What is Antifreeze?

So, is antifreeze coolant? Yes, it is. Antifreeze, or coolant, is a liquid added to your car’s radiator to regulate the temperature of the engine. This liquid is responsible for protecting your car from freezing and overheating during your Sheboygan commute.

Composed of ethylene glycol or propylene glycol, antifreeze varies in color, but typically it will be green, pink, or orange. Green is the most common color, but you should always check your car’s manual to guarantee you are using the correct antifreeze for the make and model of your vehicle. Even though antifreeze is crucial for your car, it is toxic, and spills should always be cleaned up to keep pets and children safe.

What is Antifreeze Used for?

Now that you know what antifreeze is, what is antifreeze used for? Stored in the radiator and connected by a reservoir in the engine bay, antifreeze is circulated throughout your engine by the water pump, which pulls combustion-generated heat away from your engine. The antifreeze, now heated, flows back into the radiator, where it is cooled by air. This process happens continuously as you drive through West Bend, keeping your engine at a safe temperature.

Why is Antifreeze Important?

Engineered to keep your engine from overheating in the summer and freezing in the winter, antifreeze is vital. Without antifreeze pumping through your engine, several areas of your car’s engine would be critically damaged, including:

  • Water Pump 
  • Engine Cylinders
  • Connector Rods
  • Head Gasket
