Mercedes-Benz Passenger A4639069800 Fan

Description

The Mercedes-Benz Passenger radiator fan (MPN A4639069800) efficiently draws air through the engine's cooling system to keep the motor operating at optimal temperatures. Installed in the engine bay, it improves heat dissipation and protects critical components. Measuring 90 x 90 x 110 mm and manufactured in Mexico, this fan offers reliable performance for modern passenger vehicles.

Key Features & Benefits

Basically, this fan’s job is to pull air through the radiator. The radiator is where your engine gets cooled down, and the fan helps move that cooling air when the car isn’t moving fast enough to get airflow naturally. It’s usually electrically powered, kicking on when the engine gets warm enough, or sometimes it’s belt – driven along with other engine components. Some newer vehicles have variable speed fans, adjusting how much cooling is needed. Think of it as part of your engine’s cooling system, which is absolutely vital. Coolant flows through the engine, absorbing heat. Then it goes to the radiator to release that heat. The fan ensures there’s always enough air moving through the radiator fins to get rid of the heat, even when you’re idling in traffic or going slowly. Without that airflow, the coolant can’t cool down properly.

Symptoms, Risks & Replacements

If this fan fails, things heat up fast. You’ll notice if it’s gone bad – usually your temperature gauge will climb higher than normal, especially when you’re not driving at speed. It can cause overheating, which can lead to serious engine damage – warped heads, blown gaskets, even a seized engine. It's a pretty critical part.
