Do you own a BMW 6 Series that is leaking oil or has a high temperature? This problem could be caused by a bad oil cooler gasket; a problem that is prevalent in many BMW cars. If not addressed, this problem can cause further damage to your engine. Here is all that you need to know on how to fix it.

What Does The Oil Cooler Gasket Do?

An oil cooler gasket is a rubber-like substance that joins the oil cooler and the engine block. It assists in maintaining the right circulation of oil so that it does not spill. With time, the gasket is susceptible to wearing out as a result of heat, pressure, or even time, and this results in oil leaks and possible overheating of the engine.

Symptoms of Failure of The Oil Cooler Gasket

  • Oil Leaks: The first indication that an oil cooler gasket is failing is the presence of stains of oil on the outer surface of the car. If your BMW leaves oil stains on the driveway, or if the oil is dripping from the front of the engine, then it is high time to change the gasket. Small leaks can develop into larger ones over a period of time and this can lead to huge losses of oil which is dangerous to the engine.
  • Overheating Engine: The oil cooler is used in the engine cooling system to cool the oil so as to control the temperature of the engine. When the gasket is compromised, it hampers the efficiency of the oil cooler resulting in high temperatures. If you are experiencing frequent overheating of your BMW 6 Series then it may be as a result of a faulty oil cooler gasket.
  • Low Oil Levels: If, for instance, you find that your oil levels are low frequently and you have just filled up the car, then that is a sign of a leak. Lack of oil is very dangerous to your engine since it is needed for lubrication and cooling of the engine. You can easily notice that your BMW has a gasket problem if you check your oil levels often.

How To Repair Your BMW’s Oil Cooler Gasket

  • Inspect Gasket: First of all, it is necessary to look at the oil cooler and the area around it. Check for oil leaks around the oil cooler and signs of oil leakage or even dampness. You may also find dirt or debris stuck to the leaked oil depending on where it gushed from.
  • Drain Engine Oil: It is important to note that before you can replace the gasket, you will have to suck out the engine oil. Before doing anything you should ensure that the engine has cooled down. Drain the oil in an oil drain pan.
  • Remove Oil Cooler: In order to get to the gasket, you have to take off the oil cooler from the engine. This usually entails removing some bolts on the cooler and the detachment of the oil lines. Make sure you do not cause any harm to any neighboring parts.
  • Remove Old Gasket: When the oil cooler has been pulled out you get to the gasket that connects the cooler to the engine block. Take out the old gasket and then clean that spot so that it can fit perfectly with the new gasket.
  • Install New Gasket: Position the new gasket and ensure that there is a good fit. Replace the oil cooler and torque the bolts down properly. Make sure that all the connections are properly tightened and there is no leakage.
  • Refill Engine Oil: After that, you should put new oil into the engine. Do not use the wrong type of oil and ensure that you use the right quantity of oil in your BMW 6 Series. After the oil is added, turn the car on and let the engine run for several minutes. Look for signs of leakage to be sure that the oil cooler is working effectively.
