Frequently Asked Questions

Q: Is the mechanical seal included in this kit?
A: Yes, this kit includes the mechanical water pump seal, along with all other necessary bearings and gaskets required for a full rebuild.

Q: How often should I rebuild my water pump?
A: It is generally recommended to inspect your water pump seals whenever you are performing major engine maintenance or if you notice coolant weeping from the weep hole on the side cover.

Expert Pro-Tip: When installing the new mechanical seal, keep it absolutely clean. Fingerprints or any tiny spec of dirt can cause the seal to leak prematurely. Use a clean, appropriately sized driver to press it in squarely—never tap directly on the ceramic sealing surface, or you will crack it and it will leak immediately.
