Oil Coolers

What to Know About Oil Coolers

Oil coolers are components found in most vehicles. Heavy duty trucks and other high  performance vehicles mostly require oil coolers to prevent their engines from overheating. Read on to find out more about oil coolers.

What are oil coolers?

These devices are used in vehicles to extract heat from engine oil. The oil coolers regulate the temperature of the oil for maximum engine efficiency. Most heavy trucks and vehicles require high-quality universal engine oil coolers to run effectively.

Oil coolers prevent overheating in heavy-duty vehicles, which makes your engine more durable in the long run. For instance, when driving for long distances, your vehicle’s engine is likely to run at maximum capacity, which would cause it to overheat. An oil cooler will get rid of the excess heat and reduce the strain on your engine.

How do they work?

Oil coolers are commonly placed in positions where they can get enough air to cool the hot oil from the engine. They can be found behind radiators or fans. The hot oil passes through the engine adapter and gets into the oil cooler, which contains tubes with fins.

While in the tubes, the oil is exposed to air, which acts as a coolant and provides a cooling effect to the oil. The fins provide a large surface area for the oil to be cooled effectively. The oil is then recirculated back to the engine. The coolant can either be liquid or air depending on the type of adapter your vehicle has.

An expert oil cooler manufacturer can help you select the best universal oil cooler kit to increase the efficiency of your truck’s engine. You can also get aftermarket coolers that you can mount on your vehicle.

Parts and functions of an oil cooler

Below are the components of a heavy-duty truck transmission cooler and their

Cooling fins

Cooling fins are components of an oil cooler that transmit excess heat from the oil to the atmosphere. They increase the surface area for efficient heat transfer.


The tubes act as a medium of heat exchange between the hot engine oil and the air outside the tubes. The tubes also direct the flow of the oil.

Adapter gasket

The adapter gasket acts as a sealant and prevents the oil from leaking. The gasket holds the oil in place to promote effective cooling and recirculation of oil.

Oil cooler hose

The oil cooler hose facilitates the movement of oil from the engine to the oil cooler.


The thermostat controls the temperature of the oil in the oil cooler transmission.

Types of oil coolers

The following are types of oil coolers based on the state of heat transfer fluids.

Oil-to-water cooler

This type of cooler uses water as the coolant. The oil runs through the tubes, and the coolant runs outside the tubes extracting heat from the oil.

Oil-to-air cooler

This type of cooler uses atmospheric air to cool the oil in the tubes of the cooler. They are positioned strategically to maximize the cooling effect of air.

Factors affecting the performance of oil coolers

Below are several factors that can affect the performance of oil coolers.


Leaking engine oil can affect the performance of your oil cooler. A puddle of engine oil underneath your vehicle could indicate an adapter failure. In this case, engine oil cooler replacement might be the solution. However, you should get your vehicle inspected first to determine the root of the problem.

Faulty thermostat

A faulty thermostat can reduce the performance of your oil cooler. When the thermostat is faulty, it might fail to regulate the temperature of the oil resulting in undercooling or overheating of the engine.
