Water Pump - Removal

WARNING: This page is about a different car, the 2002 Pontiac Sunfire and 2002 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

Tools Required: J 36008-A  Camshaft Timing Pins

Important:  The timing chain tensioner must be removed to unload chain tension before the water pump is removed. If the tension is not unloaded, the water pump will become cocked in the timing chain housing and the water pump will be difficult to remove.

  1. Rotate the timing chain sprockets to line up the holes. Install the J 36008-A  .
  2. Remove the bolts holding the tensioner in place.
