The Mercedes-Benz GL450 Alternator is the miniature giant that transforms the engine's rotation into the uninterrupted flow of electricity that will keep the SUV battery charged and all the electronic luxuries of the car alive when traveling in the city or on the highway. It is enclosed in a lightweight two-piece aluminum case that spins on two sealed bearings to provide whisper-quiet service, and internal fans move fresh air over heat sinks, ensuring that heat does not steal performance, which is a design choice that could be attributed to Mercedes-Benz durability. A heavy belt connects it to the crankshaft whereby the rotor accumulates energy, which is immediately smoothed into direct current, which is friendly to the battery, using a diode-packed rectifier. Newer models attach their voltage regulator to the Powertrain Control Module, which is an upgrade that improves the control of voltage, enhancing reliability, but the component remains compatible with older models that applied a self-contained regulator, so the Alternator can be attached to the entire GL450 production line. The fact that it has such wide compatibility is important, as it means that Mercedes-Benz owners will experience the same level of consistency in terms of charging their vehicle, regardless of whether they have a first edition or the facelifted version of the GLS. When installed, the Alternator can easily be applied to feed power-hungry options such as the heated seats, air suspension and multi-screen infotainment systems without causing a battery voltage drop, a feature that directly translates into safer drives at night, better sensor data and quicker engine starts during winter. Its high idle output is also enjoyed by drivers, who do not have flickering lights in traffic, and it also extends battery life. Supported by the tradition of the brand in making refinements, this part demonstrates the way Mercedes-Benz is capable of combining efficiency and power, giving any owner of the GL450 reliable performance and calmness.
