How a Car Radiator Works

A car radiator is one of the primary components of the vehicles cooling system. You’ve heard of coolant before; right? Also known as radiator fluid or anti-freeze, coolant is a vital automotive fluid that is designed to absorb the heat that is generated by the vehicle’s running motor. After coolant absorbs enough engine heat, it travels through the car radiator where it is cooled and then circulated back into the engine to start the process over again.

How to Spot the Signs of a Failing Radiator

There are many signs and symptoms that can suggest a problem with a car’s radiator, but for top the list the majority of the time. These include coolant leaks, engine overheating, radiator sludge, and local levels. If you have noticed any of these 4 signs, you can safely assume the radiator is failing or going bad.


If you notice that your coolant levels are inconsistent, or you are refilling your coolant more often than normal, it could be a sign that your radiator is having problems. Typically, your dashboard will have a low coolant line that will eliminate when equivalent levels are too low. More often, this is a sign of a coolant leak.


If you’ve noticed coolant accumulating on the floor below your vehicle, you can safely assume you’ve got a radiator leak coolant on your hands. This is a common radiator breakdown problem that requires immediate automotive repair attention. Typically, this is a result of a crack in the radiator.


The presence of radiator sludge is another tell-tale sign of a bad radiator. Radiator sludge can be detected when checking your coolant levels. Radiator fluid is typically red or green in color, but if there is an excessive level of radiator sludge present, your coolant will take on a rusty or brown color and appear sicker than normal.


If your car engine is constantly overheating, the radiator might be the first place you want to look. After all, your radiator is a vital component within the automotive cooling system; so, if your engine is getting too hot, it is very likely that your radiator is not doing its job well enough.
