Fitting Pistons

  1. With piston assembly removed, remove piston rings and clean piston. Measure piston outer diameter in thrust direction, below oil ring groove. Diameter is 2.793-2.794" (70.954-70.974 mm) for 1.3L engines and 3.0690-3.0698 (77.954-77.974) for 1.6L engines.
  2. Place piston upside down in cylinder from which it was removed. Using a feeler gauge, measure clearance between piston and cylinder bore. If clearance is not within specification, bore cylinder and replace piston as necessary. See CYLINDER BLOCK  table in ENGINE SPECIFICATIONS at end of article.
