Piston 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.

General Equipment- Micrometer

NOTE: Mark piston in case a piston has to be again installed.

Using a Micrometer measure the piston in two directions.
- Measure the piston diameter at the height of the piston pin bore, but offset by 90 degrees.
