WARNING: This page is about a different car, the 2003 Acura 3.2TL, 2002 Acura 3.2TL, 2001 Acura 3.2TL, 2000 Acura 3.2TL, and 1999 Acura 3.2TL. However, it is still accessible from the selected car via links, so may be relevant.

Remove the piston from the cylinder block. See CRANKSHAFT & PISTON .

NOTE: Take care not to damage the ring grooves.

Apply engine oil to the piston pin snap rings (A) and turn them in the ring grooves until the end gaps are lined up with the cutouts in the piston pin bores (B). See Fig 1.
Remove both snap rings (A). Start at the cutout in the piston pin bore. Remove the snap rings carefully so they do not go flying or get lost. See Fig 2. Wear eye protection.
Heat the piston and connecting rod assembly to about 158°F (70°C), then remove the piston pin. See Fig 3.
