Cheap Mercedes-Benz EQS Radiator Fan

The EQS is a fully electric vehicle with no internal combustion engine, so it does not have a traditional engine-driven or engine-cooling radiator fan of the kind found on petrol or diesel cars. The EQS does have thermal management systems for its battery, inverters and power electronics, but these use sealed liquid cooling loops rather than an open-air radiator with a fan in the conventional sense. If your EQS has a cooling fan fault, it is most likely related to the battery thermal management or HVAC system rather than a traditional radiator fan — confirm the exact component with your breaker or a Mercedes-EV specialist using your registration.

It is worth clarifying exactly what the breaker or supplier is describing, because 'radiator fan' on an EQS is not the same component as on a petrol or diesel Mercedes. What may be referred to colloquially as a radiator fan on the EQS could be a condenser fan for the air-conditioning system or a cooling fan associated with the high-voltage battery thermal circuit. These are quite different parts with different locations and functions, so make sure the part number and description match your specific fault before purchasing — confirm the exact component against your registration with the breaker.

Because the EQS (Z297 generation, launched in the UK from 2022) is a fully electric model without a conventional radiator fan, any cooling fan fitted relates to the battery or HVAC system rather than an engine. The Z297 generation covers 2022 onwards, and mid-production changes to ancillary components and their mountings are possible across those years, so whether a fan assembly from an earlier car fits a later one is not something we can guarantee — confirm compatibility against both registrations with the breaker.

Trim level — whether the car is a standard EQS, EQS 450+ or EQS 580 4MATIC for example — does not in itself determine which cooling fan assembly is fitted; what matters is the drivetrain variant, because the 450+ (rear-wheel drive) and 580 4MATIC (all-wheel drive) have different motor configurations which can affect thermal management components. Cosmetic trim differences such as interior specification or exterior styling packs are entirely irrelevant to this part. Always identify the exact drivetrain variant and confirm the part against your registration with the breaker rather than going by trim name alone.

If you have a fan-related fault on your EQS, the component is most likely either the air-conditioning condenser fan or a cooling fan within the high-voltage battery thermal management system, not a traditional radiator fan. Searching for 'EQS condenser fan' or 'EQS battery cooling fan' and quoting your full registration to the breaker will help them identify the correct part from a dismantled EQS of the same drivetrain configuration. Given the complexity of EV thermal systems and the possibility of software or pairing requirements, confirm with the breaker whether the specific unit requires any coding to your vehicle before buying used.
