There Are plastic cooling lines from the fill reservoir to the radiator and similar clip on flexible air breather hoses on the engine here and there

Has anyone successfully replaced them with something else that's not so "delicate"? Attaching the ends with those clip on systems seems to be the biggest issue, otherwise it could have been done with flanges aluminium piping.
Interested in what people have done.& How.

The replacements are inexpensive enough -- why bother?

 

Because I despise plastic on cars

Half the car is plastic. I'm not sure why you would take a stand on this specific item.

 

I am curious about this too... I just killed my second one of these damn lines while working on the pulleys. They are awfully brittle and stupidly designed imo. Also, I apparently bought the last replacement set whenever I broke these the first time and now I can't find any anymore in my entire country so that's fun.

I suppose I'll just replace it with some hose and a hoseclamp. Should work in theory. I'll report back with measurements once done.

 

It is true...twenty year old plastic lines do get brittle. So does rubber.

 

The main difference is that a rubber coolant line is easy to replace with any generic hose and a clamp while this very specific piece of plastic with it's weird clip structure is very hard to get by. But I'm sure Jaguar engineers didn't have me in mind working on this car 26 years down the road

 

I replaced my broken line with a rubber hose. Real easy. 13mm inner diameter hose is a nice snug fit. Around 100cm length is enough. You Americans can inchify that for yourselves Seems to hold up well without leaks so far.

 

sort of looks light my field surgery on my 2001 back in 2013 after resting my hand on the radiator end: 6 inches and a hose clamp on the old pipe remnant and the radiator tit. I still have that piece in my tool box just in case.

Told this story before: I buy a new one from my local Jag dealer (had yet to hear about Rock Auto, et al), install the new. After changing out the secondary tensioners, water pump, TST and tower, stubby hose, cross over and temp sensor, and belt and belt tensioner, I take the car to Checkered Flag Jaguar for a one year service (oil and filter change, fuel filter, kiss and a promise -- whatever they do for $200). Looking the car over after getting it home, I noticed that my new hose is different. I had removed the taped on paper part tag on the one I installed, this one had the tag. Goes to show you, even the pros sometimes rest their paws on the wrong place . . .

 

I have rested my left wrist on a few radiator air bleed lines and snapped them.

 

You can tell a decent garage as they'll fix it & maybe tell you about it. The bad places will try to charge you & claim it was faulty when you drove in.

 

If I break it, I FIX IT!!!!!!!

Sometimes I tell the customer and sometimes it just goes out the door fixed and everyone is happy.(no point in beleaguering the situation)

 

Aye it depends on the customer I'm sure.

Garages I use a bit tend to tell me if they had issues, because they know I do some bits myself & will probably notice. Indeed the Jag specialist I use has been known to give me the car back with 'everything done but this*' then say you can do that yourself it's easier than other stuff you've done & tell me what needs doing. I'm sure a totally non-mechanical customer would just get it fixed & charged for it, and both of us are happy with the outcome.

 

This is true...and sometimes it depends on the ability to access the issue,
along with the tools required get it done without breaking things along the
way. As these ladies age, some parts are so brittle, they break if you look
at them the wrong way!
