Fast Idle Thermo Valve: Testing and Inspection
NOTE: The fast idle thermo valve is factory adjusted; it should not be disassembled.
1. Start the engine.
2. Remove the hose from pipe. Put your finger over the pipe and check for air flow (vacuum with the engine cold (engine coolant temperature below
86°F (30°C) and idling.
^
If no vacuum is felt, replace the fast idle thermo valve and retest.
4. Warm up the engine (the radiator fan comes on).
5. Check that the valve is completely closed. If not, air suction can be felt in the valve pipe.
^
If any suction is felt, the valve is leaking. Check engine coolant level and for air in the engine coolant system. If OK, replace the fast idle
thermo valve and recheck.
