Alright, just lately my temp guage is getting really hot, almost 3/4 when it usually never passes 1/4. Also there is steam blowing out of my overflow tube causing it to bubble and overflow to the ground and then after the engine is cool the overflow resivior is completely empty. It isn't constantly getting hot, it has only happened three times and that was after i got on it a little bit. There is no smoke coming from the exhaust and my stock hg is torqued to 85 ft lbs on a jdm engine with ~50,000mi. Could this be my water pump or a small leak in the radiator or somewhere? Or is it the dreaded BHG?
