OIL COOLER AUTOMATIC TRANSMISSION FOR BMW 5/E60/7/E66/E67/E61 M54B25 2.5L 6cyl FEBI BILSTEIN 100126

In modern cars, cooling systems are used that allow not only to cool the moving parts of the box, but also to lubricate them. The automatic transmission cooling system consists of:

1. cooling radiator with heat exchanger;
2. cooling system pump;
3. cooling system pipes;
4. liquid temperature sensor;
5. transmission fluid.

The functionality of the oil cooler

The design of the automatic transmission oil cooler is practically no different from the radiator for the internal combustion engine.

The principle of operation is also similar, that is, the automatic transmission oil is pumped through the radiator for cooling.

FEBI BILSTEIN brand Oil Cooler, automatic transmissionAs a rule, a box-cooling radiator consists of the following elements:

1. top and bottom tanks (made of brass to ensure good thermal conductivity);
2. core (thin transverse plates and flat vertical tubes soldered to these plates);
3. fastening parts.

Another thing to note is the heat exchanger, which acts as part of the main cooling radiator. Under the condition of operation in a climate of the middle zone, a heat exchanger is used to maintain a constant temperature in the hydraulic medium of the automatic transmission (an additional circuit in the radiator of the cooling system). Most often, the heat exchanger is built into the box radiator.
