Fitting Pistons
WARNING: This page is about a different car, the 2001 Ford ZX2 and 2000 Ford ZX2. However, it is still accessible from the selected car via links, so may be relevant.
To determine if piston-to-cylinder clearance is within specification, measure piston skirt diameter at 90-degree angle to piston pin. Measure piston diameter 1.62" (42 mm) from top of piston. See PISTONS, PINS & RINGS table under ENGINE SPECIFICATIONS. Oversize pistons are available in .010" (.25 mm) and .020" (.50 mm).
