Air Relief Valve

  1. Warm engine to normal operating temperature. Disconnect hose from air relief valve. Ensure no air flows from hose. If air does flow, air relief valve may be stuck open.
  2. Disconnect electrical connector from relief valve solenoid No. 1. Using jumper wires, energize solenoid. If air flows from air relief valve, air relief valve and relief valve solenoid No. 1 are okay. See Figure . If air does not flow, check vacuum routing, relief valve solenoid No. 1, air pump and air control valve.
