THERMACTOR II Pulse Air System: Testing
- With engine off, inspect hoses from pulse air valves to air cleaner for cracks, splits, etc. Inspect clamps and connections for tightness. Replace as necessary.
- Disconnect hose from air inlet valve to air cleaner at valve Connect Thermactor Air Valve Tester (T75L-9487) to the open end of air valve. Position hose clamp and tighten securely.
- Squeeze test bulb on tester to force as much air from bulb as possible. Quickly release bulb and note the time it takes for bulb to return to its normal shape.
- Bulb should remain collapsed for at least 15 seconds. If bulb returns to its normal shape in less than 15 seconds, air inlet valve is defective and should be replaced.
