Product Description

This Cooltec oil cooler gearbox is designed for the drive train oil cooling system in select BMW models. It plays a vital role in regulating gearbox oil temperature, helping to maintain optimal performance and protect internal transmission components from excessive heat. The robust aluminium construction and efficient stacked plate design ensure effective heat dissipation during demanding driving conditions.

This oil cooler is compatible with BMW vehicles, specifically models such as the X5 E53 series equipped with engines like the 3.0d M57, 3.0i M54, 4.4, and 4.6is M62, produced between 1999 and 2006. Always confirm your vehicle's model, year, engine size, and engine code before placing your order to ensure correct fitment.

Common symptoms of a failing gearbox oil cooler include overheating transmission, erratic shifting, transmission warning lights, visible oil leaks near the cooler, burnt-smelling transmission fluid, slipping gears, or increased gearbox noise. If you notice any of these issues, inspection and replacement may be necessary to prevent further damage.

Replacing the oil cooler is important if you detect leaks, reduced cooling efficiency, or a drop in transmission performance. Early intervention can help avoid costly repairs to the gearbox and maintain smooth operation, especially in South African driving conditions.
