An Overview of your Vehicle's Cooling System from your Ohio's Experts

A vehicle's heating system is often one that is frequently used around this time a year, but is often taken for granted as a luxury in modern vehicle components. Like your engine oil, your antifreeze should be flushed according to your mileage, but not as frequently as changing your oil. This service, as well as others can be done at any local Bob Sumerel Tire location! There are many parts that work together to make this cooling system operate fluidly, getting the engine up to operating temperature. Below are brief descriptions of each of these components, and what their responsibilities are within the vehicle:

• Thermostat - Typically on the top of the motor, this small valve opens when the engine reaches operating temperatures to allow coolant to pass into the engine. This component is also in charge of creating warm air in the car's cabin when you turn the heat on.
• Water pump - This cast iron piece is run by a pulley system from your serpentine belt, pumping the water in and out of the motor.
• Radiator - This part is located in the front of the vehicle, it regulates the temperature of the pressurized coolant that cycles in and out of the motor. 
• Expansion Tank - Also known as an overflow tank, this plastic container is what you pour your coolant into, which holds any excess coolant.
• Hoses - There is an upper and a lower hose, both are in charge or distributing coolant to different parts of the motor, also cycling it through the radiator. These hoses should be free of any cracks or bulges at the ends.  
• Cooling fan - Usually located on the radiator, or attached to the water pump pulley this component is in charge of cooling the vehicle's radiator. 
• Coolant/Antifreeze- This fluid is essentially the "blood" of your car's cooling system. It is a 50/50 mixture of coolant and water that keeps your car's motor from freezing over or boiling up when in operation. 

Failure to flush your coolant system can cause severe calcium build up within the internal parts of your cooling system. Calcium build up can deteriorate plastic radiator parts, as well as cast iron parts engine parts, and even rubber gasket material. These individual components should be visually inspected about every oil change to ensure there are no leaks in the system. Call your local Bob Sumerel Tire shop if you have any questions about your vehicle's suggested fluid intervals.
