The Procedure of How to Install Engine Oil Coolers

Check out the installation process of an Engine Oil Coolers with Car From Japan right below! Oil cooler is a small device placed in the radiator design of the vehicle.

As the name suggests, its function is to cool down the temperature of oil entering the engine. By this, it assists in maintaining the optimal temperature and viscosity of the fuel before being used for lubrication of engine and transmission.

Moreover, its significance in the motorable vehicle has made it essential to ensure its proper installation in the vehicle. And, to check its setup, it is critical to understand the engine oil coolers and how to install it.

Systematic Installation of Engine Oil Coolers

Before commencing with the installation of the engine oil cooler, it is vital to understand that if this small radiator is not installed carefully then, it may also lead to the engine failure.

Tip: The position of the engine oil cooler should not be near or next to exhaust components, thrown gravel, ice, water, or road grime.

Required Parts List

In order to ensure the proper and smooth installation process, make sure that you are equipped with the following mentioned tools.

• Oil Cooler with Barb Fittings
• O-ring (One each of two different sizes)
• Sandwich Adapter
• Instruction Sheet
• Oil Hose, Neoprene
• Adapter Plate
• 2 Hose Adapter Fitting 
• 5 Mounting Nuts
• Pipe Thread

Apart from this, the hardware installation kit (each with the quantity of four) comprises:

• Nylon Washer
• Push Nut
• Mounting Bolt
• Rubber Spacer

Note: The dimensions of each component vary as per the size of the vehicle in which the engine oil cooler is installed.

How to Install Engine Oil Coolers

To start with, check the sharp edges in the work area and make sure that you do not expose the oil hose to the hot surface.

Also, keep the length of hoses longer than the taken measurements and always use pipe thread in all the fittings. However, it is suggested not to over-tight the fittings.

1. Decide the Mounting Location

For the best location of the motor oil cooler in the system, it is advised to install it, where it will receive the most of the cool air from the vehicle fan and motor.

2. Inspection of Filter

First, insert the sandwich adapter’s depth into the oil filter in order to confirm its clearance. In case, there is not enough clearance in the filter then, its remote mounting is done or a short filter is used. Here, the short filter’s thread must adjust the adapter.

3. Mount the Engine Oil Cooler

Step1: Install the pipe thread fitting into the sandwich adapter and the cooler. Next, just place the engine oil cooler (do not fit yet) where you want to install it.

Step2: Coat the oil of the engine onto the O-ring seal of the sandwich adapter.

Step3: Then, with the right-colored ring, insert the adapter and tighten it in the cylinder block over the adapter.

Step4: Next, for the routed hose, make sure to position all the fittings on the sandwich adapter and toughen the nuts on it.

Step5: Followed by this, cut the hoses more than the rough length and insert it in the cooler with 90o turns or with greater radius. By this, it would allow for the easy flow of the oil through the cooler.

Step 6: Use two wrenches. With one support the cooler and with another, affix the bolts on it. In addition to it, use an electric drill for the insertion of bolts.

Step 7: Place and attach all the fittings on the engine oil coolers.

4. Test the Installation of Engine Oil Coolers

To test the oil coolers, start the engine and look for the oil pressure and oil cooler radiator in the system. 

If both ends of the cooler are warm after a certain time, this confirms the proper installation of it. Or else troubleshoot the problem and re-concern the instruction guide.

Hence, after knowing how to install engine oil coolers, if this system is checked regularly then, it is also easy to follow its maintenance over a longer period.

FAQs on Engine Oil Coolers

1. Are there different types of engine oil coolers available?

There are various types, including air-to-oil coolers, liquid-to-liquid coolers, and even electric oil coolers. The choice depends on your vehicle’s needs and intended use.

2. Can an engine oil cooler improve fuel efficiency?

In some cases, yes. By maintaining optimal engine temperatures, an oil cooler can improve engine efficiency, potentially leading to better fuel economy, especially in high-stress situations like towing.

3. Are there any maintenance requirements for engine oil coolers?

Routine maintenance includes checking for leaks, ensuring hoses are secure, and cleaning the cooler’s fins to remove debris that may hinder airflow. Follow the manufacturer’s guidelines for specific maintenance recommendations.

4. Can I use an aftermarket oil cooler on any vehicle?

While many vehicles can benefit from an aftermarket oil cooler, compatibility depends on factors like the vehicle’s make, model, and engine type. Consult with a professional or the cooler’s manufacturer to ensure compatibility.

5. Is an engine oil cooler necessary for daily driving?

For typical daily driving in moderate conditions, an engine oil cooler may not be necessary. It’s more beneficial for vehicles under heavy load, in extreme heat, or for performance applications where oil temperature control is crucial.

6. Can an engine oil cooler increase the lifespan of my engine?

An engine oil cooler can help extend the lifespan of your engine by maintaining lower oil temperatures. 

Cooler oil provides better lubrication, reduces wear and tear on engine components, and minimizes the risk of overheating, all of which contribute to a longer-lasting engine.

7. Are there any potential drawbacks or considerations when installing an engine oil cooler?

While engine oil coolers offer numerous benefits, there are some considerations to keep in mind. They can add extra weight, cost, and complexity to your vehicle. 

Improper installation or choosing an oversized cooler can lead to overcooling, which might affect engine performance. 

Additionally, oil cooler placement can impact airflow to other essential components like the radiator, potentially affecting the engine’s cooling system. 

Therefore, it’s essential to carefully plan the installation and choose the right engine oil coolers for your specific needs and vehicle.
