Frequently Asked Questions

Q: What's the difference between two-piece and one-piece water pumps?
A: Two-piece pumps have a separate cover housing that mounts between the pump and engine block. This design allows for easier servicing and is standard on earlier diesel engines. One-piece pumps have an integral housing cast as part of the pump body.

Q: Can I upgrade from a two-piece to one-piece pump?
A: Yes, one-piece pumps (16100-09260) are compatible with all engine vintages when replacing both the pump and cover housing assembly.
