Maintaining your vehicle’s cooling system is essential to prolonging the life and efficiency of your engine. The coolant system dissipates engine heat into the ambient air in order to prevent overheating and to keep your vehicle running safely. A coolant flush and fill is basic maintenance for your cooling system, and will help ensure maximum performance from your car’s heating and cooling systems.

Let’s take a look at your cooling system and what you can do to ensure it keeps
running smoothly.

Properly balanced mix of water and antifreeze that circulates throughout your engine to draw off heat.
Primary component of your engine’s cooling system, its purpose is to help remove heat from the engine. It relies on the water pump to help circulate the engine coolant through its core so it can release excess heat that has been absorbed by the engine coolant in the engine block.
Located between the engine and the radiator, the thermostat opens and closes. It’s function is to block the flow of coolant into the engine until the engine has warmed up to operating temperature.
Water Pump
The heart of your cooling system, the water pump circulates the engine coolant throughout the entire cooling system.
Works with the thermostatic switch or engine computer to turn on when the temperature of the coolant goes above a set point to help cool down your radiator and prevent overheating

Check your car owner’s manual to see the recommended interval for changing your antifreeze and flushing your coolant system. New antifreeze will help your car’s engine run cooler, and flushing it will remove any dirt, rust or sediment which may damage the water pump and clog your engine water jacket and radiator.

If you’re a do-it-yourselfer, be sure to always follow the instructions for maintenance listed in your owner’s manual. Dispose of used antifreeze according to your local laws and regulations. Use a closed container to store it, and never let used antifreeze drain onto the ground or into storm drains.

Consider using a flush solution which can remove much more sediment and rust than normal water alone. Ask your local Pep Boys sales associate to help you find the best flush solution and antifreeze for your car.
