so ive had a coolant leak for a little while. today i finally decided to see where it was coming from and i tracked it down to the passengers side. there is a hard pipe coming from the block, that has a coupling, then into a soft hose. the leak is coming right at the coupling, then dripping onto the exhaust.

i couldnt find it on the EPC. i dont know what part it is, any help?

 

what causes hesitation on a cold start?

 

Safi,
You probably should post your own thread with your specific questions in the 308 forum here: XJ ( X308 ) XJ8 / XJR - Jaguar Forums - Jaguar Enthusiasts Forum

You will get more views and responses that way.

It might be the heater feed pipe.

Here is a JPEG file that I put together - photo from blackonyx.com, diagram from TSB 303-48am Coolant Leakage Heater Hoses, Parts diagram with part numbers from jaguar classic parts.com:

Octopus hose. $150ish- I just bought one. You COULD try and repair it, but it is a BEAR to get to, so I opted to replace and avoid having to get back there again. Here is a post describing the hose with parts numbers:
