.
CIRCUIT OPERATION
The fan control module is powered from fusible link number 2. The PCM judges the required revolution speed of radiator fan motor and
condenser fan motor using the input signals transmitted from A/C switch,
automatic compressor controller, vehicle speed sensor and engine coolant
temperature sensor. The PCM activates the fan control module to drive the
radiator fan motor and condenser fan motor.

1. Check that the coolant level is up to the filler neck. Install a radiator tester and
apply 160 kPa (23 psi) pressure, and then check for leakage from the radiator
hose or connections.
burned by hot coolant.
CAUTION:
Be sure to completely clean away any moisture
from the places checked. When the tester is taken out, be careful not to
spill any coolant. Be careful when installing and removing the
tester and when testing not to deform the filler
neck of the radiator.

RADIATOR CAP PRESSURE CHECK 1. Use a cap adapter to attach the cap to the tester.
2. Increase the pressure until the indicator of the gauge stops moving.

3. Replace the radiator cap if the reading does not remain at or above the limit.
ENGINE COOLANT REPLACEMENT 1. Drain the water from the radiator, heater core and engine after unplugging the
radiator drain plug and removing the radiator cap.
2. Drain the water in the water jacket by unplugging the drain plug of the cylinder
block. For the right bank side on AWD vehicles, drain the engine coolant from
the water feed tube assembly of the transfer box.
3. Remove the radiator condenser tank assembly and drain the coolant.
4. Drain the coolant then clean the path of the coolant by injecting water into the
radiator from the radiator cap area.
WARNING:When removing the radiator cap, use care to avoid
contact with hot coolant or steam. Place a shop
towel over the cap and turn the cap
counterclockwise a little to let the pressure escape
through the vinyl tube. After relieving the steam
pressure, remove the cap by slowly turning it
counterclockwise.
