What does the oil cooler line connect to?

While there are many parts that can be damaged through time, one worth noting is the oil cooler line. When it fails, it won’t be able to regulate oil temperature. This can cause the oil to break down and will negatively impact the way your vehicle performs. An oil cooler line connects the oil filter to the radiator.

How do oil cooler lines work?

The oil cooler is usually mounted near the radiator and will help to cool the oil with the air that is passing through the engine. The oil cooler lines of most vehicles are made from metal and have compression fittings on either end. Over time, these fittings may start to become worn.

Do you have to drain transmission fluid to change cooler lines?

Locate the transmission cooler hard lines that run into the radiator and inspect them for leaks. Disconnect the transmission cooler lines at the radiator and drain the fluid into a drain pan. Fill the transmission with the manufacturer’s recommended fluid to the proper level indicated in Owner’s Manual.

Over time, they will begin to show signs of wear due to vibrations and other road wear. If you notice that the metal part of these lines are crimped or bent, then it is time to change them. A crimped oil cooler line can prohibit or slow the flow of oil and make it hard to circulate through the cooler.

What happens if your oil cooler line leaks?

If the oil cooler lines begin to leak, they will let a good bit of the oil outside the vehicle since the lines are usually under pressure. Rather than putting a strain on the internal parts of an engine due to lack of lubrication, you will need to get the oil cooler lines replaced as soon as leaks are detected.

Do you have to drain the oil to replace oil cooler lines?

Warning: Oil is lost whenever disconnecting oil cooler lines and their components. It is recommended you have a drain pan under the oil line connection points to catch any oil that is lost during these processes. Note: Oil cooler lines can be retained by any number and type of retaining hardware.

What causes oil cooler lines to leak?
