

Anyways, thanks Discovery and DiscoJeff for the clarification, so it`s basically the seal for a vent on the cooling system. Good to know. I'll check how one flushes the cooling system and refills the fluid when I have time.

[4bee]

So, sort of a "Morning Tea/Snack" thing?[biggrin]

Looks good to me, & thanks.

I reckon some of us here could use that.:Thump::Rolling:

The only thing I would be concerned about is the cover rubbing against the worm clip on the top left side. Maybe spin the clip around a bit so it doesn't touch?

Nice bit of DIY, good to see. 10 min with a Dremel on the cover and 30 min replacing the top hose and coolant outlet did it for me. The stainless elbow is still rubbing on the cover, but minor issue. I’d also move the jubilee clip fasteners around so that they don’t rub on the cover and fan cowling.

You do need to crack open that bleed valve after opening the coolant system to let air trapped in the system out.

[Willi Tom]

thanks everyone for the heads up. And I'll check the bleed valve for air, but shouldn't the overflow reservoir receive any air trapped in the system?
Anyways, I'll be moving those fasteners and bleeding any air left from the system this afternoon.

So far this mod has been doing it's job: no worrying about a coolant leak and something left there that no longer needs replacement.

I also noticed how thin these rubber hoses are on the LR. The walls might be mesh-reinforced but they do look thin. Maybe because the engine moves a bit so they need to be flexible, but if any other hose causes trouble, I'm swapping them for the heavy-duty stuff...

[RANDLOVER]

Something else to check on older vehicles is the condition of the plastic radiator as the little top fitting on mine came adrift while my mechanic was chasing an oil leak, luckily he is a great problem solver and managed to glue it back in as a new radiator was a 6-8 week wait. When he removed the old one the top large, barbed fitting edge just crumbled, so definitely on it's way out.
