Tips to Properly Maintain Your Engine Oil Cooler

The engine oil cooler is an important component of your vehicle’s engine, but that doesn’t mean you should ignore it. If you fail to keep it clean, the performance of your car can drop sharply over time, and eventually your engine could even overheat. Here are some tips to help you properly maintain your engine oil cooler so you can continue driving without problems.

How an oil cooler works

An engine oil cooler is an air-to-oil heat exchanger. It’s used in a car or truck engine as a way of keeping the engine’s oil from overheating. A heat exchanger is a device that transfers heat from one fluid to another by flowing them through opposite sides of the same metal plates, with the higher temperature fluid passing over the cooler (i.e., lower temperature) fluid. The process works in this case because when oil reaches its boiling point, it changes into gas, which can then be released from the system and cooled back down. To help prevent problems like corrosion, it’s important to keep your oil cooler clean and properly maintained. Follow these tips for more information on how you can do just that: 

1) Clean your engine’s oil cooler at least once per year with a soap-based cleaner. 

2) Check for leaks regularly so you don’t end up damaging any components on your vehicle and have to pay for expensive repairs or replacements later on. If you do find leaks, stop driving immediately and have them repaired by an auto technician as soon as possible before the damage worsens. 

3) Look for signs of potential problems like dirt buildup near the hoses where they connect to the radiator or beneath the hoses themselves if they’re visibly leaking from underneath.

How to avoid an oil cooler failure

In order to avoid an oil cooler failure, you should follow these guidelines: 

– Change your engine oil and filter every 10,000 miles or at least every year.

 – Keep your engine tuned up as well as keep it properly maintained. 

– Keep the radiator system clean and replace the coolant when needed. 

– Have a mechanic check out your car regularly for any potential problems with the cooling system.

The benefits of maintaining it

Maintaining your engine oil cooler is important for a myriad of reasons. It’s one of the most neglected and under-appreciated components on your car, but it can be the difference between life and death if it breaks down while you’re driving. Here are some tips on how to maintain your engine oil cooler so that you don’t end up with a huge headache when you need it most: 

– Clean out any debris that has accumulated in the radiator fins. 

– Ensure the filler neck isn’t leaking by filling it with water and watching for bubbles. 

– Check the drain plug, which should be fastened securely.


The engine oil cooler is a vital component of your car’s cooling system and can save you from more expensive repairs. However, many people are neglectful of their engine oil cooler and do not maintain it as often as they should.
