Good evening all,

I have been searching the forum and the interweb for how to remove heater core on 2004 XJR. Have had flushed and aux coolant pump checked and pretty confident core is problem. Soon it will be 5° in Michigan with 2' feet of snow, so I need to fix without dropping a grand on it and to figure how big of bottle of Tylenol to get.

thanks
Bil

 

You really need the workshop manual.

I cannot vouch for the above but a while ago I downloaded a workshop manual
and the heater core removal procedure is in the "Electrical" section.

 

Thank you very much. Link had some poor taste pop ups, but it downloaded. For those looking heater core removal starts on page 4772.
