The other week i was driving on the inerstate and suddenly my car started overheating. the serpentine belt had broke and the water pump pulley had seized. the car had overheated before i could get off the road. towed the car home, replaced the water pump, noticed the thermostat housing had a hairline crack in it so went ahead and replaced the thermostat, housing and temp sensor. also replaced the fan clutch while front end was off. i flushed the radiator once. after putting it all back together, it is still wanting to over heat. what else could be the problem? please help as this is my daily driver

Radiator? How old is it? After the drain/refill, are u positive coolant is topped off? With the ENGINE COLD, remove rad cap to check coolant level.

radiator is original, i believe. so 20 years old. i topped off the coolant all the way, but dont know if i burped the system all the way. going to reflush in the morning, and try to burp again.

Quite possible that no amount of flushing will remove build-up from a 20 year old rad. If it continues to overheat, consider replacing it, it's the last item not replaced.....hot months just around the corner.

if you do it yourself you will see and feel the weight difference!!!! (between the old one taken out and the new one to be put in.)
