How often should you change alternator belt?
Serpentine belts are built to last – much longer than before because of advancements in rubber technology. Under ideal conditions, a belt should stick with you for an average of 60,000 to 100,000 miles. Pretty impressive. However, some belts are manually tensioned and may need to be adjusted.
Consequently, how much should it cost to replace a timing belt?
The majority of the cost is labor, because many parts need to be removed from the engine to gain access to the belt. A typical timing belt will only cost between $25 and $50, but the repair takes at least a few hours. The labor cost to replace a timing belt can range from $200 – $900.
How much does it cost to replace the belt in the car?
Know what price you should pay to get your vehicle fixed. The average cost for a serpentine belt replacement is between $76 and $164. Labor costs are estimated between $35 and $100 while parts are priced between $41 and $64. Estimate does not include taxes and fees.
Symptoms of a Faulty Timing Belt
- 1) Rough Idling of the Engine. There are teeth on the timing belts which grip gears as they're rotating various engine parts and components.
- 2) Misfire of the Engine.
- 3) Smoke from the Engine.
- 4) Oil Pressure Decline.
- 5) Pistons or Valves That Are Broken.
If the timing belt snaps, they run into each other, causing bent valves (most common), cylinder head or camshaft damage, and possibly piston and cylinder wall damage. While it is possible that no damage could occur from a snapped belt on an interference engine, such a case is unlikely.
Essentially, it coordinates the rotations of the camshaft and crankshaft so the engine's valves and pistons move in sync. The expected lifespan of your timing belt is specific to your car and engine configuration, usually between 60,000 and 100,000 miles.
A drive belt (also can be called accessory drive belt, serpentine belt, alternator belt, or fan belt) is a rubber belt that powers the engines accessories. This always includes the alternator and AC compressor. The timing belt drives the cam shafts of the engine and thus, the valves and timing of the engine.
The average cost for a serpentine belt replacement is between $76 and $164. Labor costs are estimated between $35 and $100 while parts are priced between $41 and $64. Estimate does not include taxes and fees.
1. Grinding or squeaking noise from the belts or tensioner. The most common symptom of a bad or failing drive belt tensioner is noise from the belts or tensioner. If the tensioner is loose the belts may squeak or squeal, especially when the engine is first started.

Symptoms of a Bad or Failing Serpentine/Drive Belt
- 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. If the serpentine belt completely fails and breaks, then your car will break down.
- Engine overheating.
- Cracks and wear on the belt.
6 Symptoms of a Failing Alternator
- The indicator light. It's quite likely that your vehicle is equipped with a warning indicator light in the dashboard titled "ALT" or "GEN."
- Headlights are dim or flickering.
- Other electrical failures.
- Strange noises.
- Car stalls or has difficulty starting.
- Battery dies.
The make and model of your vehicle will determine the exact time it takes to replace the alternator, but usually, one to two hours is sufficient.
A serpentine belt, also known as a multi-vee, poly-v, or multi-rib belt, is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator, power steering pump, water pump, air conditioning compressor, air pump, etc.
Maintenance schedules for various makes of vehicles differ on how often the air filter should be changed. On most Chevrolet engines, for example, the recommended change interval is every 45,000 miles, but Ford says it should be done every 30,000 miles on many of its engines.
Many car owners may wonder how often to replace a timing belt. The old rule was every 60,000 miles. As technology has improved, many manufacturers recommend intervals up to 100,000 miles. To be safe you should check what the vehicle's manufacturer recommends and stay within that mileage.
Serpentine belt problems usually result from one of three causes: a defective belt tensioner; misalignment of a pulley; or, defective bearings in the tensioner, idler, or one of accessories driven by the belt (including the water pump). Excessive cracking: Other than severe old age, defective tensioner.
V-Belts usually should be inspected for wear after 3 years or 30-40,000 miles of use. According to belt manufacturers, failure rates rise sharply after 3 years of service. Replacing V-belts every 3-4 years can minimize the risk of sudden belt failure. Most cars on the road today have only one belt, a serpentine belt.
Idler pulleys are engine pulleys that are responsible for guiding and tensioning the engine drive belts. The engine drive belts are routed in a specific manner around the various engine accessories, such as the alternator, water pump, power steering pump, and AC compressor.
Checking Your Coolant and Brake Fluid. As a rule of thumb, you should check your coolant level twice a year, once before summer and once before winter. Check your brake fluid every oil change or at least once a year.
Your engine has a number of mechanical accessories attached to it, such as an alternator, water pump, power steering pump and an air conditioner compressor. A drive belt is the part that drives all these accessories. When a car has only one drive belt, it might be called a serpentine belt.
Typical costs: Hiring a mechanic to replace a serpentine belt typically costs about $60-$200 or more. This includes $25-$75 for the belt plus half an hour to an hour of labor, at $75-$120 per hour. The job could even take longer on some vehicles, if the belt is difficult to access or install quickly.
