I suspect the expansion tank , more often than not as soon as the tank gets warm they weep at the seams
Good shout. The union at the overflow easily snaps, and the float switch eventually doesn't float! Easy DIY replacement in about 30 minutes. The complete tank available from Berkshire Jag components for about £26.Risonax said:
The issue is the a dignosed cracked plastic thermostat house. The bigger issue is Jaguar have discontinued the part, with no replacement. No UK stock.
Guess the car is now parts only. Shame.
Anyone know of sources for complete thermostat housing, non-supercharged V8 X350.

Nothing to lose so you could try using superglue and bicarbonate of soda to seal the leak.
Probably not a permanent repair but I’ve used this method on broken plastic parts many times.
The Thermostat housings become brittle with age, and are cheap enough to replace. If you are going to drain the coolant, jack the car high up enough, removing it, degreasing it, and making a temporary repair is probably not worth the effort.Probably not a permanent repair but I’ve used this method on broken plastic parts many times.
Try using a vacuum coolant bleeder, they are straight forward to use the only drawback is you need an air compressor.
I used one with great success on a Porsche Cayman which has a pretty convoluted cooling system, saving me a lot of faffing about with the bonus of knowing there were no surprise airlocks to show up later.
When you vacuum the system down you can leave it for half an hour to check for leaks too.

Just used one of these for the first time to fill an X150 XKR 5.0 which requires you to remove the coolant bottle and hold it in the air to try and fill it manually, and always gets airlocks. It was absolutely superb, sucked all the hoses flat, kept the vacuum for a while to make sure the system was sealed properly, then it filled the system from a bucket in about 45-60 seconds. No airlocks at all!I used one with great success on a Porsche Cayman which has a pretty convoluted cooling system, saving me a lot of faffing about with the bonus of knowing there were no surprise airlocks to show up later.
