Description
BMW B58 thermostat.
Control the flow.
This BMW B58 thermostat is a brand new aftermarket B58 heat management module for selected 3.0L turbocharged six-cylinder petrol models. It replaces the assembly identified by reference 11537642854. Before ordering, match your original number, connector, hose outlets and vehicle VIN.
Choose a replacement using the original part, not the B58 engine name alone. Later engine versions can use a different module. Our Australian team can help check the details before you plan your repair.
B58 heat management module.
Every detail matters.
The electronic assembly manages coolant flow within the engine cooling system. However, a coolant leak or temperature warning does not identify the failed part on its own. Have the cooling system diagnosed first, then compare the removed module with the product photographs.

Your BMW B58 thermostat.
Our local support.
Clear part references and detailed photos help you choose the right replacement. In addition, our Australian team can assist with fitment questions and after-sales support. Send us the VIN, original number and photos if anything differs.
This is a Parts Factory Australia aftermarket part, not a genuine BMW product. BMW names and OE references identify the intended application only.
Install the B58 heat management module
with the right procedure.
Professional installation is recommended. First, confirm the fault and replacement reference. Then follow BMW’s model-specific removal, installation and cooling-system bleeding procedures. Any required diagnostic adaptation or calibration must also be completed.
Use the coolant specification and tightening instructions appropriate to your vehicle. We do not supply coolant or tools with this assembly. Finally, check the system for leaks and verify correct operation before returning the vehicle to service.
Replacing a thermostat will not resolve every cooling-system fault. Professional installation and receipts are required under our replacement warranty terms.

Is this a genuine BMW part?
No. It is a Parts Factory Australia aftermarket replacement. The BMW name and OE numbers are used only to explain compatibility.
