Piston - Selection
WARNING: This page is about a different car, the 2002 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The cylinder bore must be within the specifications for taper and out- of- round before fitting a piston.
- Select a piston size based on the cylinder bore.
- Choose the piston with the correct grade size.
- See 3.0L V6 VIN S or 3.9L VIN A .
NOTE:
For precision fit, new pistons are divided into three categories within each size range based on their relative position within the range. A number on the new pistons indicates the position within the size range.
