I apologize if I was putting my questions in the wrong forum. My car is overheating, its fine sitting still but once I get it up and driving it starts throwing the high temp and overheating red light. I have replaced Thermostat, Thermostat housing, water pump, also the sensor that's in the housing. The coolant seems to be moving like it should so I assume the radiator is OK. I am going to flush the radiator and try top check the fuse that controls the coolant fan. Is there any advice on what may be causing this? It used to say low coolant but the light has gone out, ive bled the system multiple times. Thanks for your help.

 

I would install an OBD reader (cheap on fleabay) and the Torque app on my phone or an Autool X50/X60 to see what the coolant temperature actually is before throwing anymore money at parts. My XF normally runs at 186° F.

 

I am also not getting heat into the cab. Once I replaced the water pump the heat did start to trickle in but it didn't last very long.

 

Definitely sounds like air in the system then, which is why it's overheating.

Did you bleed it following Jaguar's instructions (attached)? You have to run it with the heat on for a period during the bleeding process.

 

I haven't bled it exactly like that. I appreciate the help. A buddy of mine says I should look into a clogged radiator, or even my heater core. I'm thinking bleeding too but we've bled this thing daily.

 

Use a vacuum filler to put in the coolant. Not that expensive, very handy, the best way to fill coolant without needing to bleed. And one of the ways Jag recommends.

How often did you change coolant on this 10 year old car?

 

i bought this beauty back in June. I drove it for two months had a oil change done because I was going long distances. Right after I had the oil change done It popped up low coolant and I soon realized there was a crack in the coolant overflow tank. I replaced that and when bleeding it I parked uphill took the cap off and ran it at 2500rpms for 5 mins. Had no issues driving it. A few weeks later is when it all hit the fan, overheating and replacing all those parts

 

Im thinking I got some more air out today. I was just kind of checking around the heater core pipes. The top one I can feel hot water going thru it. The bottom hose is ice cold. I was thinking of switching hoses and trying to back flush to see if my heater core is clogged. Also I felt the auxiliary water pump it was also ice cold(although I'm not sure what its supposed to be lol)
