Why do they have to be qualified? All the operator has to do is find the right size attachment for the radiator, start the car, then sit back and see if the testing fluid changes colour. -- Brad

The one I visited recently had an MTA(?) license sign on the wall, a couple actually, and one said "Cooling Specialist", think the other said something about Air Conditioning. -- Brad

At work, we used to get the car up to heat, with the cap off, light a cig-lighter at the filler-neck. If the leak was substantial, you'd see some small flames as the fuel/air bubbled out. Jason

A radiator specialist is one who has the tool for the TK test and only specialises in heating/cooling issues for your engine. Just as there are Air Conditioning experts, Auto electricians, Automatic specialists etc. Not all mechanics have the equipment and certainly one well known "hothead" retired mechanic in here had never heard of a TK test before do you believe?
