The radiator is essential for the cooling of combustion engines. In such engines, there may be as many as 3,000 petrol explosions per minute, each generating temperatures of up to 1,300°C. The cooling liquid, which is circulating through a cooling jacket, cools the engine block, as well as pistons, valves, gaskets, rings, engine head, and other elements of the engine. Through the radiator, it exchanges the heat with atmospheric air.

Highly competitive product range of +2976 models in range covering +15,900 OE numbers and almost the entire European,US and Asian vehicle car park. H&Q radiators are submitted to corrosion, vibration, pressure impulse, thermal expansion and thermal performance tests.
