Things That Could Happen to Your Mercedes Benz 190e Radiator Fan
Driving with a hot engine can get you stranded on the road. To prevent engine failure due to overheating, your Mercedes Benz 190e radiator fan works overtime in pulling cool air onto the engine block. The radiator fan reduces the engine temperature, helping your car perform efficiently as it should. Sometimes, the radiator fan will stop working all of sudden. When that happens, you need to determine what it is exactly that to a radiator fan malfunction.
Fan refuses to turn on
A radiator or cooling fan adjusts its operation based on how fast your vehicle goes. If you're driving at high speeds, the fan clutch disengages the radiator fan, since there's sufficient air that flows through your car's engine from the outside. Once the fan clutch malfunctions, the radiator fan will not turn on. Replace the fan clutch to put the radiator fan back to work.
Fan operates intermittently
Your car's radiator fan is powered by the battery and the alternator. If your cooling fan works sporadically (frequently turns on and off), there might be some issues with the fan's wiring or fuses. Although the radiator dun will still function every now and then, it's best to change or repair the wiring and fuses before the problem becomes worse.
Fan does not efficiently cool the engine
Once a radiator fan becomes bad, your vehicle is at risk of overheating. When your car's engine swelters, there's a big chance that you might be stuck on the road. Conduct a visual inspection of your radiator fan. If the fan shroud is missing, your radiator fan can use only 50% of its total cooling capacity. On hot days, this could be a big problem, as the engine heats up faster than usual. Aside from checking the fan shroud, you also need to inspect if your vehicle is getting improper thermostat readings. If it does, then the radiator fan won't be able to cool the engine properly. Additionally, you need to make sure that the radiator itself is not clogged. A clogged radiator will hamper the flow of the coolant to the engine, and that increases the likelihood of your automobile overheating.
