FAQs

Will this kit work on all motorcycle models?

No, the WPK-18DM is designed for specific motorcycle models. Always verify compatibility with your bike's year and model before purchase.

Do I need special tools for installation?

You will need basic hand tools and a torque wrench, along with the necessary coolant for your specific motorcycle.

What is cavitation and how does this kit fix it?

Cavitation is the formation of air bubbles in the coolant which inhibits heat transfer. The Nautilus impeller design smooths the flow of liquid, reducing these bubbles.

Can I reuse my old water pump gasket?

It is highly recommended to use a new gasket or O-ring during installation to ensure a leak-free seal.

Does this replace the radiator?

No, the Supercooler replaces the water pump impeller and cover, not the radiators themselves.

Troubleshooting

Coolant leaking from the pump area after installation

Verify that all O-rings are seated correctly and the housing bolts are torqued to the manufacturer's specification.

Engine continues to run hot

Ensure that the cooling system was properly bled of all air pockets and check the radiator fins for obstructions.

Pros and Cons

Pros

  • Significantly improved coolant flow compared to stock components
  • Reduces engine operating temperatures during demanding conditions
  • Minimizes cavitation for more consistent cooling
  • High-quality construction designed for off-road durability

Cons

  • Requires complete draining and refilling of the cooling system
  • Installation necessitates specific mechanical knowledge
  • May require replacing stock gaskets or seals depending on the bike's age

Setup, Compatibility & Care

Installation of the WPK-18DM involves removing the right-side engine cover to access the water pump cavity. Always drain the radiator fluid completely before beginning the installation. Ensure that you use a high-quality coolant compatible with your engine manufacturer's specifications. During assembly, check all O-rings and gaskets to ensure a proper seal to prevent leaks. Maintenance of this kit is minimal; however, it is recommended to inspect the impeller and housing for any debris during your regular seasonal cooling system flush.
