I need help ! I own a 2001 Jaguar XJR Supercharge and my car is over heating. I have had the coolant hose, thermostat, water pump, and coolant tank replaced but my car is still over heating. the oil was checked and no mix, no white smoke coming from tail pipe to indicate a blown head gasket but my car will over heat after driving about ten minutes, I can let it run, turn ac unit on while the car is running(in park) and the temp gauge will display normal but soon as I drive the car after 10 minutes the gauge shoots all the way up. Lost and confused. can you help, thanks

 

I've moved your question from General Tech Help to X308 forum. Members here with the same model will be able to help.

Look up the posts in this section about the proper orientation of
the bleed lines at the coolant expansion tank. Lots of people
install them so that they "look right". That is wrong. They should
be crossed. You'll understand once you see the pictures.

 

I cannot find the posts in this section about the proper orientation of
the bleed lines at the coolant expansion tank.
