92 Honda Accord, Cooling Fans Not Working
Q: I am writing because we just replaced a radiator in our '92 Honda Accord DX. For some reason the cooling fans will not come on. We are worried that this is the sign of another problem. We made sure when we replaced it that we bled the air out but no matter how much we drive it the fans will not come on. Is this a problem? Please help.

A: The cooling fans must be functional or you will damage the engine. If the cooling fans were working prior to changing the radiator then it's likely that there is an electrical connection problem or the coolant temperature sensor for the cooling fans has failed. There's a temperature sensor mounted in the radiator, usually in area of the lower radiator hose on Honda's, that controls the cooling fans. With older vehicles it is not uncommon to have some corrosion buildup at this coolant temperature sensor's terminals. Disturbing the electrical connectors will sometimes cause them not to make a good contact when re-connected. Also double check the electrical connectors for the cooling fans. Usually a little cleaning is all that is needed to get the cooling fans working again.
