That's exactly what is bothering me. I put on a new cap this morning, and drove to work. After several hours of cooling off, I pulled the cap and it still had quite a bit of pressure underneath it, but maybe not as much as before. Unfortunately, I think some of the pressure may be allowed to relieve itself through a weak spot in the radiator, because there is yet another leak formed under the truck, coming from the radiator. <img src="/forums/images/graemlins/angry.gif" alt="" /> <img src="/forums/images/graemlins/angry.gif" alt="" />

Darin- I did pull the plugs on Saturday to look at them, and none where exceptionally clean. There was one whose insulator was a bit whiter than the others, but not enough to make me really take note of it at the time.

A lot of my hoses are swelling up like crazy--- I'm just waiting for another one to blow. <img src="/forums/images/graemlins/frown.gif" alt="" /> I may have to start tearing into it tonight or tomorrow night.
