I have a slight leak in the front left of my xkr. I seems to center on a part marked Hella PA66-GF25. See attachement.
Jaguar forums and internet searches come with nothing that looks like it.

I think it is a coolant distribution valve. Does any one know what it actually is,
whether a replacement is available, or can it be tweaked to stop leaking?

I tightened the large hose connected to it and tried to get the clamp in a better position, but it still is dripping ever so slowly.

Any suggestions?

 

Try doing a search for intercooler water pump. Jaguar part number is C2C1314 if you'd like to search for that too. Could just be the hose that's shot though, which is much cheaper than the pump.
