Purpose and Role in the Oil Cooling System
The presented oil cooler is part of the Oil Coolers and Hoses group, specifically designed for the N55 gasoline engine in the BMW M2 F87. Its function is to absorb excess heat from the engine oil and dissipate it into the environment, ensuring the oil maintains a stable operating temperature range even under high loads, typical for M Performance units.
In practice, this means:
- reduced risk of oil overheating during intense driving,
- more consistent lubrication parameters at high RPMs,
- better protection for bearings, the turbocharger, and other oil-lubricated components.
Benefits of Using an Original BMW Oil Cooler
For high-performance gasoline engines like the N55 in the M2 F87, a properly functioning oil cooler is crucial for engine longevity. Using an original BMW solution ensures:
- Factory fitment with the cooling and lubrication system of the specific model, without the need for modifications.
- Appropriately selected thermal performance, tailored to the engine’s characteristics and loads.
- Compatibility with other system components, such as oil lines and mounting brackets, which simplifies installation.
This part is sourced from a dismantled vehicle, allowing for an economical repair or restoration of the oil cooling system’s functionality while maintaining the original manufacturer’s specifications.
Application in the N55 Gasoline Engine
The N55 engine is a turbocharged gasoline unit where oil operates at elevated temperatures and under significant load. Therefore, a functional external oil heat exchanger is important for both daily driving and track or spirited road driving.
Replacing the oil cooler is particularly recommended when:
- leaks or mechanical damage to the existing component have been identified,
- symptoms of oil overheating under heavy load appear,
- the vehicle has undergone modifications that increase engine power and thermal load.
Condition, Verification, and Preparation for Installation
The oil cooler is offered as a used original BMW part, sourced from a dismantled vehicle. This type of part should be thoroughly inspected for leaks, cleanliness of oil passages, and the condition of the connection spigots before reinstallation to ensure trouble-free operation in the lubrication system.
Before installation, it is recommended to:
- flush the oil system according to the service procedure,
- replace the engine oil and oil filter with new ones, conforming to BMW specifications,
- check the condition of the oil lines and mounting components.
