5 Best Oil Cooler for Harley Davidson of 2022

Oil cooler control how well your engine runs and how healthy it remains. While driving, it makes sure your engine remains perfect. Without it, you could be looking at major engine damage or even catastrophic failure! Oil coolers are very basic systems and it might be easy to ignore the benefits of having an oil cooler on your bike. However, here is a comprehensive guide on the benefits and recommendations of the Best Oil Cooler for Harley Davidson. So, let’s begin.

Types of Oil Coolers

There are three types of oil cooling systems that work for Harley Davidson. The coolers have varying benefits. Below is an overview.

Air-Cooling: This cooler is common among smaller engines. The system involves passing air through the casing of the engine. As a result, the air dissipates the extra heat during the motion. This system does not require an oil cooler but rather a thermal transmission.

Air/ Oil-cooling: It is the hybrid of the two systems. It combines an air cooling and an oil cooler—the oil-cooler supplements the air cooler by removing the heat from the motorcycle’s engine. Despite the modification, it is not what you should go for if you have a high-performance engine.

Liquid-Cooling: This system has a coolant that is liquid in nature. The liquid in an external radiator circulates the engine and, in the process, dissipates heat. The liquid cooling system is the most effective for high-performance engines but is costly.

Benefits of Oil Cooler for Harley Davidson

Overheating: The primary reason why motorcycles have a cooling system is to prevent engine oil from overheating. Having an oil cooler keeps the engine oil in usable viscosity. The result of this is a smooth and memorable journey.

Protection: Having an oil cooler helps protect your engine. It keeps the engine oil viscous to ensure the engine plates do not grind on each other. In simple terms, this protects your engine in the long term from potential damage.

Effectiveness: An oil cooler guarantees good service and an undisrupted journey. Overheating of the engine can delay your journey. Having it on your bike lowers the temperatures and ensures the engine is working properly.

Buying Consideration for the Best Oil Cooler for Harley Davidson

Size: An oil cooler is supposed to pass fluid and, in the process, dissipate the heat. Therefore, the higher the fluid circulation in the cooler, the more the heat-exchange levels. The inlet and outlet size, therefore, directly affect the fluid flow. Ensure the oil cooler you buy has enough size of the inlet and outlet for more heat loss.

Budget: The amount of money you’re willing to spend on an oil cooler will affect the quality you get. On average, the cost of an oil cooler ranges between $100 and $500. The higher the cost, the more the quality. Depending on what your budget is, ensure that you balance the cost and the quality.

Installation: Ensure that you buy an oil cooler that wouldn’t give you sleepless nights trying to install. Buying an oil cooler that needs a mechanic only helps hike your budget. Additionally, you can ensure that the cooler comes with an installation manual.

Durability: This factor should have been number one in the buyers’ consideration. No one loves to keep buying the same item over and over again. Ensure that you check what other customers are saying about that particular oil cooler. Buying a durable piece will protect you from leakages and breakages.

Fitment: It is vital to check if the particular oil cooler fits in your motorcycle. Fitment of oil coolers in motorcycles is not universal. Therefore, ensure to compare its fitment with your bike’s model. It will save you from possible troubles.

Harley Davidson Oil Cooler Installation Instructions

You can have a mechanic install your oil cooler. However, you can as well do it yourself as the steps involved are easy to understand. Below, we have captured the main stepping stones.

Step 1- Drain all the existing oil. Draining the pre-existing oil keeps your motorcycle’s interior safe from possible spills and damage.

Step 2- Remove pre-existing wires. Disconnecting the wires that may be in the position creates more room for installation.

Step 3Install the oil cooler. In case you’re swapping, disconnect the already existing one. In case none pre-existed, use your owner’s manual to start the installation process. Depending on your Harley model, the installation process may be a little different.

Step 4- Install the hoses. Connect the oil cooler with the oil line so that the oil first goes to the cooler. Ensure that you fasten the connection ends to avoid leakages.

Step 5- Refill the oil. Remember that in the first step, we emptied the existing oil? It’s time to refill back the oil levels. The installation manual for your bike might probably guide you on the level you’re supposed to refill.

Step 6- Take a road test. Start and run your bike for several minutes. Take key attention to whether the oil is flowing properly, warming up, or any leakages. Generally, check for any abnormalities.
