• For GM / General Motors. The camshafts on the ECOTEC engines must be held when removing or installing the cam phaser bolts, or the timing chain may slip and not keep its relationship to the phasers. A1774 mounts to the front of the block and its tabs engage both cam phasers to hold them so the phaser bolts may be serviced. A pass-through hole on each side allows a socket to be used to remove or install the phaser bolt. Current service methods use an open end wrench to hold the cam, and can be very awkward, especially for in-vehicle service.
• Application: Ecotec/2010 Buick LaCrosse, 2010 Chevrolet Equinox, 2010 GMC Terrain, 2.0L, 2.4L ECOTEC engines
