How Does Engine Oil Cooler Work? Get The Facts!

There is no doubt that when your car engine is operating, especially during the summer months, and when you are driving long distances, you are more at risk of having an overheating issue.

To prevent this from ever happening to you, your engine needs to be cooled continuously. This is the very reason why an engine oil cooler is very important since it helps to regulate the temperature and maintain the peak performance of the engine.

In this article, we are going to explain all you need to know about how an engine oil cooler works. The car engine oil cooler has been overlooked at times, especially for people who are not as mechanically minded.

What is an Engine Oil Cooler?

Let’s start by saying that an engine oil cooler is considered to be a component of your car’s radiator system. What it does is move around a maze of pipes in an engine which enables it to provide a cooling effect. It can lessen the temperature by as much as 30 degrees, which helps to prevent the engine from being too hot.

Apart from that, the engine oil cooler also helps when it comes to maintaining the right level of viscosity. If it’s a case where there is too much heat, the viscosity will be a lot lesser. What this means is that the oil will have a harder time in terms of clinging to the components.

By now we all know that engine oil is one of the most important fluids that can be found in our cars. The moving parts of the engine will create friction and external condition can result in the components being heated up. Oil is known to provide the lubrication necessary to ensure that the parts don’t suffer any form of wear and tear.

With that being said, a heat exchanger is very important for all engines, as it gets rid of the energy that is created by the engine as it is running. If it’s a case where your vehicle has a water cooling system, it will then rely on the function of the radiator.

It is safe to say that a car oil cooler is a component that helps keep the optimal temperature range of the engine and its parts. To make things easier, it can be positioned in different places in the engine which makes things more suitable.

At this point, the oil will enter the oil cooler while its temperature is still high. Inside the cooler, it oil will then go around tubes that are fitted with fins that released heat. Once the oil is properly processed, it will leave the cooler at a colder temperature. This process will then continue over and over again.

Engine Oil Cooler Replacement

If you are a handy person, you may want to take the time out to replace your engine cooler yourself, however, you may have a hard time when it comes to positioning it. It’s best to keep in mind that the attachment will be determined by the type of vehicle you have.

There you go, we have discussed everything you need to know about how engine oil works. As you can see, it enables the engine to maintain its peak performance and does a wonderful job of prolonging its functional life through the cooling it provides. The biggest downside is that the positioning can be a bit difficult, but if you are not a handyman, you can get a professional to get the job done.
