Jaguar XK8 Problem Report
Jaguar XK8 Overheated Engine Due to Stuck Thermostat
The thermostat may stick partially closed resulting in an engine to overheating condition. Replacement of the stuck thermostat should correct this problem.
I noticed that my temp guage was heading into the red zone going up a steep hill. I was able to get the car to a Mc Donalds and had it towed to my Jag dealer. The problem was a stuck, partialley closed, theromstat which they replaced. I also had them replace the water pump with the new metal style. I am now seeing the ABS error light come on intermittently. Not sure what to do about that. The dealer checked the car and cleaned the ABS sensor plug contacts on the right rear wheel, which seemed to cure the problem for a few months,but the problem is back. - Visitor
Mine was stuck open and I got a low engine temperature lite that causes the engine to go into low performance mode - Visitor
Engine gets very quickly to operating temperature and after driving 10 miles the coolant is pushed out the overflow and need to top up expansion tank when stopped although does not empty the system . The top and bottom radiator hoses significantly different in their in temperature and suspect thermostat is sticking half open and have ordered one .The engine didn't overheat on a100 mile drive but lost a[pint of coolant .My car 4 years ago had the new aluminum thermostat housing fitted but looks like that one is playing so will try and do it myself .How should i bleed the system . Should i remove the top cap with the female socket drive in it ? Please to see it is a common problem Regards Nigel - Nigel Adelaide
