Fitting Pistons

WARNING: This page is about a different car, the 2003 Saturn Vue and 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

Measure diameter of piston at a 90 degree angle to piston pin, 9/16" (14.5 mm) from bottom of piston. Measure diameter of cylinder at 90 degree increments at 1/2" (13 mm) from top of cylinder bore and at 4" (100 mm) from top of cylinder bore. If oil clearance exceeds specification, bore cylinders and replace pistons with oversize pistons. If cylinder bores are out-of-round or have excessive taper, hone or bore cylinders as necessary. See PISTONS, PINS & RINGS  and CYLINDER BLOCK  tables under ENGINE SPECIFICATIONS.
