January 8, 2004My engine has been doing something with the coolant ever since the heater hose blew out and leaked everywhere. I had that fixed and all taken care of however, I cannot keep coolant in the overflow box. Everytime I take it somewhere they top it off and occasionally I do this at my house. It has been about 2.5 years since it all leaked out. It doesnt leak anywhere or smell, doesnt seem like its getting into the exhaust either. Any Ideas!?!?!?
