Mysterious Coolent Leak T5 2006

[sanj]

There is one test you have not performed!

A cooling system pressure test.

I have one as I'm sure Tim does too. We would be able to pressurise your cooling system with the engine off up to about 15psi. Then and only then will you be able to look for coolant leaks, listen for hissing noise of maybe a split hose or leak somewhere and watch the needle on the gauge to see if it drops (indicating a blatant leak).

I did say Cooling system pressure test....not chucking oil down your cylinder bores, which is not the same thing. That is a cylinder Compression check!
Just doing a sniffer test is only half the checks and only tells you that there is no combustion gases present in the cooling system, which there shouldn't be.

it would be great if you could pressure test the cooling system for me, I have been looking into it but the kits are bit pricey, how would we go about arranging that..?

cheers
