My 2011 xjl supercharged overheated near my home. It is not my daily driver. It has 80k miles on it. I've put 50k miles on it in the last 5 years. I was able to pull in the garage to check it. I found coolant coming from behind the water pump and also underneath the car in the middle. It is coolant coming from both places.
I finally replaced the water pump, after looking at a thread from a guy on the forum. I hate that I can't remember his forum name, since his post with the pictures helped me so much. Well, after I replaced the water pump there was no more coolant coming out of the pump. But I noticed that cooling is stilling coming out beneath the car. I have not started the engine back up. Any thoughts guys?

 

it will be the 'y' pipe that is located under the inlet manifold it splits along the seams search the forum as there is loads of information

 

Thanks Pete
I'll research that Y pipe.

 

miket7, keep in mind that the tray under the car is going to hold a lot of fluid. If your overflow bottle is maintaining fluid, but you still have some dripping out the bottom, then I would be wanting to drain the tray first. Unfortunately, you have to pull the tray from under the car to lean it enough to get all the water/coolant out. not a hard job, but will take a little bit of work. You may want to do this anyways just to help pinpoint where the coolant is coming down at since the tray covers most of the underside of the motor and will redirect the coolant to a different location and can lead to confusion.

 

Yeah Thermo
I should have removed the tray. Also, after the coolant runs out, the reservoir is very low. Its not holding any coolant.

 

You might be thinking of Bigg Will? He has posted a number of well done repairs. He has passed 100K in XFR now.
There is thread about that too.
