My 1999 chevy venture is running really hot. Temperature gauge goes almost into the red after 3-4miles of city driving and im adding a qt of antifreeze/water every couple days. No noticeable radiator leaks, no water or smoke from the tailpipe, and only cool air when the heat is on full blast. Im gonna add gasket sealant tomorrow hoping that fixes the problem. Is that a smart move?
