Four Seasons Engine Cooling Fan Controller,Engine Cooling Fan Controller-Universal P/N:35879
Four Seasons 37504 relay for the 1984-1988 Ford Tempo and other vehicles is the radiator fan controller relay, the part that switches power to the cooling fan.
A radiator fan that stays off, or a temperature gauge that climbs while you sit in traffic, can mean this relay is failing. A blown fuse, a worn fan motor or a damaged connector can show the same signs, so find the cause before buying a new relay.
It is listed for a wide range of Ford and Mercury models, including the 1984-1988 Mercury Topaz and the 1984-1987 Ford Escort. If your car isn't named here, look it up in the "Vehicles it fits" section.
Will this work as a 1984-1987 Ford Escort relay?
Yes. Four Seasons 37504 is listed for the 1984-1987 Ford Escort and the 1984-1988 Ford Tempo. For any other car, look it up in the "Vehicles it fits" section.
What kind of connectors does the Four Seasons 37504 relay have?
Four Seasons 37504 has OE style molded connectors.
Are the contacts in this radiator fan controller relay built for good conductivity?
Yes. This relay has quality contacts that are made to give proper conductivity through the fan circuit.
What signs can a failing radiator fan relay show?
A cooling fan that never starts, an engine that runs hot when stopped, or a temperature gauge that climbs in traffic can all be signs. A shop can test the fan circuit.
Is this radiator fan controller relay a universal part?
No. It is made for vehicle specific applications, so it is matched to the cars it is listed for rather than sold as a universal relay.
