What Does An Oil Cooler Do

What's Oil Cooler

The oil cooler is a miniature spring located at the front of the vehicle's engine cooling system. Its goal is to cool the oil as it passes through the coil, and it only works when the motor is running.


The oil cooler is mainly responsible for heating the oil of the car. This helps to extend the service life of oil and car engines.

Aftermarket Coolers

Normally, the oil furnace is inserted by the car owner, because most transmissions are made for installing the oil furnace.

Vehicles that Gain Most from Oil Coolers

The vehicles that benefit most oil stoves are those that perform any towing or work in hot climates. Typically, oil coolers are inserted into trucks, motorhomes, and other forms of heavy-duty vehicles.

Benefits and Pitfalls

Generally speaking, installing an oil cooler in a vehicle engine helps to extend the service life of gasoline, thereby extending the service life of the motor. However, including an oil cooler will result in the need for oil for every oil change because more oil is needed to fill the coils and traces.

What Does An Oil Cooler Do

Most of us recognize that engine optimization is one of the most important fluids found in our cars. The oil provides the required lubrication so that certain parts will not be subject to wear.

Most motors must use a heat exchanger because it eliminates the energy generated when the motor is running. If your vehicle includes a water cooling system, it will rely on a radiator.

Automotive oil coolers are selected components that help maintain the perfect temperature of the engine and its various components. It can be located in various areas of the motor to make it function better.

The oil will enter the oil cooler, although its temperature is still high. In the cooler, the oil will flow through pipes with fins.

When the oil is processed, it will leave the cooler at an already lower temperature. This cycle will continue.

Engine Oil Cooler Replacement

If you are mechanically oriented, you may choose to try to replace the engine oil cooler yourself, but the positioning can be quite tricky.

The accessories will depend on the type of car you own. So, why not stop yourself from doing this and ask for professional help?

Indicators of a Bad or Failing Oil Cooler

1. Oil leaking from the oil cooler

Among these components that are part of the oil cooling system, your oil cooler adapter is one of them. The adapter connects the oil pipe to the cooler itself, and the other adapter sends the "cooled" oil back to the oil pan.

Inside the adapter is a gasket or rubber O-ring. If the oil cooler adapter fails, the engine oil may come from the motor.

If the leak is small, you may see a puddle of engine oil on the floor under the car or truck, or you may see a stream of oil on the floor behind the car or truck.

Suppose you find any oil leaks under the engine. It is always recommended to contact a professional mechanic to determine where the traffic is coming from and to fix it immediately.

As the oil leaks, the motor loses its ability to repair itself. This can lead to increased engine temperature and premature wear of parts, as there will be greater friction in the absence of proper lubrication.

2. Engine coolant leaking from the oil cooler

Kind of like reducing oil, the collapse of the external oil cooler will cause all the engine coolant for that motor. Regardless of whether the coolant flow is large or small, the motor will overheat if it is not repaired in time.

If the flow is low, you may detect clots on the floor under the car or truck. If the flow is high, you may detect steam coming from under the hood of a car or truck.

Very similar to the ones mentioned above, once you observe the coolant flow, be sure to hire a professional mechanic. If enough coolant leaks from the radiator or oil cooler, it may cause engine overheating problems and mechanical component failure.

3. Oil at the cooling system

If the oil cooler adapter fails, you may find engine oil on the heating system. This happens because when the motor is running, the oil pressure is higher than the strain of the cooling system. The oil is forced into the heating system.

This will eventually lead to insufficient lubrication and may severely damage your motor.

4. Coolant in the oil

After the motor is not running and the heating system is pressurized, the coolant can be pressurized in the oil pan cooling system. The high sump oil volume may damage the engine because the crankshaft will be slapping oil when it emits a bad smell.

At least one of these signs requires flushing the heating system and motor to eliminate contaminated fluid. The oil cooler adapter, if it is a neglected part, needs to be replaced. It may even be necessary to flush or replace the oil cooler.
