While replacing my radiator, I noticed the coolant hose coming off the supercharger pump on my 04 XJR could use replacement (#8 below; part number C2C10869). It's been discontinued and from reading some old threads, it's been unavailable for a while.





Here's how mine looks now:



Other than looking for another used one in a junk yard, wondering if people have had success with making their own? Any particular suppliers that make decent alternatives? Couldn't find any on eBay or the usual part suppliers.

Looking to get some options before deciding whether or not to reinstall it.

Thanks.

 

It looks like its been a part number change, try C2C26617

 

I remember seeing that part number too but seems like a different design and not applicable to the X350 engines.

 

its the same hose for vin G43622 and up, its worth a try.

 

I have looked extensively for this hose in either used or new old stock form. It's totally extinct. I have researched how to make a silicone hose myself, but... it's more complicated and requires some tooling than fits my capabilities. I've tried using two 90 degree bends joined together but was not thrilled with the results. Right now I'm running the OEM hose which is holding up and not in bad shape but it's the only coolant hose I have been unable to replace. I've thought about sending out a spare hose to a manufacturer but... so far I can't even find a spare hose. Keep me posted if you get a solution.

 

Well this is unfortunate . Was not aware of 'R' hoses becoming unavailable. Will there be more dropping out soon? Another challenge to keeping these cars on the road.
One could cobble together welded stainless tube elbows with rubber hoses on the ends, but I imagine that would difficult to make look right, not leak, remain flexible and fit in the confines of the location.
What is the inside diameter of the hose? Does anyone know?

 

I measured 0.905" ID and 1.185" OD. I reached out to Gates (since they make aftermarket coolant hoses) but they couldn't find anything. Recommended I reach out to Continental. It's definitely something that can be done but it would be cost prohibitive to make the tooling for a handful of customers.

 

. I believe the two ends are different sizes. I've looked for uncured / to-be-vulcanized hose that I could bend and cure at home, but that doesn't appear to be a DIY industry.

 

Try finding copper fittings, that just fit inside of the hose.
Duplicate the hose, with its bends.
Leaving just enough space for a short piece of hose.
On each end. to clamp it into place.

 

I know this thread is 2 years old but that hose is still unavailable. Did you ever find an alternative replacement for it?

 

If seekers were having to fab their own two years ago, that's probably still the only 'fast' answer, but more-so.

It isn't than dificult.

A factory made the originals from scratch.

Hydraulic's shops as serve agro and heavy construction industries make hoses to-order off the ruint remains of failed ones every day, all day.

This is not into that range of high-pressure, so techniques can be simpler, as can use of less-coslty fittings and tubing.

A DIY fab need not LOOK the same as OEM. It only has to serve the needed FUNCTION well-enough.

 

I saw a clip on YT recently about putting springs inside hoses, then using a heat gun to soften the rubber. The hose is secured in place while it cools, and the shape is retained when the spring is removed. The springs are made in a variety of sizes for plumbers to bend pvc pipe, but they seem to work for rubber hoses too. I just checked on AliExpress and found some for sale.

A pan of hot water will do this, but the heatgun would be faster.

 

Downside is that a(ny) given hose material as can be bent in water (maxed to open-air boiling temp) can as easily be UN-bent by higher-yet temps as can occur in spot areas underhood in an engine bay.

Depends on where it has to serve, of course, but even those carryiing stabilized temperature coolants can be under a Bar of pressure, too.
