Shop Discount Radiators

The function of a car’s radiator is to act as a heat exchanger. Essentially, it is designed to cool the hot liquid that is inside of it by using the airflow that passes over it to remove the heat. Radiators are specifically built to facilitate this process. Inside the radiator are a series of thin tubes surrounded by cooling fins. These fins are usually made out of a material that conducts heat well, like aluminum. The coolant in the tubes transfers some of its heat to the very thin fins, and these fins in turn pass off their heat to the air rushing by them. The part of the radiator the contains the tubing and the cooling fins is called the radiator core. It is usually sandwiched between two coolant tanks, either one on each side or one on top and one on the bottom. These tanks have hoses attached to them, with one tank bringing coolant into the radiator from the engine and the other pushing it back out of the radiator into the motor. Radiator tanks also have a filling cap that allows you to add more coolant to the system if it is running low. In order to cool most efficiently, the entire system is under pressure. It is very important to never remove the radiator cap from your vehicle while it running, or if the temperature gauge is above cold. Doing so will cause extremely hot pressurized liquid to shoot out rapidly, and this could serious scald or otherwise injure you.
