FAQ

Which engines is this water pump compatible with?
Detroit Diesel 53 series — 3-53, 4-53, 6V53, and 8V53.

How do I confirm the correct rotation?
When viewed from the front, right-hand rotation turns clockwise. If your engine rotates counterclockwise, use the left-hand version.

What does the arrow shown in photo 1 indicate?
The arrow indicates the pulley’s position on the left side of the water pump housing. This configuration confirms the water pump is a right-hand model.

Can I use this on a left-hand engine?
No. Installing a pump with the wrong rotation may cause reverse coolant flow and overheating.

Is it new or rebuilt?
This is a new OEM-quality pump with new bearings, seals, and impeller.

Does it include the mounting gasket?
The gasket is sold separately. Always use a new gasket when installing.
