COOLING SYSTEM

Power is supplied to the fan via the Orange/Black wire

when the relay is energized. The brown wire provides a

ground path for the fan motor. Refer to "RELAYS" later in

this chapter for more information on fan functions.

Keep hands away from fan blades during operation.

Serious personal injury could result.

The fan may not function or operation may be delayed if

coolant level is low or if air is trapped in the cooling

system. Be sure cooling system is full and purged of air.

Refer to Chapter 2 "Maintenance" for cooling system

information.

1. Disconnect harness from the engine coolant

temperature sensor located in the cylinder head of

2. With the vehicle in park, turn the key on. After a few

seconds, you should hear the cooling fan turn on and

remain running.

3. If the fan does not run or runs slowly, check the fan

motor wiring, wire connections, ground path, 12V

power input, and fan motor condition. Repair or

replace as necessary. If the fan runs while the engine

is running with the sensor harness disconnected, but

will not turn on when the engine is hot, verify the

coolant level is correct and check the coolant

temperature sensor and connector terminals.
