We clarify appearance, function, and typical location of each type. Look up “fan belt” in any modern automotive dictionary, and you’ll typically find a definition that reads, “An endless belt used to transmit power from a crankshaft-driven pulley to a pulley driving the fan, alternator, or other engine accessory.
What is a fan belt in a car?
The fan belt is a flexible synthetic rubber band which connects various engine components together. It has a long series of teeth running along the inner surface of the belt which generate traction, allowing it to grip to the shafts it connects and keeping it from slipping off at any point.
What is a fan belt called?
The serpentine belt is a long rubber belt that transports power to the engine accessories—the alternator, power steering pump, air conditioning compressor and (sometimes) the water pump. You may have heard a serpentine belt referred to as a fan belt or accessory belt.
Where are the pulleys on a car located?
An engine pulley is mounted to the engine of an automobile and drives all belts. Your car probably has a serpentine belt which is a continuous belt used to drive multiple peripheral devices. Those devices include an alternator, power steering pump, water pump, air conditioning compressor and the radiator fan.
Why does my car’s fan belt make noise?
If your fan belt breaks or falls off, these components will eventually fail, potentially leading to much bigger issues. A.K.A: it’s important. Why Is It Making Noise? The sound of a squeaky belt in your vehicle’s engine is usually because the rubber belt is slipping on the metal pulley.
What’s the difference between serpentine belts and fan belts?
Fan Belt: “Fan belt” is kind of a colloquialism these days. Fan belts are more commonly found in vehicles built before the 1990’s when serpentine belts started to replace them. In theses older models, “fan belts” are usually paired with other belts that together form a “V” shape around your drive pulleys and gears.
How does a belt pulley in an engine work?
How Belt Pulleys Work. Most pulleys are driven by a main crank pulley, which is bolted onto the crankshaft. When the engine is operating, the crank pulley rotates, transferring motion to the other pulleys by means of the serpentine belt or v belt. Sometimes, the camshaft has power takeoff, with the camshaft connected to the crankshaft by means…
What kind of pulley drives the car engine?
There are a multiple of other belt driven devices under the hood. An engine pulley is mounted to the engine of an automobile and drives all belts. Your car probably has a serpentine belt which is a continuous belt used to drive multiple peripheral devices.
What happens when the fan belt on a car breaks down?
As your fan belt or serpentine belt breaks down and frays, it won’t be able to turn the water pump consistently, which slowly defeats the engine’s cooling systems and causes the temperature to rise more than it should.
What causes a fan belt to make noise?
Misaligned tensioner or pulley: If everything isn’t aligned correctly within the belt system, it will cause a slip and begin to make noise. Improper Installation: When installed, the belt must be tensioned appropriately and then re-tensioned again after a few minutes of running the engine.
How to choose a pulley that fits your V belt?
So I did the math, and if a picture speaks a thousand words, what follows will save us all some time.
