How Does a Car Radiator Work?

by Joe Ferguson on August 29, 2013


The radiator in your car serves an absolutely vital function. A car radiator keeps the engine cool and performing at its best. Without proper maintenance, a radiator can stop serving this important role, and that could mean serious car trouble for you in the future.

To ensure your car keeps running and has a long, fulfilling life on the road, be sure to take care of your car radiator. Below are some radiator facts and tips to help you stay on top of your car’s health.

What is a Car Radiator?

The radiator’s main role is to protect the car’s internal combustion engine. A car’s engine has many moving parts which create friction. This friction then creates a great deal of heat. The car radiator, with the help of engine coolant and water, coaxes heat away from the engine block and sends it back into the atmosphere.

Without the radiator, an engine could easily overheat and seize up on the driver. Moving parts like pistons would become too hot, evaporate any surrounding moisture, and break if not kept sufficiently cool. This could result in total engine failure and leave you with a costly transmission repair on your hands.

How Can I Keep My Radiator Working?

Dirt and debris can work its way into your car radiator and cause it to malfunction. This is an issue that can easily go unnoticed, until it turns into a serious problem. Performing routine maintenance such as radiator flushes and having your car’s fluids replaced can help ensure your vehicle’s radiator will keep working hard for you.

Hopefully this gives you a little more insight into exactly what your car’s radiator is doing for you. Remember to have the radiator flushed and all your fluids topped off during your next oil change, and you shouldn’t encounter too many overheating issues. Play it cool, and don’t neglect the radiator in your car.
