Koyorad Radiator | External Oil Cooler
The radiator dissipates heat from the engine coolant by passing it through a matrix of tubes and fins exposed to airflow, maintaining the engine within its safe operating temperature range. Signs of a failing radiator include: an engine that overheats, visible green or orange coolant leaking from the radiator core or tank, a damaged plastic end tank, or internal deposits visible when the cap is removed. Replace a leaking or damaged radiator before overheating causes engine damage.
