Pulsair Valve: Testing and Inspection

PULSAIR VALVE

1. Inspect pulsair valve and hoses for leaks and cracks. Replace as necessary.
2. Disconnect pulsair hose from valve fitting. On V6 engines, both Pulsair valves must be tested individually.
3. Disconnect pulsair solenoid from valve, if equipped.
4. Connect a suitable hand held vacuum pump to valve and apply a minimum of 15 inches of vacuum to valve. Time vacuum loss from 15 inches to 5 inches of mercury. If vacuum drops in less than two seconds, replace pulsair valve.
