Before I installed the high output water pump, it did overheat with the gauge going all the way to H while driving, and the engine starting to run rough. Radiator and hoses were very hot, and lots of pressure and steam in the radiator. I will try the idle test you suggest next. If coolant does blow out, will that be through the overflow tube or through the cap?
