At last I have found the cause of the coolant loss in my GU 3.0 TD that I was whinging about in my intro and I thought I would fill you all in.
After crawling over, in, through, around and under the engine bay for a couple of hours I have found a pin hole in the radiator, behind the edge of the radiator shroud. The edge of the inner shroud has been rubbing on the core and eventually made a tiny hole. When cool the pressure of the shroud sitting over the hole was enough for it not to leak but when up to operating temp and pressurised it would leak out over a couple of days of driving.
Now a question for you all. The shroud seems to be quite loose and rattles around a bit and I am concerned that the edge of the shroud can sit against the core. Is there supposed to be some sort of soft foam packing between them like that around the front of the radiator?
