I have problem with engine temperature.
For example when i am driving on motorway i will reach engine temp to middle(90deg) but when i am coming to exit and knock the gear out my temp will drop.
I changed both thermostats it is better witch solved very slow engine warming up.
Thermostats are both original from jag dealer.
Could my waterpump be failing?
That plug is for the transit relay which is removed at PDI by the dealer.
It should stow in a hole at the back of battery box or air box.
You temp gauge is displaying what is perfectly normal behaviour for many x types, so I doubt it's anything to worry about.
Thanks Billy
Reason why i am bothered is that i have very poor mpg which is probably caused by ECU forcing it to cold run mode(experience from tdi engine).
Do you or anyone have any idea where can i find coolant temperature sensor?
I changed both stats this weekend. Last relatively cheap repair is oil temp sensor but i have to find it first
If anyone have idea where to find it or better have picture post it please.
Thank you
If you've replaced both stats check there isn't contamination in the system keeping the coolant stat open. If the pump wasn't working the engine would generally over heat. These symptoms generally only rear there head when the ambient temperatures drop and the stat isn't closing properly.
Although they are genuine, are they the correct temp rating?
problem solved.
I put car to local jag specialist it turn up fans were kicking up too early.
Reason overfilled aircon to 150% capacity.
Now it will warm up roughly after 5 miles of driving.
