Assenmacher GM245 Fuel Injector Seals Tool

Used for replacing the fuel injector Teflon seals on General Motors 2.0L & 3.6L engines with Hitachi fuel injectors (2010-2017) and 2.0L,2.4L, 2.5L, 5.3L & 6.2L engines with Bosch, Continental & Delphi fuel injectors (2012-2017)/ Also used on Subaru (2014-2019) 2.0L/2.4L turbo engines.

Comparable to EN-49245, EN-49245-SUB, EN-51105 & 18683AA000

The Hitachi SIDI system used on 2010-2012 LF1 3.6L V6 and LAF 2.0L ECOTEC has 2 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 their bores in the cylinder head.

  • There are two seal installation pilots included in AST GM245 (one for each groove) which allow the seal to slide onto the injector tip without catching on any machined surface, or the incorrect groove.
  • AST GM 245 also 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 and ensure its size prior to installation.
  • AST GM245 must be used to install the seals correctly and to ensure they are sized correctly for leak-free operation.
