Frequently Asked Questions

Q: Why is coolant dripping out of the little weep hole on my engine case?
A: A dripping weep hole is the classic warning sign that your internal mechanical water pump seal has failed. Replacing the old seal with this premium Vertex kit will isolate your cooling jacket and stop the leak completely.

Q: Does this kit require using the original water pump shaft?
A: Yes, this kit includes all the consumable wear parts like bearings, gaskets, and seals. You will reuse your existing water pump shaft and impeller, provided they are not excessively grooved or damaged.

Q: Should I clean the internal housing before installing the new seals?
A: Absolutely. Make sure the water pump bore and shaft are completely clean and free of scale, old gasket residue, or corrosion before installing the fresh components to ensure a flawless seal.

Expert Pro-Tip: When pressing in the new mechanical water pump seal, never press directly on the inner carbon ring or spring surface, as doing so can easily fracture the delicate sealing element. Use a socket or installer tool that matches the outer metal flange of the seal body only. Also, check your old water pump shaft for deep grooving where the old seals rode; if you can catch your fingernail in a groove on the shaft, replace the shaft along with this kit to avoid premature seal failure.
