ALL CHEVROLET DEALERS
Some water pump pulleys on the above listed 1985 vehicles, equipped with 6.2L diesel engines and air conditioning may
experience a crack in the area where the pulley is bolted to the water pump flange.
To correct this condition, a new water pump pulley, P/N 15550089, is available. The new pulley contains a reinforcing cup located
on the outside of the pulley hub.
Because it is thicker than the pulley it replaced, this new pulley requires longer mounting studs. Four new studs are included with
the pulley, and it is MANDATORY that all four studs are installed with the new pulley to assure proper clamp load.
This new pulley can be used on either VIN Code C or J engines and is currently available through WDDGM.
