93 metro cooling fan

[dwendt1978]

I just purchased a 1993 geo metro xfi for 400.00 and the front was smashed a bit but I bought it because the frame wasn't rusted at all. But the problem is when I was looking under the hood there was no radiator fan. Is this normal? Car doesn't overheat or anything but if it needs one what side does it go on and how hard is it to install? Thanks for your help. Great site.

Is it normal?....NO!. The radiator cooling fan mounts in front of the radiator (Facing the engine), and is controlled (Turned ON/OFF) by the "coolant fan thermostat switch". When it kicks on, it draws heat off the radiator and blows air into the engine bay at the same time until the temp falls below 199 Degrees. Then the fan turns OFF. My guess is that due to the front end accident, the fan was damaged and never replaced. In Hot weather, the car will eventually overheat if sitting in traffic etc.....Not good for these 3 cyl geo motors! I'd go to a junkyard and find the fan motor mounting bracket and fan motor assembly from a wrecked Geo metro. The electrical connector for the cooling fan will be round, and just behind the DS Headlight area....... Here's the info you'll need:

Description and Operation

RADIATOR FAN CONTROL
Fan Activation
When the ignition switch is in the "ON" position, system voltage is applied through the IG Fuse to the fan thermostat switch. The fan thermostat switch closes when engine coolant temperature reaches 98°C (208°F). With the fan thermostat switch closed, voltage is applied to the coil side of the radiator fan relay. Since the radiator fan relay is permanently grounded at G101, the contacts close and voltage is applied through Fusible Link B to the radiator fan motor. The radiator fan motor is permanently grounded at G102 and will continue to operate as long as the fan thermostat switch remains closed.

Fan Off
When the engine temperature falls below 93°C (199°F), the fan thermostat switch opens, and voltage to the coil side of the radiator fan relay is interrupted, the contacts open and the radiator fan motor stops.



Radiator Fan: Service and Repair

Disconnect battery ground cable.
Drain cooling system and disconnect upper radiator hose from radiator.
Disconnect fan motor electrical connector.
Raise and support vehicle, then remove one lower mounting bolt from fan shroud.
Lower vehicle and remove two upper cooling fan mounting bolts, then remove fan from vehicle.
Reverse procedure to install.

Thanks a bunch. Found it right away. Ordered one on ebay for 55.00 and I'll be good to go in a couple days.
