Thread: Top radiator hose sliced by top engine cover

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.

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.

The one on the 2.7 to watch is the small one running just above the A/C compresser pulley.

It would be unfair of LR to let just the 3.0l boys have all the “fun”.

Correct

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

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.

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.
