Testing the electric cooling fans applies for Honda Civic 1992-1995.
Coolant Temperature Switch
- Remove coolant temperature switch (located on rear of engine block). Suspend temperature switch and thermometer in a container with a 50/50 mixture of coolant and water. DO NOT allow thermometer or temperature switch to touch bottom of container. Heat coolant mixture.
- Check continuity between temperature switch terminals. With coolant temperature 181-191°F (83-91°C), continuity should not exist. With coolant temperature 191-203°F (91-95°C), continuity should be present.
Fan Motor
Unplug 2-pin connector from fan motor. Connect battery power to either fan motor terminal. Connect ground to other fan motor terminal. Replace motor if it fails to run.
Relays
- Remove radiator and condenser fan relays. Radiator fan relay is located on right front inner fender and condenser fan relay is located on left front inner fender (if equipped).
- Connect positive battery power to relay terminal “C” and connect terminal “D” to ground. For terminal identification, see wiring diagrams . Continuity should be present between relay terminals “A” and “B”. No continuity should be present when battery power is disconnected.
