Cooling System Service & Inspection in Mt. Pleasant, MI

In order for your vehicle’s engine to perform at its best, its cooling system needs to be functioning properly. Your vehicle’s regulator (part of your cooling system) is responsible for regulating the amount of heat in your vehicle’s engine. If the regulator is too cold, it emits more pollutants and engine components can wear out prematurely. If the regulator is too hot, the engine can overheat and sustain serious damage or even fail completely. Coolant (also known as antifreeze) serves two critical functions: it keeps the engine from overheating in the summer, and freezing in the winter. Coolant is made up of ethylene glycol and water – a mixture that raises the boiling point and lowers the freezing point. Corrosion inhibitors, found in the mixture, help protect the metallic cooling system components as well.

To keep your engine functioning as it should, we recommend changing your traditional coolant every 24,000 miles or two years. However, other coolants on the market are designed to last longer. If you aren’t sure what kind of coolant you have in your vehicle, or you’re concerned about your cooling system not working correctly, bring it into either of our Hank Graff Service Center locations in Mt. Pleasant.
