What Does A Car Radiator Do?

What does a car radiator do?

The radiator on your car ensures that the engine in your car stays cool. The radiator does this by way of cooling the coolant coming from the engine. The coolant is cooled down by the air from outside which the radiator fan pushes through the radiator. That way the radiator is able to dissipate the heat from the coolant, and pass cool air back to the engine.

Radiators are put together from a number of parts, with main part being the core. The radiator core has a small tank on each side through which the coolant passes. The core itself consists of a large number of narrow coolant channels where air can pass along to cool the coolant down.

In some cases the radiator may struggle to keep the engine cool. It may be in those cases that there is something wrong with the radiator. It may be that some of radiators channels are blocked, for example, due to debris or rust. It’s important to get problems like that resolved as it can lead to the coolant becoming too hot.

Remember, especially in summer when it is hot the radiator will often struggle to keep the coolant cool. So any little problems with the radiator can quickly turn into an engine that overheats. Ultimately this can cause great damage to the engine.
