2009 Chevrolet Trailblazer Parts Questions & Experts Answers

• Q: How to replace the fuel injectors on 2009 Chevrolet Trailblazer?

  A: Before installing new fuel injectors personnel need to break apart the Fuel Rail assembly. Remove the Fuel Injector electrical harness connectors from their positions on the fuel injectors and remove the fuelprecioretainer clips. Extract the fuel injectors from the Fuel Rail while disposing of the retained clips and remove them from the Fuel Rail assembly. Discard all o-ring seals from the ends of the injectors (3,5) by removing them. Check the selection of new fuel injectors to find the correct model since the Fuel Injector assembly shows both its part number and a four-digit manufacturing date that includes the month and day of production and the manufacturing shift. Apply clean engine oil to both new injector o-ring seals (2, 4) before installing them onto the injector. Implement a new retainer clip onto the injector while pushing fuel injectors into the Fuel Rail until the electrical connector faces outward with the clip securing to the Fuel Rail injector socket flange. Use the remaining steps to join the Fuel Injector electrical harness connectors to the fuel injectors before installing the Fuel Rail assembly.
