What’s the Importance of My Car’s Cooling System?

Your car’s cooling system keeps your engine, radiator, and you at a comfortable temperature while driving. In addition, flushing your radiator’s old antifreeze and filling it with new antifreeze helps protect your car’s engine from overheating. Other aspects of cooling system maintenance include checking these things:

  • Radiator coolant levels

  • Radiator for leaking antifreeze

  • Air conditioner’s interior vent temperature

  • Heating and cooling system controls

  • Inspecting all hoses

  • Cooling system pressure cap

  • Checking the thermostat

  • Water pump belt inspection

How Often Should I Service My Car’s Cooling System?

Our expert technicians at Ray’s OK Service recommend that you have your cooling system inspected for service professionally at least once a year. Flushing the old antifreeze from the radiator and adding new antifreeze is a basic and regular form of maintenance that increases the life of your engine. It prevents against overheating, freezing, and corrosion of the engine. 

Our mechanics can also identify any problems in the cooling system that may need repair or replacement as well. It’s a good idea to bring your car in when you notice problems of any kind, but especially if you suspect an overheating engine.
