I have a 5.0 2010 XJ and I just had a coolant leak fixed.

Resolved Question:

I have a 5.0 2010 XJ and I just had a coolant leak fixed. They replaced the water pump. I don't know if I'm being paranoid or not but when I got the car back last night it looked abit low in coolant so I filled it up and then after a drive this morning it looked low again so I filled it up again. Both times the engine was hot after a decent drive. If the engine is hot will it appear there is less coolant ? Should I see what it is like after a good drive and then let it go cold before I check it again ?

Hopefully i can help..

Best to check the coolant level when the engine is cold ideally,left overnight and check in the morning and top up if required to level mark and then monitor the level from then on..if there is still continual loss of coolant then you should check for the possibiliy of a coolant leak,especially so around the water pump again although they are from i recall fitted with revised water pump due to the older failing due to seal failure or coolant system pipe work removed to get the pump out etc..and the rest of the coolant system circuit,just to be sure you dont have small leak which manifests itself when the engine is upto temperature..this maybe something to maybe bring up with the garage concerned if need be if the problem still occurrs..but in the mean time.monitor the level ..although if the level does get to critcal low point in the tank you will get a message up on the screen to alert you to check the level..since the tnak does have its own level sensor fitted..I do hope this helps..if you need to ask anything else or include anything further then just continue before you rate
