Holes Added To Water Pump Impeller{1361}
Usage:
3204, 3208 Engines In All Applications
Two holes have been added in the water pump impeller for all 3204 and 3208 Engines. The holes permit increased coolant flow around the water seal assembly in the pump. The result is a longer service life for the seal assembly.
Holes can be added to earlier impellers as shown in the illustration.
Locations of the holes.
