What Are the Functions of a Car Radiator?

Car Radiator - hybrid suvWhether you're driving a brand new hybrid SUV, a classic muscle car or conservative family sedan, one piece of equipment all will certainly have installed is a radiator. Radiators are appliances designed to transfer heat, whether in your automobile or in your home.
Vehicle radiators perform two important functions:
  • Cooling the engine
  • Providing heat for the passenger cabin

Proper Cooling is Critical

Explosions and friction associated with internal combustion engines cause the engine to heat up significantly. This is needed because an engine must "warm up" and remain at proper operating temperature for best performance. Too much heat, however, will destroy your vehicle's engine, causing metal parts to fuse and the engine to seize.

Channels built into an engine's exterior allow for cooling fluid to run through the unit, transferring heat from the engine to the coolant. The liquid then runs through a hose to the radiator, where heat is dissipated to the surrounding air, facilitated by the radiator's fins, the engine fan, and the radiator's front-positioning within the engine compartment.

Fin-construction allows for maximum surface area and small tubes running through the radiator expose the coolant to the effects of cooler surrounding air. It's then returned to the engine jacket in order to absorb more heat. During this cyclic process, some of the heat is made available to the passenger compartment, where it's used to provide warmth for occupant comfort.

Your car's thermostat is a heat-sensitive valve that regulates when and if coolant is circulated through the system. This regulates engine temperature. A low coolant level in your hybrid SUV or your two-seater sports car can spell disaster if allowed to go too low. Then it's new engine time!
