Product Description

This Moca oil cooler gearbox is designed for the drive train oil cooling system in select BMW models. It plays a crucial role in maintaining optimal gearbox temperatures by transferring excess heat from the gearbox oil to prevent overheating and ensure consistent operation, especially during demanding driving conditions.

Suitable for a range of BMW vehicles, this oil cooler is commonly found in models such as the E46, X3 E83, and Z4 E85, with engine codes including M43, M47, M57, N42, N46, and M54. It is important to verify your specific BMW's model, year, engine size, and engine code to ensure compatibility before purchasing.

Symptoms of a failing gearbox oil cooler can include rising gearbox temperatures, oil leaks near the cooler, shifting issues, or visible contamination in the transmission oil. You may also notice reduced gearbox performance or warning lights on the dashboard. Addressing these symptoms early can help prevent further drive train damage.

Replacing the oil cooler is recommended if you notice oil leaks, overheating, or after a gearbox rebuild. Always use new seals and check for proper hose connections when installing a replacement. If unsure, consult with a trusted mechanic or contact MiMi Auto Parts for fitment advice.

MiMi Auto Parts offers reliable delivery nationwide across South Africa, with expert support to help you find the right part for your BMW. Confirm all details before ordering to ensure a hassle-free purchase and optimal performance from your vehicle.
