- With transmission in neutral or park and parking brake set, start engine and allow to reach normal operating temperature.CAUTION: Position the pressure gauge so that the air blast emitted will be harmlessly dissipated.
- Slowly increase engine speed to 1000 RPM and observe pressure produced at pressure gauge. The air pressure must be 2 1/4 psi minimum.
- If pressure gauge is not available, run engine at 1500 RPM and place hand over open end of hose. Air flow should be felt and heard.
- If air flow does not meet specifications, replace air pump assembly and repeat test.
