Mercedes Benz 190E Radiator Fan

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.

  • Simple Tips in Making Your Mercedes Benz 190e Radiator Fan Work More Efficiently 27 February 2013

    Your Mercedes Benz 190e radiator fan helps prevent your vehicle from overheating by allowing cool air to pass through the engine. Sometimes, the fan will have a difficult time functioning properly-there are times when it won't even turn on at all. You need to ensure that your car's radiator fan kicks on every time you need it, especially during hot summer days. You can do the following tips to help extend the life of your automobile's radiator fan.


    Clean the radiator fan regularly.

    A radiator fan with clean blades will efficiently blow cool air onto the engine. Most of the time, tar, grease, and other dirt become lodged on the blades, making the fan less useful in cooling the engine. By using a pipe cleaner, you can displace the grime stuck on the fan blades and other small parts. Alternatively, you can use a rag dipped into degreaser to help dislodge any hard-to-remove substances from the radiator fan blades.


    Install a fan shroud.

    A shroud is a funnel-shaped device usually made from plastic or metal and is attached behind the radiator. The shroud helps direct the flow of air onto the engine. Without the shroud, air will flow in all directions, rendering the work of your radiator fan futile. Some people remove the shroud, thinking that it's just a useless piece of metal or plastic. If it has been mistakenly removed from your radiator fan, put it back right away. All the parts that came with the vehicle have their own purposes, so removing them will certainly effect the performance of your automobile.


    Check the fuses and wiring on the fan.

    Broken wires and fuses can hamper the delivery of power from the battery or alternator to the cooling fan. To maximize the capacity of your radiator fan, you need to replace any damaged fuses or wires connected to it. You can spot check the wires for nicks or use a voltmeter to check the electricity. For the fuses, a fuse multimeter will help determine if there are any blown or bad fuses connected to your car's radiator fan.
