Removal Procedure

  1. Raise the vehicle.
  2. Caution: Provide additional support when a vehicle is on a hoist in the following ways:

       • Before removing parts, support the opposite end. This helps prevent the vehicle from slipping off.
       • Before removing major components, chain the vehicle frame to the hoist pads at the same end as the removal. This helps avoid a tip-off.
    Failure to follow these precautions could cause vehicle damage, serious personal injury, or death.

  3. Disconnect the electrical connector.
  4. Remove the fuel pump and the engine oil pressure indicator switch.
