Oil Coolers: Everything you need to know about Engine oil coolers


Oil Coolers: Everything you need to know about Engine oil coolers


An oil cooler is a smaller radiator separating from an engine’s main radiator. It maintains oil supplies at a consistent, optimal temperature. Broadly put, lower oil temperatures prolong the life of an engine or transmission.


What is the purpose of the engine oil cooler?

The purpose of the engine oil cooler is to allow the engine’s cooling system to remove excess heat from the oil. … The heat absorbed by the engine’s cooling system is then transferred to the air as it passes through the vehicle’s radiator, which is located in front of the engine behind the grille of the vehicle.

Is an oil cooler necessary?

Unless you know how hot your oil is, you have no idea if you need a cooler or not. Oil that is too cold doesn’t work properly. Coolant temps affect oil temps as well. You don’t need to worry about overcooling if you have an oil thermostat


Signs of oil cooler failure?

Signs of Engine Oil Cooler Failure

1.            Decreased Performance. If the oil cooler is failing in your vehicle, the first thing you’ll notice is decreased performance from the engine. …

2.            Black Smoke. Smoke is another prominent sign as damage to the cooler may actually cause oil to leak out of the engine and into the combustion chambers. …

3.            Vibrations. …

4.            Distended Radiator.


Where is the oil cooler located?

Engine oil coolers are small radiators placed in front of the coolant system on an automobile that lower the temperature of the oil as it passes through the coils. It is only operational when the motor is running. Lowering the temperature of engine oil has many advantages, especially in air-cooled motors.


How does the Oil Cooler help the engine?

It moves around a maze of pipes in an engine to provide a cooling effect. It can lessen the temperature by as much as 30 degrees, which is why it can prevent the engine from being too hot. Engine oil cooler also helps in maintaining the right level of viscosity. If there is too much heat, the viscosity will be less.


Is an oil cooler a radiator?

Oil cooling is the use of engine oil as a coolant, typically to remove surplus heat from an internal combustion engine. The hot engine transfers heat to the oil which then usually passes through a heat-exchanger, typically a type of radiator known as an oil cooler.



How much does the oil cooler really help?


Changing the oil often keeps the lubricating ability boosted, and an oil cooler system can maintain the quality of oil for longer periods of time by lowering the working temperature of the oil by as much as 30 percent


Do all cars have Engine oil coolers?


Actually, many cars do not have an engine oil cooler. Typically most engines are designed so that the engine oil is cooled by air flow. … Most vehicles will not have an engine oil cooler, but they may have a cooler for the transmission


What is better oil cooled or air cooled?


In essence, oil cooling is just air cooling with an additional cooling mechanism. Pros – This is more efficient than simple air cooling. It is cheaper as well as technologically simple and easier to maintain. Cons – Not as efficient as Liquid cooling and cannot be installed on high performance engines.
