hello all,
I am currently chasing down coolant leak(s0 from the valley area. I just assumed the leak was from 22 year old hoses in the valley. I changed them and thought everything would be fine. No, still signifigant leak.

I disassembled and inspected the valley and I think the ls coming from the bypass gooseneck. there is a boss machined and drilled and threaded for a 4 bolt flange for the gooseneck, but I have a 3 bolt flange gooseneck and it is leaking where the 4th bolt would be. Do 2000 XJR"s normally have a 3 bolt gooseneck. Where might I get a 4 bolt gooseneck.

Thanks,
Dave Redline

 

So the induction elbow are all 4 bolt. There isn't a direct coolant line in that area.
If your engine has the AJ27 throttle body, they're fitted with a coolant line - that could be leaking as a wild guess.
The header tank can crack and leak coolant down so check that area also.

I cannot recommend the Jaguar site highly enough if you're a hands on owner...

SuperCharged engines have a different coolant block connector. (3 bolt connection)

 

thanks

 

I have found out that the part that I'm looking for is called a coolant spout. Is there a reason that a 4 bolt spout from anXJ8 wouldn't work on my XJR.
thanks,
Dave

 

It will work as it is the same part number (and still 3 holes).
