Hello supramania people. Recently my car has been being well a bit of a bitch. I got the car last year and it had some overheating issues not a problem. Last year while driving the water pump went, so I replaced it and it now this year I went up to a car meet at Pocono Raceway and while driving noticed that the temp gauge was higher than it should be, so now I'm not in a good mood and I'm thinking the head gasket is starting to go. My uncle suggested I pressure test the radiator before doing anything. Is there a specific cap that I'd need for a tester or is it just a standard cap. What general pressure should it hold too? I've never had to do this before.
