Question about 1995 Jaguar XJ12
Car is overheating when going over 55 MPH with AC off.
Car is overheating with AC on.
Car is overheating with when stopping at red light, with AC off. Need to put car in Nuetral at light.
Seems like the thermastats are closed.
Waterpump is not leaking, nor the hoses, nor the radiator, etc. No leaks.
Hoses going into radiator are not extremely hard.
Car cools down in 30 min or so.
I then can drive car under 55 MPH and temp guage is at N or one notch to the left. If I go over 60 MPH, the temp gauge goes to H, red zone.
The aux fans seem to work. I turn off car and the aux fans keep running.
I turn AC off, put car in nuetral and reve the engine to 20 to 25 rpms, it seems to lower the temp guage back to 2/3 to right.
Any suggestions welcome.
I plan to change the thermastats and related relays and switchs.
Also, I will buy new relays and switches for related cooling system system components.
I will also take the car to get a computer diagnostics.
Just purchased the Jag. The prev owner had the XJ12 sitting in the garage for 3 years. He changed the antifreeze before I purchased, one week ago.
Any suggestions welcome. Thank you.
