How to Change the Fuel Filter on a 2005 Rendezvous

by Kyle McBride

Buick equipped the 2005 Rendezvous with an in-line fuel filter between the gas tank and the engine to remove scale and dirt from the gas before it reaches the precision components of the fuel-delivery system. Quick-connect fittings on the fuel filter and hoses allow for replacement of the filter with little difficulty. There is no service interval for the filter. Replace it when the collected debris inside the filter restricts fuel flow.

Turn the ignition key to the "Off" position. Turn off all electrical accessories. Set the parking brake.

Don safety glasses. Open the hood and disconnect the battery's negative cable with a wrench.

Unscrew the cap on the fuel-pressure port by hand. The cap is located on the fuel rail. Screw the fuel-pressure gauge fitting onto the fuel-pressure port. Wrap a shop rag around the fitting and connect the fuel-pressure gauge to the fitting.

Insert the gauge's bleed hose into the fuel container. Open the valve on the gauge slowly. Fuel released with the pressure drains into the fuel container.

Close the valve once the pressure is relieved and fuel stops draining into the container. Remove the gauge, the fitting and the shop rag. Screw the cap onto the fuel port.

Jack up the front of the car with the jack and support it with jack stands.

Position the drain pan under the fuel filter which is mounted on the frame forward of the gas tank. The fuel filter is a small, cylindrical, metal canister with a hose connected to each end. Blow dirt and debris from the filter and fittings with compressed air.

Squeeze the tabs on the hose fittings on either end of the filter. Pull the connector off the filter in-pipe fitting. Repeat on the other fitting. Catch any remaining fuel in the drain pan.

Remove the nut on the fuel-filter bracket with a wrench. Remove the fuel filter.

Install the new fuel filter into the stud. Install and tighten the bracket nut to 89 pound-inches with a torque wrench.

Apply a few drops of engine oil onto the ends of the filter's in-pipe fitting. Connect the hoses to the filter. Press the connectors on the hoses onto the fittings until they snap into place, then pull them as if to pull them off. The connectors should remain securely snapped and not come off.

Remove the drain pan. Remove the jack stands and lower the vehicle to the ground. Connect the battery's negative cable.

Turn the ignition key to the "On" position for two seconds, then turn it to the "Off" position for 10 seconds. Turn the ignition key to the "On" position and check for fuel leaks.

Warnings

  • Never get under a car or allow anyone else to get under a car that is supported only by the jack. Always use jack stands for safety.
  • A few drops of engine oil applied to the in-pipe fittings of the filter are necessary to ensure proper reconnection and prevent possible fuel leaks. O-rings in the connector may not seat properly if not lubricated.
  • If any part of the procedure seems beyond your capabilities, consult a qualified mechanic before proceeding.
