• Q: How to replace the fuel injector on 2005 Buick Terraza?

  A: The procedure for Fuel Injector replacement starts with removing the Fuel Rail and continuing with removal of the Fuel Injector retaining clip followed by extracting the Fuel Injector from the Fuel Rail. You should carefully take off the upper o-ring and lower o-ring from the injector without damaging electrical connector pins or nozzles while you must avoid placing the injector in any cleaner for protection against potential damage. The new injector must carry proper part number identification stamps to enable purchasing correct replacements. Clean engine oil should be used to lubricate the new o-rings (2, 4) before installing the upper o-ring first then the lower o-ring second. You should first slide the Fuel Injector into the Fuel Rail before using the retaining clip to fasten it and installing the rail.
