Before ordering

- Complete number on the existing part and any replacement/supersession reference.
- Installed pump number, drive arrangement and impeller dimensions.
RP061017 serves the listed belt/crank-driven pump assemblies. The serpentine pump uses RP061022; do not interchange by engine size alone.

Fitment & setup
Will this work on a serpentine-belt engine?
This listing specifically excludes serpentine-belt applications and points to RP061022 as the alternative reference. Confirm the pump on your engine with GT40 before ordering either part.
What should I send to confirm the impeller?
Send the engine identification, pump label, belt/drive arrangement and current impeller number. The listing references PCM GM 5.0L, 5.7L and 7.4L applications through 2004, but the actual pump must match.
