Rod, Piston And Connecting: Description
WARNING: This page is about a different car, the 2018 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Do not use a metal stamp to mark connecting rods as damage may result, instead use ink or a scratch awl.
The pistons are made of a high-strength aluminum alloy. Piston skirts are coated with a solid lubricant (Molykote) to reduce friction and provide scuff resistance. The piston top ring groove and land is anodized. The connecting rods are made of forged powdered metal with a "fractured cap" design. A floating piston pin is used to attach the piston and connecting rod.
