Car radiator is a main part in auto cooling system and car engine, which function is to dissipate heat. The cooling water absorb heat in the water jacket, disperse heat after flowing to the radiator, then back to the water jacket and the cycle continues, achieving the effect of thermoregulation.

Oil cooler is a device that accelerates cooling of lubrication oil to keep a relatively low temperature.

Relay is an automatically controlled device when the input (electricity, magnetism, sound, light, heat) reaches a certain value, a dramatic transition of output will occur. Auto relays has large switching and good impact and vibration resistance.

Exhaust pipe is installed between the engine exhaust manifold and muffler, making the entire exhaust system a flexible coupling, thus making it easier for vibration and noise reduction, easy installation and prolonging the life of the exhaust muffler system.
