Cooling Radiators

To keep the engine cooling systems in optimum condition, radiators need to work efficiently.

How radiators work

To keep the engine running efficiently, it needs to be at an optimum temperature. The cooling radiator plays a key part in the engine cooling system, Engine heat is absorbed by the coolant, circulating in the cooling system. The radiator releases this heat to the atmosphere, by using the air flow, while the vehicle is moving. When a vehicle is stationary, the (electric) cooling fan(s) support heat transfer by pulling or pushing air through the radiator. To take advantage of the air flow as the vehicle moves, the radiator is installed at the front of the vehicle. The radiator needs to have the right cooling capacity as the heat exchange (air flow) can be affected by other heat exchangers, such as the condenser, oil cooler or intercooler.

To perform this function effectively, the radiator needs to be powerful and well-designed. DENSO has worked with engine cooling experts to ensure our components can run effectively even in the most challenging environmental conditions.

Types and characteristics

To ensure efficient cooling performance, it is crucial to select the right type of cooling radiator for the right vehicle application.

Cooling Radiators types

Down flow type

Coolant flow is from top to bottom.
Down flow radiators are ussually taller and require more space

Cross flow type

Coolant flow is from right to left in this example. Cross flow radiators are lower, with the same cooling capacity as down flow radiators.


Our cooling radiators have been designed to deliver optimum performance within a smaller, more efficient component design.

Fault finding

Improper radiator operation can result in a car’s engine overheating. Should this occur, the driver should immediately stop the vehicle to prevent costly engine damage. Call road assistance and have the vehicle checked and if needed, recovered to a workshop for repair.
