Diagnosis and Common Symptoms
A failing radiator or cooling fan assembly on the W221 S-Class typically presents with coolant temperature fluctuations, an illuminated engine warning light, or a visible drop in coolant level without external leaks. Common fault codes logged by the SBC/ME control units include coolant temperature sensor implausibility, radiator fan control module faults (N9/4 or A4/2), and low coolant level warnings on the instrument cluster. Drivers often report the auxiliary transmission oil cooler underperforming, causing elevated automatic transmission temperatures during heavy traffic or towing. A cracked end tank, clogged fin core, or a seized/noisy electric fan motor are the usual mechanical culprits, frequently accompanied by AC system inefficiency since the condenser sits in front of this assembly. Left unresolved, these issues can lead to overheating, transmission damage, or air conditioning compressor strain due to reduced heat exchange.
