2011 XF 5.0 has a serious coolant leak visible above the transmission bell housing. I can't see what is actually leaking. Any ideas or answers?

 

Its likely the PLASTIC rear coolant crossover.


It's the plastic thing with the hose coming off, below the wire loom at the firewall.

Just replaced mine in August

It's like $60 from Jag, be sure and replace that hose coming off it too.

My XFR is supercharged so it was a bit of a bear as my SC as will your intake must come off. But if you've ever pulled an intake you can do this. My post when I did mine.

Search XF (rear) coolant crossover its the same on all Jag 5.0 engines and someone did a normally aspirated 5.0 before I did my SC 5.0.

 

Yep, it is not that bad of a job. But it does take time to do it right. Mine did that at 40k miles. I replaced my waterpump and the other lines as well since I don't want to have to go through that again.
