2008 Cadillac CTS Fuel Injector Parts and Q&A

• Q: What tools are required to replace the fuel injectors with Direct Fuel Injection (LLT) on 2008 Cadillac CTS?

  A: The tool collection for direct fuel injection (LLT) Fuel Injector replacement includes en-47909 injector bore and sleeve cleaning kit together with en-48266 injector seal installer and sizer, j 2619-01 slide hammer, and j-37281-a injector remover. Lowering the fuel system pressure on the high side should be the first step. First detach the fuel injection Fuel Rail assembly and afterward discard the Fuel Injector hold down clamp and separate the wiring harness from the injectors. Direct fuel injectors must be extracted using the tools j 2619-01 and j-37281-a. You must throw away the injectors' upper o-ring seal in addition to their plastic spacer and retaining ring and isolator cup and teflon seal. The installation requires new o-ring seal gm p/n 12345610 or canadian p/n 993193 which needs silicon-free engine oil lubrication before fitting upper o-ring seal, plastic spacer, retaining ring, isolator cup, and teflon seal onto the components. The en-48266-1 tool should be placed against the injector tip before applying a new seal on it and drawing the seal down the injector's groove. Apply the en-48266-2 to the seal for resizing until it reaches the bottom of the injector body while you rotate it 180 degrees clockwise then counterclockwise. The en-48266-2 tool must be removed before placing the new direct fuel injectors into the cylinder head through the use of fresh hold down clamps together with harness wire connections. Mount back the fuel injection Fuel Rail assembly as the last step.
