Hi All 
.
As I suggested on my MK1 thread, I have been working on the MK2 Turbo. Its been loosing coolant, even after paying a local garage to fix it. Due to the state they left my UT in after the last visit, I decided never to use them ever again (or go back to let them finish the job as they requested).
So, A colleague was kind enough to lend me his coolant pressure testing kit. It works by increasing the pressure on a cold system. In essence, it’s an air pump and a pressure gauge which attaches to the radiator expansion / header tank. You pump to increase the pressure of the air gap at the top of the coolant, thus increasing the pressure on the whole system.
This simulates what happens at full operating temperature. The difference is that water will be pushed out of any hole in liquid form, not steam, allowing you to locate the smallest of leakleaks when steam may not be visable (if its external).
Unfortunately, the borrowed tester is past its best. I couldn’t get it to seal. My colleague outlined that there is another way to do this, which I’ll share with you
