6. Fan

(1)  Check the cooling fan operation with low temperature (Lower than

83°C)

 (a) Turn the ignition switch to “ON” position.

 (b) Check that the cooling fan stops.

 (c) Pull out the water temperature sensor connector. See (Figure

122)

 (d) Connect the water temperature sensor to car body with the

wire and ground the wire.

 (e) Check the cooling fan operation.

 (f) Insert water temperature sensor connector.

> 93°C

See (Figure 123)

 (a) Start engine and make the coolant temp. higher than 93°C.

 (b) Check that the cooling fan turns.

Replace it with water temperature switch if it doesn't run)

(3) Check the cooling fan. See (Figure 124)

 (a) Disconnect the cooling fan connector.

 (b) Connect the battery and ammeter to the connector.

 (c) Check that the cooling fan rotates smoothly and check

the reading on the ammeter.

Standard amperage: 5.7 - 7.7A

 (d) Reconnect the cooling fan connector.
