Diagnosing Common Concerns with Your Mazda Millenia Oil Cooler Seal
There is a smaller radiator coming from the engine's main radiator that cools the oil and maintains its temperature at an optimal value. This is called an oil cooler, and it is one of the most essential parts of a car's cooling system. Without it, oil can get too hot, break down, and lose its lubricating properties prematurely-along with its cooling abilities, of course. Your Mazda Millenia oil cooler seal helps maintain oil temperature between 180 and 200 degrees Fahrenheit. It does this by keeping oil on one side of the cooling system and dirt on the other. When it fails, there is a noticeable drop in the car's performance. Listed here are some ways to diagnose and troubleshoot problems with your oil cooler seal:
There is a white mixture in the coolant tank.
When you see a white milkshake-looking mixture forming in the coolant tank, it means you have a leak somewhere in your cooling system. Although this could also be the result of a failing head gasket, it's usually a broken oil cooler seal that's causing the problem. The presence of the mixture could mean oil has made its way into the coolant tank. This does not pose great and immediate danger but can be very messy and hard to clean. Over time, however, the coolant will make its way into the oil system and may cause further damage to the other car parts. The engine cannot run with coolant present in the oil system.
Unfortunately, there is no way to fix a busted oil cooler seal-it needs to be replaced immediately. To inspect for damage, locate the seal. It is placed between the engine block's mounting flange and the oil cooler itself. Check if it is cracked after removing the coolant hose. Note that the cooling system needs to be flushed after replacing the seal.
Oil spills out the driveway whenever you start your car.
You're in a big hurry and you feel you won't make it to your meeting in time. You start your car and drive as fast as you can. When you get home you notice there are small oil spills on your driveway. This could be attributed to a broken seal, which might be causing a leak. In this case, the oil does not go directly into the coolant tank, but drips directly to the ground.
