2008 Chevrolet Express 3500 Fuel Injector Parts Questions & Experts Answers

• Q: How to replace the fuel injectors on 2008 Chevrolet Express 3500?

  A: You must take off the Fuel Rail initially after that open the Fuel Injector retainer clip to remove the Fuel Injector. The replacement procedure involves both removing the injector retainer clip and discarding the Fuel Injector O-Ring seals at their second and fourth positions. The denso fuel injectors for 5.3l (L59) e85 applications do not separate o-ring and retaining clip maintenance so replacement must happen every time you update an o-ring or replace a clip. Therefore select your correct injectors during ordering. Fuel injectors will show two distinct coded information: a part number stamp followed by a four-digit production date marking which includes month, day, year and manufacturing shift information. Clean engine oil must be used to lubricate the new Fuel Injector O-Ring seals (2, 4) before their installation onto the Fuel Injector. New retainer clips receive attachment to the Fuel Injector before the Fuel Injector enters the Fuel Rail injector socket around the flange where the clip locks securely. Position the electrical connector toward the outside as you install the Fuel Injector . Finally, reinstall the Fuel Rail.
