A couple of weeks ago i had to replace a radiator with 3 years a 13k miles on it. It failed massively.

Over the weekend, I was unable to open my hood because the cable slipped out of the latch. Thanks to the forum, I raised the car and put my hand up high enough and easily unlatched it and solved that problem fairly quickly……..

Unfortunately while laying on the floor under the car, I saw some coolant wetness underneath the thermostat radiator T hose. It’s not dripping yet, but it’s wet. I replaced this hose in July of 2019, 30k miles ago. Guess I need to order another one.

The 13k mile radiator/ 3 years old radiator failure was upsetting but not totally shocking since I replaced the original radiator with a aftermarket Niesens part.

The upper radiator thermostat hose is more upsetting. I replaced it with a Jaguar original part. Surely they are meant to last more than 30k miles/5 years? Or would you guys say this is normal ?

looking forward to some feedback on this. It’s going to get fixed, but i am just interested in hearing how long these hoses are lasting .

 

G'day Mark. Not normal in my experience . . . not by a long shot. Did you replace "it" with just a single hose, or the entire assembly?

I ask because many failures occur in the plastic tube pieces that are interposed between hoses and which contain critical connectors that secure hoses with clips. I replaced all the upper and lower assemblies and minor hoses on mine many years ago, reasoning that I never wanted to go back there again. Mine was leaking badly in several places, despite botched attempts by PO to glue it together (!)

I replaced the lot including thermostat, using after-market parts (IIRC, Gates, at total around AU$200). Really long straight and offset pliers, and never an incontinent moment since!

I hope this helps.

thanks for you reply!

I replaced the entire fixture with a OEM part. The leak is so small now that it’s not hitting the floor. I just happened to see it because I was on my back underneath the car trying to reach the hood latch (the wire had slipped out)

 

Hi Dell;

yeah I know they fail on all x types eventually…. Replaced it on my previous x type myself , and as I mentioned on the OP had it replaced on this one 5 years/30k miles ago. The original part made it until catastrophic failure 13 years and 65K miles, but who knows, it could have been dripping and evaporating much longer than that. Last time my mechanic was able to put the car on a lift, take the tray out and finesse the hose out of there in 20 minutes. Sadly that guy is no longer at the shop.

But the fact that the replacement hose seems to have an even shorter lifespan than the original sucks

 

In the last few years every part that I've gotten from Jaguar has not been true OEM but, rather, a lower-grade substitution. My conclusion is that Jaguar is gradually, but continuously, contracting with alternate suppliers for all the replacement parts.

Your situation hits close to home. My '05 S-Type has original hoses. Normally I'd replace 19 year old hoses in a heartbeat....and I probably will....but I do worry about the new parts not really being any better than what's on the car right now!

Cheers

It’s a shame because they are still charging premium OEM prices. I guess they have to make up for the losses incurred from their current sad and bland generic vehicles somehow.
