With your vehicle, it is important to keep it properly maintained. This should also include being aware of any issue you notice between visits. The radiator is a part that is vital to the operation of your vehicle. The main function of the radiator is to dissipate the excess heat generated by the engine as it burns fuel. It functions as a component of the larger cooling system. As engine coolant moves through the radiator, it goes through the intake, cooling, and outlet.

The engine’s water pump produces a flow of coolant that runs in a specific direction into and out of the radiator. The amount of coolant that moves through the radiator is controlled by the thermostat, which opens and closes according to the temperature of the engine. Once the flow of engine coolant moves past the thermostat, it enters the radiator through the upper hose.

Once the coolant enters the first tank, it flows into tiny passages that connect the two tanks. These small passages are connected to rows of fine metal fins, which are what give the radiator its distinct ribbed appearance. The metal fins are usually made of either copper or aluminum. Air is forced through the spaces in between these fins and the heat is dispersed away from the engine in the form of hot air. This process keeps heat from building up in your engine, preventing overheating.

Once the engine coolant has moved through the cooling passages, it is collected in another tank on the other side of the radiator which stores the coolant until it is taken into the outlet hose. The radiator’s outlet hose connects the radiator to the water pump and it supplies the low-temperature coolant to the engine as needed.

If you start to notice an issue with your vehicle overheating or the radiator, make sure to schedule an appointment with us so we can inspect the vehicle for you.
