Header Tank cap - does it look right?
Posted: 26 Apr 2009, 21:17
My header tank was leaking and huge clouds of steam billowing up when the water spilt onto the exhaust. When I removed the header tank cap, one of the two valves fell off (the hole in the cap on the left in the photo). So I bought a new one, but the valve arrangement look totally different. Is this right?

[BTW, the broken valve in the cap wasn't actually the cause of the problem - that was the coolant level sensor which had cracked where it screws into the header tank! But it might explain why the expansion tank was always empty...]
