Piston and Connecting Rod Assemblies

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The pistons are cast aluminum with a flat top design. Piston skirts are coated to reduce friction. Each piston uses 2 compression rings and 1 3-piece oil control ring assembly. The piston pin is a full-floating design and is retained to the connecting rod by clips located in each end of the piston pin bore. The connecting rod and rod cap are positioned and aligned by a dowel pin and retained by bolts.
