Re: pressure test radiator

Why do u need to pressure test it??? It is NOT a pressurised cooling system. If u're looking for leaks then just fill up the radiator with some water annd let it set for a week and watch for leaks.

There is not much point to pressure testing ANY radiator for that matter. It either flows well (see Owen Dyneto post above) and doesn't leak.

U can pressure test it all day long. But once installed and HEATED up bythe engine and subject to road vibrations it sould leak where a static pressure test would indicate no leaks.

The pressure test is usualy done on FULLY ASSEMBLED cars. Usuaaaly to find leaks in head gaskets or other places of the cooling system whereit might be otherwise difficult to locate the precise point of leakage.
