View Full Version : Oil Cooler Hoses, now 3rd time in 10 years

Notice I have another oil leak from one the Oil cooler hoses. The one from the oil pump to the radiator. I recently replaced one of them now the other has gone.
The Disco is 10 years old and They had been replaced by heavy duty Pirtek braided ones before by previous owner.
They have gone brittle.
It must get very hot down there in the engine bay. And seems like These hoses need replacing every few years, as this will be the 3rd set.
Any one else have this bother?

I noticed when I was looking at Disco's the standard hoses all seemed to be leaking or at the best wet, mine is the same.

My thought was to replace them with Enzed oil hoses which have a push on coupling (so there is no metal section or external crimp). I've used these hoses for many years on a lot of rovers and have never had one blow off or leak.

I'd also be interested in opinions/comments from others on the standard LR hoses and remedies they have done.

Best regards

Translation...

Pirtek hoses were wrong for the application.

There are higher temp rated gear available.

Suggest a chat to EnZed

Hrm that's not good, anyone replaced them with standard LR hoses. Do new ones end up leaking?

If they are not prone to failure I guess it's just an annoyance if you are the type that hates any form of leaks not matter how small.

Replace mine with the new style from LR 2yrs ago.

Still going fine, even after 30,000 KM of Australian roads. :p

I use Enzed for this, and have had NO issues at all, as we use pushtail fittings and Hitemp blue push on hydraulic line, not swaged. I can get some part numbers if anyone is interested.
I also used all these for my turbo oil drain off, and the water cooling hoses through the core. No leaks yet, and I can see 600+ deg from the EGT's regularlly.
It also has the added benefit of user serviceability, if it springs a leak or a damaged hose needs replacing, you can just cut away the old one and cut a new length, lube with oil and push it over the fittings. I would carry a metre of the stuff on a trip, it retails for about $35/ m I think.

As said, a talk to enzed is a good idea.

Justin,
I have a '96 petrol Disco with weeping hoses and joy-of-joys there is an Enzed agent in town!

Would your pt nos be applicable to my car? If so please post them,
cheers Chazza

No worries Chazza, I'll look it up tomorrow and post em up. Actually, I'll get the info from the horses mouth so you can actually ask your enzed rep for the exact job.
AFAIK there would be all the same bits at his disposal as over here.

I think I will go back to my original thought and also replace them with Enzed hose/fittings as I said I've never had problems in the past with Enzed stuff.

Yes Justinc, please do post the info with regards to the particular hose used, thanks.

Best regards

If it helps in the short term, what our bloke ( Hi Nigel) does is cuts the swaged ends off, modifies 1/2" pushtail fittings by drilling them to 13mm, (a space around allows silver solder to sweat in well) inserts the original cooler line end(Cut off and cleaned etc) into the fitting and silver solders it on. This means you can just lube up the 1/2" blue HiTemp line and push it over the barbs of the pushtail fitting. Meaasure the length accurately, because after the line is on, you can't pull it off short of cutting it off. Use new O rings on the other ends and re fit. I actually bought these fittings once from a hydraulics supplier, and tried to make my own. Way back when my silver soldering techniques were pretty average(!) so I trashed that idea and hid the results in the big blue Collex filing cabinet outside....Then rang Nigel.:D :D

I'll get some actual fitting numbers for you, then give them to your bloke.

More than an annoyance, My front diff is absolutely covered in oil. And with this hot temperature we are experiencing, I'd hate for it to blow and leave me with a cooked engine out of oil:mad:
Also a pain in the asshole to undo that piddly little hose bracket that holds the 2 hoses together underneath, have to be a little handed contortsionist:o

Justin, What kind of price should each hose end up costing?

And might be asking a bit much, but would anyone have photos of the modified EnZed hoses?

Pavo,

I charge $120 per hose including GST, after I get charged for the callout and his time and parts to do it. This includes O rings but not fitting and degreasing. Fitting usually takes about half to 3/4 hr and could be longer if the MESS is bad!!

They look similar to standard ones, except soldered fittings and blue flexible hose.

Factory ones are about $150 each, and will leak eventually and aren't repairable easily like these now are.

A good thing to do as a preventative too, as the factory ones WILL leak, its just a matter of time.

Thanks for that, Justin.

OK, Here are the numbers for the hose bits,

the hydraulic hose has a part number of: 836-8
The 'Pushlok tails' have a part number of: 39982-8-8
The se*y little yellow finishers for the hose are: 590126-8 ( Not really required, just look finished)

Hope this helps but AFAIK these numbers would only be useful to Enzed stockists/ repairers.
Give me a call if you need any more info.
