The Hitachi SIDI system, used on 2010-2012 LF1 3.6L V6 and LAF 2.0L ECOTEC engines, features two seals in the injector tip. These seals must be installed into their grooves and then sized to the engineered dimension before the injectors are installed into the cylinder head bores.

The EN-49245 kit includes two seal installation pilots (one for each groove) to ensure the seal slides onto the injector tip without catching on any machined surface or incorrect groove. Additionally, the GM-49245 kit includes a seal installer to drive the seal over the pilot and into the groove, and a sizer to compress each seal into its groove, ensuring proper sizing for leak-free operation.

For 2013 and newer injectors from Bosch, Continental, and Delphi, which have slightly larger injector tips, the protector ramps from the GM-51105 Injector Seal Installer Adapter set are required. These ramps are used with the installer and sizer from the GM-49245 kit.
