1. Jack up your Vehicle

The first thing that you have to do is to park the car on an even surface and jack it up. You need to access the hood when removing and replacing the oil cooler line. Make sure to find a place where the surface is stable, which is important for your safety. It should also have the lighting that you need to be able to work properly.

If you want to be safer, it will be best to also use wheel chocks. This will lock the wheel and prevent it from rolling while you are working underneath.

2. Remove the Oil Cooler Line

Once the vehicle is already in a set position, you should locate the oil cooler lines in the hood. After it is located, start having it removed. Take it out from the point where it is connected to the engine. Use a ratchet or a wrench to remove the bolts that serve as the connector of the oil cooler line. Loosen and unplug.

After removing it from under the car, remove the one from the top. Loosen the bolts that connect the line. Wiggle and pull it out slowly.

3. Drain Excess Oil

After you have removed the oil cooler line, the next thing that you have to do is to remove any excess oil. It will drip from underneath, so do not forget to place an oil pan to catch the drippings. You might end up with a mess if you do not have a pan to catch the excess oil.

4. Compare the Oil Cooler Line

Before placing the new oil cooler line, have it compared with the old one. Make sure that they have the same shape and length. It is important to have the same design so that you can mount it in its original position. It must also have the required bends to have the clearance that is necessary to complete its assembly.

5. Check the Seals

Seals are important because they will prevent leaking and make sure that the lines will be tight and secured. The seals can exist in different forms, such as gaskets and O-rings, among others. If they are not included in the replacement oil cooler lines, you will have to purchase them separately.

6. Install the New Oil Cooler Line

At this point, you should be ready for the installation of the replacement oil cooler line. First, install the new line on the side of the oil cooler. Once you are done, install it on the engine side. See to it that the nuts or bolts will be tight. Otherwise, you might end up suffering from leaks. Reinstall all of the mounting brackets.
