Re: Radiator Fan Constantly On
Check the cooling fan relays and water temperature switch, and check for a separated connector or severed wire between the cooling fan relay and water temperature switch.
Water Temperature Switch - on water inlet housing. (a) Using an ohmmeter, check that there is no continuity between the terminal and body when the coolant temperature is above 93°C (199°F). (b) Check that there is continuity between the terminal and body when the coolant temperature is below 83°C (181 °F). If continuity is not as specified, replace the switch. Cooling Fan Relay (”FAN NO.1 ”) - in box by battery A. Inspect relay continuity Terminals 1 and 2 are horizontal pointing at one another. Terminals 3 and 4 are parallel to each other pointing at terminals 1 and 2. (a) Using an ohmmeter, check that there is continuity between terminals 1 and 2. (b) Check that there is continuity between terminals 3 and 4. If continuity is not as specified, replace the relay.
