INNTECK Oversized Water Pump Kit for KTM EXC 450, EXC 520, EXC 525, SX 450, SX 520, SX 525 and BETA RR 525 1999-2009

The INNTECK 16-2080 water pump kit is designed for KTM EXC 450, EXC 520, EXC 525, SX 450, SX 520, SX 525 and BETA RR 525 from 1999 to 2009. The water pump circulates the coolant between the engine and the radiators. A performance water pump kit replaces stock parts to increase coolant flow: the engine gets rid of its heat better when it's working hard.

Specifications

• Brand: INNTECK
• Manufacturer part number: 16-2080

When do you need it?

The kit is specific to each engine: check the bike and years. The exact contents are given in the specifications; have new gaskets ready if they aren't included.

Fitting tips

1. With the engine cold, drain the coolant.
2. Remove the pump cover and, if the kit includes an impeller, the stock impeller, following the manual.
3. Check the pump shaft and its seals: at the slightest play or weeping, fit a water pump rebuild kit.
4. Fit the kit parts with new gaskets and tighten the cover bolts in a crisscross pattern, to the torque in the manual.
5. Refill with coolant, bleed the air and check for leaks.

Frequently asked questions

Does the kit lower the temperature?
It increases coolant circulation; the gain depends on the bike, the terrain and the condition of the radiators. Clean radiators and fresh coolant are still essential.

Are the gaskets included?
It depends on the kit: check the specifications and, if needed, add a water pump rebuild kit.
