Hi guys,

I just bought a 2012 Jaguar XF base model few days ago. Unfortunately, there's a coolant leak, and I had to take the car to the service department. The good thing is that the car still has 2 months of factory warranty and 2 years of CPO warranty left. So they changed my water pump, o-ring, and thermostat housing to fix the coolant leak problem. Another concern I have noticed is that the engine and coolant were still relatively warm even though I had shut off the car for 4 hours already. It was also night time, so it had nothing to do with the sun. I am wondering if this is normal for the parts to stay warm for that long, or is it signs of overheating or possible overheating in the future. Let me know what you think. This is my first jag so I am not too familiar with the mechanics and engines.

 

That all sounds pretty normal to me. The XF suffers from failing coolant pumps very regularly - an issue with the pump itself. Many people on here have had them replaced - we have had it done on our XF and our Land Rover (same engine).

The cooling system can retain heat for quite some time when stationary - not surprising to me that it was still warm. It runs at high temp and pressure so lots of heat to release. And once you stop driving there is no circulation around the system and no airflow over the radiator so cooling will be slow

Hopefully you are all set now - and wishing you lots of trouble free driving!

 

Ditto BritCar.....

The engine compartment stores a lot of heat...Knowing this, when I park mine for a long time, or after a long run, I open the hood to let the heat out..Heat will kill a lot of rubber and plastics if it's allow to bake in it.

Oh, I have a garage to park in...

 

These cars stay hot, if nothing is burning your fine.
