• Q: How to replace the fuel injectors on 2010 Cadillac CTS?

  A: Starting the replacement process the fuel injectors require releasing pressure from the high side of the fuel system first. Record the exact positioning of the injectors which you will use during installation. You need to remove the Fuel Rail assembly of the fuel injection system and discard the three rings used for retaining the fuel injectors. Pull out the direct fuel injectors together with their harnesses as one unit and detach the electrical connector. Apply the j 2619-01 (slide hammer) with j-37281-a (injector remover) for equal removal of the injectors when necessary. Separate the upper o-ring seal combined with the plastic spacer and retaining ring and isolator cup and teflon seal from the fuel injectors. The cleanup procedure for Fuel Rail injector bores uses j-39313 (spark plug port adapter) alongside en-47909 (injector bore and sleeve cleaning kit) and requires inspection before starting this task. Install new Fuel Injector components by applying engine oil to an o-ring seal before adding the upper o-ring seal together with plastic spacer and retaining ring and isolator cup and teflon seal. Install en-48266 (injector seal installer and sizer) with its accessory en 48266-1 into the injector tip without applying oil to the new teflon seal component. Insert the new teflon seal into the groove on the injector by running it through the en 48266-1. Place the en 48266-1 at the injector tip followed by en 48266-2 installation before using en 48266-2 to resize the teflon seal through gentle application of force. Follow the sequence of removing the en 48266-2 before installing the direct fuel injectors with their harness as a single unit while reconnecting the electrical connector. The conclusion of this procedure consists of reattaching the fuel injection Fuel Rail assembly.
