Purpose and Compatibility with N55 Engine

The presented coolant thermostat is designed to work with the N55 gasoline engine installed in BMW F10, F12, F07 GT, and F06 series models. The OEM design guarantees proper fitment to the factory cooling system, correct port positioning, and proper interaction with the coolant circuit in the gasoline engine. This allows the part to be used as a replacement for the factory-installed thermostat without the need for installation modifications.

Technical Characteristics and Function in the Cooling System

The thermostat is responsible for controlling the flow of coolant between the small and large circuits, maintaining the engine's operating temperature within the optimal range. For N55 gasoline units, this is crucial for:

• stabilizing cylinder head and engine block temperature under load,
• maintaining appropriate operating conditions for the turbocharger and lubrication system,
• reducing the risk of overheating in city traffic and highway driving,
• ensuring correct operation of the engine control unit, which relies on data from the cooling system.

Thanks to its factory design, the thermostat works with original sensors and hoses, which facilitates installation and allows for maintaining the parameters specified by the vehicle manufacturer.

Application in BMW Vehicles and Installation Benefits

In BMW F10, F12, F07 GT, and F06 series vehicles with the N55 gasoline engine, a properly functioning thermostat is essential for the durability of the powertrain and user comfort. Replacing a worn-out part with an original thermostat from the Thermostats and Housings category allows for:

• restoring the correct engine operating temperature after symptoms of overheating or underheating have occurred,
• reducing excessive fuel consumption resulting from incorrect operating temperature,
• decreasing the load on other cooling system components, such as the radiator or water pump,
• maintaining compliance with the manufacturer's original specifications for thermal control.

A used OEM part is a good solution when the priority is to preserve the original system design while optimizing repair costs.

Condition, Origin, and Installation Aspects

The thermostat comes from a dismantled BMW vehicle and is offered as a used part, allowing for an economical repair of the cooling system while maintaining the original manufacturer's specifications. The part is intended for installation in place of the factory thermostat, using the original mounting points and existing coolant hose connections. Before installation, a standard leak check of the system and the use of new coolant compliant with the vehicle manufacturer's recommendations are advised.

Technical Support and Additional Information

If you have doubts regarding the selection of the thermostat for a specific N55 gasoline engine version, it is advisable to use the OEM part number or interchangeable numbers, which are detailed in the product's technical specifications. This allows you to verify compatibility with your specific vehicle configuration and avoid installation issues.
