  Q: How to replace the fuel injectors on 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.

  Q: How to service and repair the fuel injector on Chevrolet Trailblazer?

  A:

  Start by disconnecting the Fuel Rail assembly but ensure no damage happens to the pin or the nozzle of the Fuel Injector then refrain from placing the electrical component in any cleaner because doing so could harm it. The Fuel Injector leak can cause engine oil to mix with fuel during the service and repair procedures. Separate the Fuel Injector harness connector before removing the retainer clip and extracting the Fuel Injector out from the Fuel Rail while discarding both the retainer clip and injector o-ring seals (2, 4) from both sides of the injector. Check the application when getting new fuel injectors because the Fuel Injector assembly displays a part number identification together with a four-digit build date code which shows the manufacturing month, day, year, and shift. The installation begins with cleaned engine oil on new injector o-ring seals (2, 4) before placing them on the injector followed by new retainer clip installation on the injector. Complete the install by inserting the Fuel Injector into the Fuel Rail injector socket with the retaining clip locked onto a flange on the socket while maintaining the electrical connector facing outward.
