When driving your car, you can suspect that the engine belts are not working properly if you hear chirp or squealing sounds. Deficient belts reduce the power of the engine, have steering problems and other problems. Most modern cars only have one or two belts. There are mainly three types of belts: fan belt, alternator belt and serpentine belt. The serpentine belt is a single continuous belt that powers engine-installed components such as the alternator, power steering pump, water pump, and compressor air conditioner. An idler pulley or spring-loaded tensioner supports this belt to prevent drivers from slipping. The timing belt for motors with multiple camshafts is located outside the engine but is routed over multiple gears. This belt is easy to manufacture and assemble because lubrication does not require oil. The normal period of replacement is from 60,000 to 100,000 miles.

The drive belt is made of sturdy rubber and degrades when it comes into contact with petroleum products or other chemicals. It gets damaged due to loss of engine cooling which quickly renders the vehicle unusable. Although the belt usually lasts up to 75,000 miles, replacement is recommended at the 45,000-mile mark. The toothed, reinforced belt used to drive the camshaft via a sprocket to a crankshaft is known as the timing belt. This belt ensures synchronization of the engine's camshaft, crankshaft and distributor. It also maintains accurate synchronization required to keep the engine’s valves and pistons moving in sync. Its hoses and steel lines transfer coolant, brake fluid and fuel throughout the vehicle. Over time, these parts may crack, rust or leak. In general belts make less noise. They stretch and loosen and cause whining noise before breakage. This is an indicator of a failing belt and that it requires replacement. It is easier to replace a belt because it takes less time and less labour charges. Many engines have a timing chain instead of a belt.

After 150,000 miles, a timing chain will require replacement. It is less likely to break or damage, but tends to begin stretching. A severe stretched chain may jump teeth, have problems with timing and may damage the valves of the engine. It is expensive and time-consuming to replace a worn out timing chain. If either belt breaks, it will stop the vehicle. The engine shuts off after a timing belt breaks and you won't be able to restart it. Even if you can restart the engine after breaking an accessory drive belt, if it does not drive the alternator, you won't be able to get far. Without the alternator, you'll end up relying on the battery's electrical power that won't last long.
