A BMW oil cooler assembly usually consists of several key components, and its specific composition may vary slightly among vehicle models and engine types. The following are general components of a BMW oil cooler assembly: 

1. Cooler body

As the core part of the cooler, it provides heat exchange function. It is often made of aluminum, and features excellent heat dissipation.

2. Oil filter

Some BMW models have an integrated oil cooler, which filters impurities in the oil and ensures that the oil entering the cooler is clean.

3. Oil port

There are typically several oil ports on the cooler. They are connected to the oil pipes to ensure smooth oil flow. The direction of oil flow is often marked on each oil port.

4. Enclosure

It encapsulates and protects the internal structure of the cooler, and withstands high oil pressure and extreme temperatures. It is typically made of metals.

5. Sealing ring and gasket

They are used to prevent oil leakage. These parts are usually made of oil-resistant materials to ensure good sealing effect of all interfaces.

6. Connection pipe

The oil inlet and outlet pipes connect the cooler to the oil pump and the engine, and maintain constant oil flow.

7. Mounting bracket

The bracket or the fixing device secures the cooler to the engine or the vehicle body firmly.

8. Temperature control valve

Some vehicle models may be equipped with temperature control valves to better regulate the flow of oil and coolant and to optimize cooling performance.

These components work in conjunction effectively to maintain a reasonable oil temperature for the BMW oil cooler under high temperature conditions, thereby protecting the engine and ensuring high performance.
