2004 Cadillac Seville Fuel Injector Parts Questions & Experts Answers

• Q: How to replace a fuel injector and ensure proper installation of the 0-rings on 2004 Cadillac Seville?

  A: The replacement of the Fuel Injector requires users to first remove the Fuel Rail and push the locking tab facing the center to separate the Fuel Injector. Start by removing top and bottom 0-ring seals from your Fuel Injector but dispose of the worn-out injector 0-ring seals. Install the new 0-rings following their proper orientation for fuel leak prevention by placing blue-colored material in the upper position and black material in the lower position even though both rings are identical in size. The use of proper part numbers is essential when buying fuel injectors along with regular replacement of 0-rings during service in order to avoid driveability problems caused by vacuum leaks. Apply clean engine oil to both new upper and lower 0-rings then install them onto the Fuel Injector for its reattachment to the Fuel Rail.
