2004 Lincoln Aviator AWDFACTORY OEM SERVICE PROCEDURE

Upper Intake Manifold: Notes

  1. Disconnect the battery ground cable.
    2. WARNING: Never remove the pressure relief cap under any conditions while the engine is operating. Failure to follow these instructions could result in damage to the cooling system or engine or personal injury. To avoid having scalding hot coolant or steam blow out of the cooling system or reservoir, use extreme care when removing the pressure relief cap from a hot cooling system or reservoir. Wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it slowly until the pressure begins to release. Step back while the pressure is released from the cooling system. When certain all pressure has been released, remove the pressure cap (still with a cloth).
