Hi All
I have an 04 S Type R with 120k miles on it....at 115k a top hose perished at one end, RAC man cut the end off and reattached it. Couple of weeks ago another leak - local garage replaced a vertical hose at the front of the engine that "was difficult to fit".
Tonight, another leak. Fortunately 8 miles from home, 3 top ups with 6 litres of water and we made it back. I would imagine the one from two weeks ago has come loose...but it could be yet another one...
Is this a common problem with Jaguar hoses/ S Type hoses of this age? Do they all need replacing at a certain age/mileage?
I'd welcome your thoughts

Hmmm...done 111,000 in my S-Type 4.2 V8 SE and no hose issues as yet. Note to self: check breakdown cover, hoses and financial situation.

Guy The one to worry about is the valley hose under the supercharger. Charger off job to replace and many £££s labour. Mine went at 90k. Other hoses seem ok so far

Just had a call from the garage....Guess which hose it is this time.....yep - the expensive one mentioned above. Have given instructions to replace any additional hose in the same area when it's all apart.
Is there a manual/diagram/schematic with all the hoses on it available anywhere?
Thanks
Guy

I've done the hoses on mine , the one under the supercharger is a nightmare to change , but they are not dear from jaguar dealer . Change all the small hoses while you are there as labour is the costly part !!

Or you can use silicone, a bit more expensive but last better Not initially made for S types but I can only imagine the top and bottom rad hoses will be a bit different.

Mine just went at 69k and the other one the OP is talking about went at around 58k. The one at 58k cost about £10 the other one was about £1k!! buzzsaw said: The one to worry about is the valley hose under the supercharger. Charger off job to replace and many £££s labour.

Just whacking silicone hoses on it isn't an appropriate solution.
I have a 944 and that started blowing coolant hoses a while ago. The issue was that the oil-to-water cooler was leaking slightly, resulting in oil getting into the coolant and the coolant becoming more viscous than normal. This seems to have resulted in the coolant system overpressuring, as the water pump struggled to push the gloopy coolant around the system. Result was the coolant system blowing at the weakest point. When that was fixed, it blew the next weakest point and so on.
This continued until I fixed the cooler and changed all the hoses.
In your case, I'd check that something similar isn't happening.

Can't see how comparing a 944 to a S Type really works as there is no oil/water cooler combo, only where the gearbox oil goes through the rad which again has nothing to do with the engine
It is not like valley hoses are unknown for going, as they do!

Rubber hoses do perish, and there is a lot of heat buildup under the bonnet of something like an S-Type R - superchargers are well known for it. If cost was no object I'd replace them all, but of course it is. Maybe replace the ones with high pressure and it particularly hot areas?

Other hoses seem ok so far This is spot on - The valley pipe went on my S type R and was a bloody nightmare to fix. Supercharger has to come off and it costs a lot of money in labour time. My bill was around a thousand quid .

Hi
It was 8 hours labour and parts at local non-specialist garage - £450 all in inc vat. Have done 1400 miles since it's been done (including M6 today!) and it's fixed

Hoses perish, certainly would not recommend cutting the end off and refitting as anything other than get me home ! Valley pipes are tough to fix but I had a main dealer engineer swap mine on his personal time, no need to remove the Supercharger, all done on my drive, took 2 hours cost inc pipes £250

I obviously remain open to information as to the other way this pipe can be replaced. I personally can't see how this pipe can be replaced in two hours - I have some images of the work which I will try to to find and post up.
