Radiator Cooling Fan: Service and Repair

HYDRAULIC COOLING FAN SYSTEM BLEEDING

1. CHECK FLUID LEVEL IN RESERVOIR TANK
- If low, add fluid: ATF DEXRON II

HINT: Check that fluid level is within the HOT level on reservoir tank. If the fluid is cold, check that it is within the "COLD" level on the reservoir tank


2. BLEED COOLING SYSTEM





(a) Using SST, connect terminals OP1 and E1 of the DLC1 - SST 09843-18020

HINT: When terminals OP1 and E1 are connected, the circuit of the ECT sensor is grounded, fixing the cooling fan speed at approx. 1,100 rpm. (Fail-safe operation occurs.)

(b) Start the engine without depressing the accelerator pedal.
(c) Leave the engine running for several seconds.





(d) Check that there is no foaming and emulsification of the fluid in the reservoir tank.
(e) Remove the SST from the DLC1. SST 09843-18020
