2008 Cadillac DTS Parts Questions & Experts Answers

• Q: How to replace a fuel injector on 2008 Cadillac DTS?

  A: The Fuel Rail needs removal before starting Fuel Injector replacement. After you remove the Fuel Injector Fuel Rail clip you can take out the Fuel Injector. The Fuel Injector repair requires users to dispose of existing upper and lower o-ring seals. There are safety constraints when installing new o-rings to prevent fuel leaks and personal injuries because of the following steps: if the o-rings display a black and blue color difference, put the blue o-ring in the upper space and position the black o-ring below because both parts share equivalent dimensions yet contain dissimilar materials. The replacement of the Fuel Injector o-ring seal must happen during injector servicing since it serves as a crucial preventive measure against vacuum leaks and driveability problems. Insert clean engine oil on both new o-ring seals before installing them correctly to the Fuel Injector's upper and lower positions. Secure the Fuel Injector into place by attaching its Fuel Rail clip and then re-install the Fuel Rail. Use only the designated part number for buying new fuel injectors.
