Below, you’ll find answers to the following:

  • What is antifreeze?
  • Are coolant and antifreeze the same liquid?

  • Why is antifreeze important?

Facts About Antifreeze

First, let’s answer the question: Is antifreeze coolant? Yes! “Coolant” and “antifreeze” are just two names for the same fluid. You might think that coolant keeps the engine cool or that antifreeze prevents freezing, but in reality, they regulate the temperature of the engine in any weather condition.  Coolant is made from ethylene glycol or propylene glycol. Appearance-wise, it’s orange, pink, or green, depending on its ingredients. Green engine coolant is most common, but your vehicle may require a different grade, based on the model and how it’s driven. The easiest way to check is to read your owner’s manual or to contact one of the service technicians at Mercedes-Benz of West Covina for advice.

What is Antifreeze Used for?

The coolant reservoir is located under the hood, which is where coolant is stored. It’s pumped through the engine via the water pump, and absorbs heat as it travels. Once heated, the coolant travels to the radiator, where it cools down. After it’s had time to cool, it’s recirculated through the engine, repeating the same process. Needless to say, antifreeze is absolutely essential to your engine’s health — almost in the same way oil is.

Why is Antifreeze So Important?

Coolant doesn’t just keep your engine operating efficiently; it also promotes safer driving on La Puenta roads. Its properties also make it resistant to below-freezing temperatures. Running your vehicle’s engine without coolant can have disastrous results, particularly for the following parts:

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

If your car’s hood is hot to the touch or there’s steam coming from under the hood, schedule a service appointment as soon as possible. There could be an issue with your coolant levels, causing engine overheating.
