Best Oil Cooler for Harley Davidson: Make the Engine Work Better

SaveSavedRemoved 0

Even the premium motorcycle engines may wear out after some time. It usually happens because of the wrong supervision. The engine requires checking on a routine basis. However, you can prevent a lot of motor damage using an oil cooler. It decreases the device heating – the engine lives longer if it works at the optimal temperature.

The best oil cooler for Harley Davidson I have encountered is Jagg 6 row oil cooler. It is supplied with innovative cooling and hyper flow technologies for the best engine performance. The design allows us to cool down all the motor components. In my Harley Davidson oil cooler review, you will find other options too.

Top 5 Best Harley Oil Coolers

It’s not that complicated to find a suitable oil cooler for Harley Davidson. However, I think these reviews will help you make it faster and easier.

1. Jagg 6-Row Oil Cooler – Best Oil Cooler for Harley Davidson

Jagg Oil Coolers Vertical 6

Jagg company has been producing the oil coolers for Harley Davidson motorcycles for a long time and still remains the most prevalent manufacturer. The reason for this is their passion for implementing technologies. They also offer the devices for Buell, Honda, Yamaha, and universal oil cooler – as you can see, the Jagg brand has a high level of trust.

The kit has everything you need to install the device – no additional instruments are required. You will get highly-durable Uralite clamps. They allow mounting the oil cooler in the direct airflow that increases its productivity and lifespan. Also, the high-flow oil filter adapter is included. It makes the oil flow through the filter first that decreases the temperature directly.

This model is the top pick on the market now because it combines simplicity and effectiveness. It is lightweight – the cooler weighs only 1.6 ounces. The dimensions are 12 x 6 x 9 inches, which makes the device compact and quiet. Also, thanks to the small size, the oil cooler has high-efficiency but consumes less energy.

You need to measure what option fits you most before buying – all the dimensions are noted. Besides the oil cooler, the kit includes some equipment you need for installation.

You will get two oil lines, mounting nut and oil filter adapters, fuel hose. However, you should buy the hardware and brackets separately. The cooler is made of aluminum. This material is one of the most durable ones because it hardly gets damaged and becomes rusty slowly. Also, the construction is strong but weighs a little.

Evil Energy oil cooler doesn’t only cool the engine oil – it decreases the temperature of transmission and rear-differentials. As a result, the engine lifespan increases a lot. The machine will serve you for longer because the oil doesn’t heat too much, and all the motor components work in the right way.

The 10 row oil cooler basically likes a radiator to cool down your engine oil. When your engine spins under high load at high rpm, it creates friction and that heat from that friction is transmitted into the oil and than the oil over heats, when the oil breaks down, it doesn't lubricate well and reduces your engine life over time.

  • The 10 row oil cooler kit basically just cools the oil down, the greater the surface area, the more air we have and the more tubes we have exposed to the air and the more heat we can dissipate or get rid of.

However, it keeps the same efficiency as the standard models with a lower performance level. The cooler has dual waterproof fans. They make the cooling process faster and decrease the temperature even more.

The Most Essential Facts About the Oil Coolers

Jagg Fan-Assisted Oil Cooler

Many people forget about oil coolers and believe that they don’t need them. But they’re significant for the right motorcycle work. Here you will find the answers to the most common questions about the oil coolers.

Do I need an oil cooler on my Harley?

Firstly, an oil cooler increases the engine lifespan a lot. It doesn’t allow the motor to overheat, and, as a result, the machine gets damaged less possibly. Also, your Harley will work much quieter. The oil cooler doesn’t require a lot of fuel just because it decreases engine consumption.

Do oil coolers work on Harley Davidson?

The oil coolers for the Harley-Davidson motorcycles work in most cases – but diverse models decrease various temperature ranges. Some of them may cause a 5-10 degrees difference. More innovative systems provide 15-20 degrees cooling. However, it’s not always good for engines to work at too low temperatures, that’s why I recommend you to choose the coolers with medium performance.

How can I make my Harley run cooler?

Mostly all the Harley Davidson motorcycles are adapted to the oil coolers. So, the device will run perfectly right after the installation. It’s not difficult to set the cooling system. Many manufacturers provide a mechanism that doesn’t require additional tools – you just need to push it over the oil filter. But most oil coolers need handy tools. Don’t worry – even if the kit misses something, you can find it at home for sure.

What oil does Harley Davidson recommend?

You may choose from the two types of oil – semi-synthetic and full-synthetic. The fuel should have a high viscosity index number. It provides low-temperature engine performance. But you also should choose the oil that suits your model the most – it can be even the mineral one. By the way, you can use diverse oils for summer and winter. Using Biodiesel fuel in your engine is also possible. With the oil cooler, you will be able to try a wider fuel range with no doubts.

Let Your Harley Davidson Live Longer

I think most people want to enjoy a perfect motorcycle performance for years, not for several months. A good oil cooler may easily provide this. With the Jagg 6-row oil cooler, your Harley Davidson engine will work more efficiently and reliably. This model is the top choice on the market now – and its characteristics measure up this rank.
