As you have already posted an Intro on March 9th ( https://www.jaguarforums.com/forum/n...g-game-243872/ ), I've merged your two latest Intro posts and moved your question from New Member Area - Intro a MUST to X150 forum. This is the place to post technical questions about your model.

Could be the valley pipes (hoses)? A nightmare to replace on SC, but not so bad I think on NA engine (yours)

 

It would be necessary to remove the intake manifold if the valley hose has burst (which seems likely). I recommend to the OP that he take this opportunity to replace all coolant hoses.

 

+1 on replacing all cooling system hoses along with the water outlet pipe assembly while the inlet manifold is removed.

Based on the description of the leak, it's most likely the heater return hose or one of the two EGR feed hoses has failed.

 

If you plan to just fix the one leak, I'd clean all the coolant off, get a pressure tester and pressurize the system to pinpoint the leak while cold. It still may be obscured by your intake manifold, but cant help to make sure the coolant that has leaked has not moved around.

On my own car, since its 14, just like yours, I'd use this time to just shotgun the cooling system consumables. The little hard lines, the hoses, all done so that you aren't playing whack a mole over time replacing them onesie twosie. It'll be under a grand, even with Jaguar prices, and I think for a grand, you are buying a good bit of insurance since overheating would be the most likely reason your 4.2L car would grenade an engine.

 

true enough... but the opportunity to completely clean and change the supercharger oil and components.
So it hss gone from last winter: change the sub frame mounts, to this winter: change all the hoses.

 

Again thanks,to all that have replied!!! I'll be getting to work this weekend,sounds challenging but to avoid dealing wit dealership and excessive cost ,I'll getIT done, thanks

 

Four years ago I replaced all coolant hoses and the thermostat housing in my 2007 XK. Maybe you might find my post to be of interest: 2007 XK Cooling System Service - Jaguar Forums - Jaguar Enthusiasts Forum
Good luck with your repairs!
