WARNING: This page is about a different car, the 2002 Acura MDX and 2001 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
  1. Apply engine oil to piston pin snap rings. Turn snap rings in grooves until end gaps line up with cutouts in pin bores. Carefully remove snap rings.
  2. Heat piston and rod assembly to approximately 158°F (70°C), then remove piston pin. Allow components to return to room temperature.
  3. Using a micrometer, measure piston pin diameter. Zero a dial indicator to piston pin diameter. Use dial indicator to check difference between piston pin diameter and piston pin hole diameter. Measure pin-to-connecting rod clearance. If any component measurement is outside service limits, replace as necessary. See PISTONS, PINS & RINGS  table under ENGINE SPECIFICATIONS.
  4. Install one piston pin snap ring. Coat pin bore in piston and connecting rod with engine oil. Heat piston to approximately 158°F (70°C). Install piston pin. Assemble piston and connecting rod with embossed marks on same side. Install remaining snap ring.
