Nissens 90698 - Oil Coiler

An oil coiler, also known as an oil cooler, is a device that is used to cool the engine oil in a car. It is typically located in front of the radiator, and it works by passing the oil through a series of tubes that are filled with air. The air helps to cool the oil, which then flows back into the engine.

Oil coilers are important because they help to prevent the engine from overheating. When the engine is hot, the oil can become thin and lose its ability to lubricate the engine. This can cause the engine to seize, which can be a very serious problem. Oil coilers help to keep the oil cool, which prevents it from becoming thin and losing its ability to lubricate the engine.

Oil coilers are typically made of metal, and they are usually finned to help with heat dissipation. The fins help to increase the surface area of the oil coiler, which allows it to dissipate heat more effectively.

Oil coilers are usually maintenance-free, but they should be inspected regularly for signs of wear or damage. If the oil coiler is damaged, it should be replaced as soon as possible.
