I have a MEP004A Generator. I need to know what is the operating pressure for the radiator cap. Right now is not releasing the pressure and the radiator panel covers are going to explode... any suggestion?????

Three or four lbs. should be plenty You should be able to run the engine with the cap loose. If not your radiator could be plugged. The water pump trying to push water through can bulge things, the faster the engine runs the badder it is.
