Understanding Radiators and Their Importance in Engine Cooling

The radiator plays a key role in your vehicle’s cooling system by dispersing heat from the engine through coolant and airflow. When the radiator becomes clogged, corroded, or damaged, it can lead to overheating, coolant loss, and reduced engine performance.

This MAP educational video explains how radiators work, common causes of failure, and why regular inspections are essential for maintaining a reliable cooling system.

At the Motorist Assurance Program (MAP), we aim to provide motorists with clear, unbiased information to help them understand important vehicle systems.

By learning how the radiator supports safe engine operation and recognizing signs of trouble, drivers can make informed decisions when discussing maintenance or repair needs with a service professional.

Typical symptoms of radiator issues include overheating, coolant leaks, discolored coolant, low coolant levels, or visible corrosion on the radiator.

Because these signs may also indicate problems with the water pump, thermostat, or radiator hoses, accurate diagnostic testing is crucial to determine the correct repair.

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