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.
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.
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.
