Understanding Coolant and Why It’s Essential for Engine Protection

Coolant (also known as antifreeze) regulates your engine’s temperature by absorbing heat and preventing freezing, boiling, and corrosion throughout the cooling system.
Over time, coolant can become contaminated, lose effectiveness, or leak due to worn components.

This MAP educational video explains how coolant works, what causes coolant-related problems, and why regular maintenance is essential to protect your engine.

At the Motorist Assurance Program (MAP), we provide drivers with clear, unbiased information about essential vehicle systems.

By understanding how coolant supports safe engine operation and recognizing signs of deterioration, motorists can make informed decisions when discussing cooling system maintenance with a professional.

Common signs of coolant issues include overheating, visible leaks, low coolant levels, sweet odors, fluctuating temperature readings, or a “Check Engine” light.

Because these symptoms can also be linked to radiator problems, water pump failure, thermostat issues, or hose deterioration, proper diagnostic testing is crucial to identify the root cause.

After watching this video, consider consulting a MAP-qualified service facility if your vehicle shows signs of cooling system trouble.
