Review GM Engineering Air Oil Separator 2500/3500 6.6l Diesel fits 2500 3500

The 81-0812 Air Oil Separator is a crucial component in the cooling system of GM 2500/3500 6.6L diesel engines. This separator is designed to reduce the amount of air and contaminants that mix with engine oil, ensuring a cleaner and more efficient engine operation.

The separator housing is made of durable cast aluminum, which provides excellent heat dissipation and resistance to corrosion. The inlet and outlet connections are made of sturdy steel, ensuring a secure and leak-free fit. The unit comes with a removable bowl made of stainless steel, which makes it easy to drain and clean.

The 81-0812 Air Oil Separator utilizes a centrifugal force to separate the oil from the air and contaminants. As the engine oil enters the separator, it comes into contact with the spinning bowl. The heavier oil droplets settle at the bottom of the bowl, while the lighter air and contaminants are forced out through the breather tube.

The separator is equipped with a breather tube that vents the separated air to the intake manifold or to the atmosphere. This not only helps to maintain proper crankcase pressure but also ensures that clean, dry air is introduced into the engine.

The 81-0812 Air Oil Separator is a direct replacement for the original equipment on GM 2500/3500 6.6L diesel engines. It meets or exceeds all OEM specifications and is backed by a warranty for added peace of mind. Installation is straightforward, and the unit comes with all necessary hardware for a hassle-free installation process.

In summary, the 81-0812 Air Oil Separator is an essential upgrade for any GM 2500/3500 6.6L diesel engine, providing improved engine performance, longer oil life, and enhanced engine protection. With its robust construction, efficient design, and easy installation process, this separator is an excellent investment for any diesel engine enthusiast or fleet operator.
