i changed thermostat 2x's just in case i brought bad one (test out okay). i've taken the water pump off -inspected it ( no leaks at weep hole;no noise;feels tight as to no excessive play;) i reinstall water pump - hoping for no leaks!! why should i suspect head gaskets- no steaming from tail pipe;no water in oil;no oil in radiator;vehicle runs with no missing or skipping when temperature is normal - runs terrible only when over heating. how about clutch fan - ????
