Start the engine, and allow the engine to idle for 2 minutes. In order for this test to run, the vehicle must operate in the following conditions:
    • Acceleration at part throttle to 50 MPH with this speed maintained until the engine reaches operating temperature. This may be up to 8-10 minutes depending on the start up coolant temperature.
    • Continue the operating conditions for an additional 3 minutes after the engine reaches operating temperature.
