Afternoon all. Hoping to pick the brains of people who may have had similar.

2007 FFRR 3.6 TDV8, runs and drives perfectly. Doesn't overheat, when running no coolant leak at all. However, when you switch it off, it all happens

It will empty the coolant onto the floor. Seems to drip of the N/S bottom arm at the rear, and when jacked up on that wheel,it almost looks like its running out of the chassis rail.

Anyone had this before? If I fill up when the engine is off, no leaks, run, no leaks, switch off, and it dumps everything.

Thanks in advance all!!

The Fuel burning heater is in the NSF wheelarch, behind the liner, could be an issue with that, the hoses or valves in that area.
In any case, the first thing I'd do is remove trim in that area and use a pressure tester to reproduce the leak.

Thanks for the speedy response. I’ll give that a go. Never used the heater, but I was playing with the control buttons, maybe that’s caused something to happen.

There's nothing you could have done to make it dump coolant...
