Genuine Mercedes Battery Radiator
Genuine Mercedes 167-500-04-00 Battery Coolant Radiator Auxiliary Cooler
Genuine Mercedes OEM Battery Radiators
Modern Mercedes-Benz vehicles — particularly hybrid and plug-in hybrid models — rely on sophisticated thermal management systems to keep high-voltage battery packs operating safely and efficiently. At the heart of that system sits the battery radiator, a dedicated cooling component designed to regulate battery temperature under demanding driving conditions. When it comes to this critical part, Genuine Mercedes OEM components represent the only cooling solution engineered to the exact tolerances and specifications of your vehicle's battery system.
What Is a Battery Radiator and Why Does It Matter?
Unlike the engine's primary cooling radiator, a battery radiator is purpose-built to dissipate heat generated by the high-voltage battery pack found in Mercedes hybrid and electric-architecture vehicles. Lithium-ion battery cells are highly sensitive to temperature extremes — excess heat accelerates cell degradation, reduces range, and can compromise safety. A properly functioning battery radiator maintains the pack within the narrow thermal window that Mercedes-Benz engineers have determined is optimal for longevity and performance.

Why Choose Genuine Mercedes for Your Battery Radiator?
Aftermarket alternatives may appear dimensionally similar, but Genuine Mercedes battery radiators are manufactured to OEM standards — meaning they carry the same part numbers, materials, and flow specifications as the component originally installed at the factory. This matters for several reasons:
- Exact-fit design: Genuine parts are engineered to integrate seamlessly with the existing coolant lines, mounting brackets, and battery management system (BMS) sensors in your specific vehicle.
- Thermal performance: OEM cooling cores are validated to handle the precise heat load generated by Mercedes battery packs, ensuring consistent temperature regulation across a full range of ambient conditions.
- BMS compatibility: Mercedes battery management systems communicate with thermal components; a Genuine OEM radiator ensures there are no compatibility conflicts that could trigger fault codes or reduced performance modes.
- Durability and materials: Genuine Mercedes parts are built from materials that meet Mercedes-Benz's stringent corrosion and pressure resistance standards — critical for a component exposed to coolant chemistry over tens of thousands of miles.
- Warranty confidence: Installing a Genuine Mercedes part preserves your vehicle's factory warranty considerations and gives you the assurance that comes with a part backed by the manufacturer.
Which Mercedes Models Use a Battery Radiator?
Battery radiators are typically found on Mercedes-Benz plug-in hybrid (PHEV) and mild-hybrid models, including vehicles from the C-Class, E-Class, GLE, S-Class, and GLC lineups that feature the EQ Power or 48-volt mild-hybrid architecture. If your vehicle is equipped with a hybrid badge or a high-voltage battery system, a functional battery radiator is essential to keeping that system healthy for the long term.
For complete confidence in fit and function, always verify your vehicle's VIN and model year when sourcing a battery radiator. Browse the full Genuine Mercedes catalog for additional OEM parts that support your vehicle's cooling and electrical systems.
