2005 Cadillac DeVille Parts Questions & Experts Answers

• Q: How to replace a fuel injector on 2005 Cadillac DeVille?

  A: First detach the Fuel Injector after moving the locking tab on the Fuel Rail toward the center and setting aside the Fuel Rail. The first step requires removing both the lower and upper o-ring seals from the injector until you need to discard them. The correct placement of new o-rings requires attention to avoid fuel leakage risks and fire hazards and personal injuries; put the blue o-ring on top when they have different black and blue coloration. The correct part number must accompany all replacement Fuel Injector orders while o-ring replacement at each injector servicing interval helps avoid leaks that cause driveability problems. After lubricating the new o-rings with engine oil, install them on the Fuel Injector followed by clamp retention of the Fuel Injector onto the Fuel Rail and subsequent reinstallation of the Fuel Rail.
