What is the fan belt connected to?
A fan belt connects the engine cooling fan to the alternator and crankshaft pulley. Belts are also used to power components such as the air conditioner compressor, the power steering pump and the water pump.
Is the fan belt attached to the alternator?
When an alternator is actively charging the battery, it is actually spinning inside the vehicle. There is something called an alternator belt (also called a serpentine belt) which wraps around a pulley or multiple pullies that is connected to the alternator.
What are the signs of a bad fan belt?
If you suspect your serpentine belt is failing, watch out for the following symptoms:
- Squealing noise from the front of the vehicle. If you notice a squealing noise coming from the front of your vehicle, it could be from the serpentine belt.
- Power steering and AC not working.
- Engine overheating.
- Cracks and wear on the belt.
What happens if fan belt breaks?
This can lead to a sudden lost of power assist for the steering system, leading to the steering wheel all-of-a-sudden becoming very hard to turn. A broken serpentine belt may stop the water pump from circulating coolant through the cooling system, causing the engine can overheat.
Is the fan belt the same as the timing belt?
Don’t get confused—a serpentine belt is not the same thing as a timing belt. The serpentine belt and timing belt have very different functions in your vehicle. The timing belt is located inside the engine and keeps the crankshaft and camshaft in sync.
Is it easy to fit a fan belt?
Overview: Fan belt replacement Serpentine belt replacement is easy because today’s automatic drive belt tensioners eliminate the need to loosen bolts or pry components into position for retensioning. When the belt ribs are seated into the pulley grooves, release the tensioner and you’re done.
Can you drive without a fan belt?
Under no circumstances can you drive a vehicle without a serpentine belt because the serpentine belt serves the important function of delivering antifreeze to important parts of the engine. The serpentine belt drives the water pump, and without it, there is insufficient coolant flow to maintain the engine temperature.
How much does it cost to fix a fan belt?
A typical serpentine belt start at around $25 and goes up to $75 at most. If you know some car repair basics, you could change the belt yourself, and it may save you paying labor charges somewhere between $75 and $120. All together, you’re looking at around $100 to $195 to replace your serpentine belt.
How do I know if my belt needs replacing?

What happens if fan belt breaks while driving?
If a serpentine belt is broken, it can lead to a sudden loss of power assist for the steering system. This happens because the serpentine belt keeps the water pump circulating coolant, also known as antifreeze, through the cooling system. This means that the engine can overheat anywhere, including the highway.
How does the fan belt work in a car?
The fan belt is used to transfer rotational power from one place to another in the engine. It works in a very similar way to the timing belt; the only real difference is that it connects a different set of rotating shafts together.
Which is the correct definition of a fan belt?
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. It is usually V-shaped in cross section with the point of the V fitting into a groove in the pulley”.
What happens when a radiator fan belt breaks?
When a radiator fan belt breaks, the entire car engine can cease to work. A dead battery is a high possibility. In addition, the break may cause serious damage to the alternator, radiator, steering pump and other parts the belt controls.
What’s the difference between a fan belt and a serpentine belt?
While some older cars have radiator fan belts, most modern cars have a serpentine belt, which serves the same function but controls many more engine parts. There are warning signs that indicate a fan belt or serpentine belt needs to be replaced. Often, a worn belt makes a squealing noise for 1 or 2 minutes after the engine starts.
