The cooling system uses a pressurized forced-circulation system with an open air type reservoir tank.
A thermostat with a bypass valve is located on the water inlet housing to maintain suitable temperature distribution in the cooling system.
An aluminum radiator core is used for weight reduction.
A 3-stage linear temperature-controlled fluid coupling assembly is used.
Toyota Genuine Super Long Life Coolant (SLLC) is used.
A water-cooled engine oil cooler is used.
