Designed for keeping your car engine cool, the radiator is a component that requires regular maintenance. The friction of all the moving parts generates heat, and this is only exacerbated when the weather itself is warm. However, if it's malfunctioning, you could find yourself with an overheated car needing roadside assistance. Thankfully, understanding the basics can help avoid this. If you're wondering what the radiator does, here's what you need to know. 

A Guide to Car Radiators

How does the radiator cool down your engine?

Radiators prevent engines from overheating by circulating coolant throughout the system. As the coolant is pumped through, it absorbs the heat from the engine. Some radiators also have fans to help facilitate the process. 

What are some signs of radiator problems? 

You don't have to wait for a smoky engine and roadside assistance to tend to your radiator. The biggest signs of some of its problems are leaks and overheating. If you see a puddle underneath your car, there could be a leak in the tubing, which needs to be fixed. Coolant is a bright fluid with a very sweet scent. If you notice the temperature gauge on your dashboard getting too high, that's also a possible problem and should be seen by an auto repair technician. 

How often should I refill the coolant?

As you drive your car, little bits of dirt and debris can enter the engine and contaminate the coolant, thereby minimizing its efficacy over time. On average, the coolant should be flushed and replenished every two to three years—generally about every 24,000 to 36,000 miles. If you end up driving more frequently, this could be required as often as annually. 

Do I need to replace my car's radiator? 

Radiators have a life span of about eight to 10 years. Even if you haven't needed roadside assistance because of it or any other repairs, it's better to have it replaced anyway to ensure it's running efficiently. Because it's constantly used, components, like the tubes and seals, will wear down over time.
