Most all-terrain vehicle (ATV) engines are typically liquid-cooled. The coolant is cooled by moving through an ATV radiator while air flowing through the radiator removes the unwanted heat.

OEM MPN's: 1240721,1240527,1240720

The ATV radiator is tucked into the vehicle's frame, just ahead of the engine to both protect from damage as well as to position it to receive the optimum flow of air.

OEM MPN's: 1240721,1240527,1240720

To maintain a cool temperature of the coolant and the engine, there is usually an electric fan mounted behind the ATV radiator to draw air through when the machine is idling, which is running while sitting still.

NICHE Radiator

  • An ATV radiator usually includes an aluminum core made up of cooling tubes and cooling fins combined with plastic tanks that work to cool the engine of a machine.
  • The aluminum core is the area of the radiator that the coolant flows through.
  • Small aluminum strips called cooling fins, aid in absorbing the heat from the coolant.
  • As the air passes over these fins and makes its way through the radiator, the heat dissipates back into the atmosphere.
  • The cooling efficiency of a radiator can be increased by adding more rows of cooling tubes to the core.

Identical to the old one, good price, and quick shipping.

Not sure about the reviews who said this radiator doesn't work. Worked fine for me. Perfect fit for the model listed.

This radiator flows in and right back out on the left side. It’s not separated between the inlet and outlet to make the coolant flow across the fins and back around to the other outlet.It only heats up on the inlet and outlet side.
