Symptoms of Bad or Failing Oil Cooler Lines

oil cooler line

Most car owners fail to realize just how important it is to keep their engine oil cooled. It is very hard for the internal parts of your engine to use oil if it is at a high temperature due to the viscosity it has, The hotter the oil gets the thinner it gets and the less it protects the engine. There are a variety of systems on a car that will help to regulate the temperature of the oil. Among the most important parts of this system is the engine oil cooler. In order to pump the oil into the cooler, the oil cooler lines have to be working properly. These lines, made of rubber and metal, send the oil from the crankcase to the cooler.

These lines will take a lot of abuse over the years and will eventually need to be replaced. Noticing the warning signs that your car will give when this part is damaged can save you a lot of trouble and potentially save from extensive repair bills for the engine. The following are some of the things that you may notice when it is time to get your oil cooler lines replaced.

1. Low oil levels

Having lower than normal oil in your car can be very hazardous. 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. What causes hoses to leakRunning the vehicle without the right amount of oil will usually lead to a variety of different problems and can include engine failure if left unattended. 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. Replacing these signs as soon as the leak is detected will prevent major headaches and expensive repairs.

2. Crimps or bends in the hose

Oil cooler lines are made up of hard metal lines and flexible sections of rubber hose, the metal ends screw into the engine block. 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.

3. Oil leaks and puddles under the car

A puddle of oil under the vehicle is an obvious sign that an issue is present and should not be ignored. The oil should be checked as soon as possible. If you are starting to notice that there are oil puddles under the car, then you may need to replace the oil cooler lines. Damage to the oil cooler lines is quite common and can take a toll on the functionality of a car if not fixed in a hurry. The oil cooler lines can be damaged for many different reasons such as age, road debris, old oil or simply becoming clogged over time. If you are ever unsure what fluid is leaking under the car or would like a second opinion, get an oil and fluid leak inspection.
