Overview

This is a genuine OEM-spec Engine Coolant Thermostat Heat Management Module for BMW, carrying part number 11538642560. The heat management module integrates the thermostat function into a single, electronically controlled assembly, allowing the engine's cooling system to regulate coolant temperature with greater precision than a traditional wax-element thermostat. Proper operation of this module is critical for maintaining optimal engine operating temperature, protecting against overheating, and supporting BMW's map-controlled cooling strategy for fuel efficiency and emissions compliance.

Compatible sold examples confirm fitment across a wide range of modern BMW platforms equipped with the 2.0L B46 and B58 four- and six-cylinder engines, including the G20/G21 3 Series (330i), G30 5 Series (530i), G01 X3, G02 X4, G05 X5, G06 X6, and Z4 models. Always verify against your vehicle's specific build date and engine code before ordering.
