coolant loss Volvo V70 tdi - adverse camber
We have a 99 V70 tdi (the old vw 5 cylinder diesel).

We keep getting coolant loss, but its irregular. The car will be fine for ages then suddenly lose maybe a pint of coolant. There are no obvious leaks anywhere. hoses seem OK. In about 18months I have had to top it up 4 times. I keep an eye on the level regularly and it seems constant, but then (and its always on a morning) we start it and the warning light is on. Sure enough we are down again. I checked the level on Friday - fine. This morning, low.

All I can think is that the cap on the expansion tank might be playing up? It is the later green one (I know early V70's had a problem with the caps). Is there a suitable dye (like the A/C dye) that can be stuck in the coolant - or should antifreeze show up under uv anyway?

thanks

Dealer should be able to do a system pressure check.

Having become an expert on this (Office hack days), worth checking or even replacing without checking the cap on the expansion tank. It looks innocent enough but can be faulty !
