2003 Buick Park Avenue Parts Questions & Experts Answers

• Q: How to replace the engine flywheel on 2003 Buick Park Avenue?

  A: It is essential to begin Flywheel replacement by extracting the transaxle before removing eight bolts between the Crankshaft flange and Flywheel to preserve the bolts for disposal. Check the Crankshaft mating surfaces on the Flywheel for burrs before inspecting them. One must evaluate as well as clean the engine Flywheel before placing it into service. The correct procedure for Flywheel installation requires new bolts to which you must apply torque at 15 nm with a torque angle meter (J 36660-A) before advancing the bolts by 50 degrees. To perform the Flywheel runout measurement, use the dial indicator set (J 8001) on the engine block while maintaining Crankshaft end-play in one direction at the three attaching bosses. A Flywheel runout above 0.381 mm (0.015 inch) calls for correcting it by tapping with a mallet against the high spot but replacement of the Flywheel should happen when runout cannot be fixed successfully. Finally, reinstall the transaxle.
