1. Check the temperature of inlet hose and outlet hose of heater core.
2. Check that the inlet side of heater core is hot and the outlet side is slightly lower than/almost equal to the
inlet side.
CAUTION:
Always perform the temperature inspection in a short period of time because the engine coolant
temperature is very hot.
Is the inspection result normal?
YES >> GO TO 9.
NO >> Replace the heater core after performing the procedures after the cooling system inspection. GO
TO 1.
9.REPLACE HEATER CORE
Replace the heater core. Refer to heater core. Refer to VTL-43, "
Exploded View".
Are the malfunction solved?
YES >> END.
NO >> Perform the procedures again after the cooling system inspection. GO TO 1.

3. Set the vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.
4. Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if
steering wheel is not in the neutral position.
STEERING WHEEL TURNING FORCE
1. Park the vehicle on a level and dry surface, set parking brake.
2. Tires need to be inflated normal pressure. Refer to WT-5, "
Tire Air Pressure".
3. Start the engine.
4. Bring power steering fluid up to adequate operating temperature.Standard
