Hydraulic Cooling Fan Fluid Reservoir: Testing and Inspection
ON-VEHICLE INSPECTION FLUID LEVEL INSPECTION1. KEEP VEHICLE LEVEL
2. INSPECT FLUID LEVEL
(a) Using SST, connect terminals OP1 and E1 of the check connector.
SST 09843-18020
(b) Keep the engine speed at 2,000 rpm until the fluid temperature reaches the specified temperature. Fluid temperature:
70-90°C (158-195°F)
(c) Check that there is no foaming and emulsification of the fluid in the reservoir tank.
(d) Measure the fluid level with the engine running.
(e) Stop the engine, and measure the fluid level.
(f) Subtract (d) from (e).
Maximum stroke: 5 mm (0.20 in.)
(g) Check the fluid level. If low, add fluid.
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 tank.
(h) Remove the SST from the check connector. SST 09843-19020
HYDRAULIC COOLING FAN SYSTEM BLEEDING
1. CHECK FLUID LEVEL IN RESERVOIR TANK If low, add fluid.
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 tank.
2. BLEED COOLING SYSTEM
(a) Using SST, connect terminals OP1 and E1 of the check connector.
SST 09843-18020
(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.
