Piston Pin Diameter

WARNING: This page is about a different car, the 2002 Mercury Cougar. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The piston and piston pin are a matched pair. Do not mix up the components.

Measure the piston pin diameter.
- Measure the diameter in two directions.
- If the values are not to specification, install a new piston and a new piston pin.
