Engine oil in an automotive lubricates helping to regulate the temperature of moving metallic portions of an engine or transmissions. The surfaces of such components produce friction, which generates heat; without having a cooler, oil can prematurely break-down, eventually causing engine wear and failure.

There’s two forms of oil coolers, the fin and tube system, and the tube and shell system. The tube and fin method is normally positioned in front of the car radiator, and engine oil passing through copper tubes is cooled down by air via the system’s fins. The shell and tube cooling system circulates liquid coolant or water around a set of tubes to cool down the heated oil.

Standard vehicles usually have no requirement for engine oil coolers as their radiators are adequate to supply the cooling demands of engines. Oil coolers are generally installed on specialized automobiles, like racing cars, high-performance cars, towing trucks, and extra-large vehicles that haul serious loads.

The Pros & Cons of Engine Oil Coolers

Engine oil coolers are the aftermarket addition for a vehicle. They take advantage of the science of the radiator and put it toward the engine oil, to maintain it cooler over a standard vehicle’s oil source.


Engine oil coolers move around the engine oil by having a maze of tubes that consequently cools it. Temperatures can shift 30 degrees less than standard oil temperatures via cooler flowing air within the engine compartment.


In case a vehicle tends to off-road or carry consistent hefty loads, an engine oil cooler can assist extend the engine life. By keeping this oil cool, it prevents heating up during stressful lugging jobs.


The downsides to engine oil coolers consist of difficulty of placement. The cooler can’t be connected to the back of the radiator but needs proper airflow to perform. Attaching them back aside from the radiator is an option if space is accessible. Also, in case the vehicle in question doesn’t haul hefty items or off-road in diverse places, an engine oil cooler might be an excessive addition since the standard engine can calme the oil effectively in normal driving circumstances.
