cooling system pressure tester.

About an inch out of the header tank every week or two...

When you notice the header tank level has dropped, is it by the same amount each time?

The heater is disconnected and there are no damp patches!
I have now tried the test with a fairly hot engine with the same results, no real pressure drop.
Not sure what's going on so I will keep on trucking until something else happens.

How much water are you losing?

Check for a damp footwell carpet and if you have a rear heater have a look at the hoses going up into the heater matrix.
I added some uv dye to my coolant so leak tracing is easy

OK I've had a go with the tester now although I didn't have the correct rad cap adapter I just held it on, put 15 PSI in and it held pressure ok, only lost about 1 PSI over a few minutes, I will also try it hot later......

I've just bought a Sykes Pickavant cooling system pressure tester to try and find where my coolent Is going. Looks like a very nice piece of kit, I'll post the results once I've had a go with it.
