When to replace a broken serpentine engine belt?
Using a gauge to check for belt wear (Image courtesy of tradetrucks.com) Have the belt replaced whenever a related component is replaced (a broken belt is often associated with a damaged or seized pulley on one of the engine accessories).
What causes a serpentine belt to snap off?
In some more rare cases, belt misalignment can cause the problems. Whatever the case may be, make a replacement as soon as possible so the belt doesn’t snap.
What do you call the serpentine belt on a car?
What is a Serpentine Belt? A serpentine belt, also called an accessory belt, is the main engine belt that you see when you open up the hood of your car. These belts are easily identifiable by their distinct ridges that run the length of the belt on one side. The ridges help maintain grip when turning the accessory pulleys.
Is the water pump driven by the serpentine belt?
Another important device driven by the serpentine belt is the water pump. This is not always the case as on a lot of cars the water pump is driven by the timing belt. You should have this in mind so you don’t falsely “accuse” the serpentine belt for overheating.
What are the symptoms of a broken serpentine belt?
There are various symptoms that may indicate your car’s serpentine belt is wearing down, including: Squealing or chirping noises: When the serpentine belt starts slipping, it may begin to chirp or squeal . This sound indicates that there is belt stretch, low belt tension, or the pulley and belt are not working together correctly.

Is it safe to drive with a broken serpentine belt?
Do not drive your car with a broken serpentine belt. Your car will overheat because the serpentine belt drives the water pump (and without a serpentine belt, the water pump doesn’t circulate coolant through the engine and radiator) and it also drives the alternator which keeps the battery charged.
What causes my serpentine belt to break?
- C clutch pulleys.
- One of the idler pulleys get stiff under load due to lube being dried out or bad bearing.
- The alternator pulley’s bearings become stiff under electrical load or otherwise under belt tension load.
- C pulley gets stuff under load.
Can a broken AC compressor cause the serpentine belt to snap?
If the AC clutch bearing seizes while the AC compressor is not operating, the belt can snap then as well. Replacing the serpentine belt tensioner and idler pulley at the same time as the belt is always a good idea. They wear out too!
What are the symptoms of a failing serpentine belt?
Here are the symptoms of a failing serpentine belt: Cracks and wear. Serpentine belts are reinforced with cord and continue working even if the rubber is cracked. If you see any cracks, missing chunks, uneven wear or rib separation, its time for a new serpentine belt.
Can a gasoline car run without a serpentine belt?
On the other hand, gasoline cars will stall after 15-30 minutes if the battery is fully charged because they use much more electricity to keep running. However, if the serpentine belt drives the water pump, it doesn’t matter if it’s a diesel or a gasoline car – they both will overheat in a matter of minutes.
What happens if a serpentine belt is broken?
A broken serpentine belt leads to a sudden loss of power assist for the steering system, where the steering wheel all-of-a-sudden becomes very hard to turn. Imagine that happening in the middle of a busy intersection!
If the AC clutch bearing seizes while the AC compressor is not operating, the belt can snap then as well. Replacing the serpentine belt tensioner and idler pulley at the same time as the belt is always a good idea. They wear out too!
How much does it cost to replace a serpentine belt?
The replacement cost is only going to be between $100 and $200 in most cases. The belt itself will cost between $25 and $80 while the labor costs will probably be between $75 and $120. Taxes and fees will be added onto these prices too. The ease of accessing the serpentine belt will determine how much the labor costs are.
Can a car run without a serpentine belt?
However, these devices cannot function properly without the help of a serpentine belt. This one long continuous belt is the force that drives many of the engine’s peripheral devices. There is usually a belt tensioner or idler pulley to guide the belt as it moves. What is a Serpentine Belt? What is a Serpentine Belt?
When do you need to replace the idler pulley?
If it doesn’t, you probably need to replace the pulley. If you look at the belt when the car is running at idle, it moves quite smoothly along the system. When there is significant deterioration of pulley hardware, the belt moves from side to side. You will notice that it shakes or wobbles as it moves.
What happens to the idler belt when the car is running?
If you look at the belt when the car is running at idle, it moves quite smoothly along the system. When there is significant deterioration of pulley hardware, the belt moves from side to side.
What causes a serpentine belt to misroute?
It’s easy to misroute a serpentine belt if you can’t remember how it was positioned before it was removed. A sure sign of misrouting is if the belt seems to be too long or too short for the application, or if it won’t slip over the last pulley, or it is loose after it has been installed.
What makes a serpentine belt need to be replaced?
These include a misaligned power steering pump pulley, idler pulley (s), automatic belt tensioner pulley, water pump pulley (which may be due to wear in the pump shaft bearings), and even a worn or loose harmonic balancer.
If it doesn’t, you probably need to replace the pulley. If you look at the belt when the car is running at idle, it moves quite smoothly along the system. When there is significant deterioration of pulley hardware, the belt moves from side to side. You will notice that it shakes or wobbles as it moves.
Can a bad oil leak damage a serpentine belt?
A continuous oil leak can cause a serpentine belt to be completely damaged in as little as a week. In this case, the first remedy is to fix the oil leak. Bad spring-loaded automatic belt tensioner: Tension is essential to proper working of the serpentine belt.
If you look at the belt when the car is running at idle, it moves quite smoothly along the system. When there is significant deterioration of pulley hardware, the belt moves from side to side.
