Note. Do not use a caustic cleaning solution or a wire brush to clean the pistons or damage can occur.

Scheme 2049

Scheme 2050

1. Clean and inspect the (1) ring lands, (2) skirts, (3) pin bosses and the (4) tops of the pistons. If wear marks, scores or glazing is found on the piston skirt, check for a bent or twisted connecting rod.
2. Use the Piston Ring Groove Scraper to clean the piston ring grooves. Make sure the oil ring holes are clean.

SPECIAL TOOL(S) SPECIFICATION Feeler Gauge Set 303-D027 (D81L-4201-A) or equivalent

Note. Use care when fitting piston rings to avoid possible damage to the piston ring or the cylinder bore.

Note. Piston rings should not be transferred from one piston to another.

Note. Refer to the appropriate ENGINE - 3.5L GTDI or ENGINE - 3.7L for the specification.

Note. The cylinder bore must be within specification for taper and out-of-round.

Scheme 2051

Scheme 2052

1. Use a piston without rings to push a piston ring in a cylinder to the bottom of ring travel.
2. Use the Feeler Gauge Set to measure the top piston ring end gap and the second piston ring end gap.

SPECIAL TOOL(S) SPECIFICATION Feeler Gauge Set 303-D027 (D81L-4201-A) or equivalent

Note. Refer to the appropriate ENGINE - 3.5L GTDI or ENGINE - 3.7L for the specification.

Scheme 2053

Scheme 2054

1. Inspect the piston for ring land damage or accelerated wear.
2. Using the Feeler Gauge Set, measure the piston ring-to-groove clearance.
