Mercedes-Benz parts are sold by chassis code and build date more than by model name — a 2008 C300 (W204) and a 2015 C300 (W205) share nothing, and options like Airmatic suspension, 4Matic, Sport packages and parking sensors change the part. Many of the Mercedes parts we quote are for 2005–2015 C-Class, E-Class, GL and ML that have aged out of dealer pricing, so we match the part number to your VIN before quoting.
What’s different about Mercedes-Benz cooling and AC parts
- Radiators on ML, GL and R-Class carry the transmission cooler, and a failed cooler can push coolant into the transmission; the M272/M273 engines are known for leaking thermostat housings and water pumps that are sold as complete units with the housing.
- Electric auxiliary fans and the fan control module are frequent replacements on 2003–2012 models, and the E-Class and S-Class of that era use a fan clutch or a large electric fan depending on engine.
- AC compressors on newer models are variable-displacement with an electronic control valve, and many 2017-and-newer cars use R-1234yf refrigerant; the blower regulator behind the glovebox is the usual cause of a fan that only works on high.
