I am not sure if the radiator fan is working on my 92 v6 camry its not over heating but never see or hear the fan running is there a fuse or relay that might have gone out. I cant even see any wires that go to it. Thank you Tony

The radiator fan in the 92-95 models of V-6 Toyota and Lexus vehicles is a weird design. The fan is not electric but runs off the power steering pump. The power steering pump moves fluid through hoses to the radiator fan, thereby creating its rotation. A sensor monitors coolant temperature and signals a solenoid on the power steering pump when more or less cooling is needed. The power steering pump then speeds up or slows down to provide more or less fan speed.

This system seems to work pretty well. However, there is a connector that goes to the power steering pump that is critical to proper operation. In engine work this connector often gets overlooked when reassembly is done. This results in the fan running at constant speed and not increasing rotation when more cooling is needed. This becomes a problem primarily when the car is idling or moving at a slow speed.

If your car is not overheating in these situations, the fan is probably operating okay.

In this wheather it may never need to come on best thing to test would be pop your hood shut off the heater and let it run for15-20 min to see if it comes on because they usually dont come on unless your in traffic on a hot sunny day.the radiator usually gets enough cold air to it by driving down the road to keep the engine cool and the fan is set to come on at a certain temperature and go off once the temp drops
