  Q: How to replace the fuel injector and ensure proper installation of O-ring seals on Cadillac DTS?

  A: The first step to replace a Fuel Injector entails removing the Fuel Rail before taking out both the Fuel Injector Fuel Rail clip and the injector itself. You should dispose of existing o-ring seals positioned above and below the part. When inserting new o-rings they should be correctly positioned to prevent fires and fuel leak-related personal injuries so place blue o-rings on the upper position while black o-rings should go on the lower position because both seals share similar dimensions but come from disparate materials. Replacements of Fuel Injector o-ring seals should happen during all servicing sessions because implementing the accurate seal prevents driveability problems and vacuum leak occurrences. The new o-ring seals receive engine oil lubrication before you install them onto the Fuel Injector as upper and lower components. After placement of the Fuel Injector inside the Fuel Rail you need to use the Fuel Injector Fuel Rail clip to fasten it followed by reinstalling the Fuel Rail.
