What causes a car fan belt breaks quickly?

Fan belts or often referred to as V belts can break for several different reasons. Some common causes of car fan belt breaks include:

Prolonged Use

V belts that have been used for a long period of time can experience wear and tear due to repeated use.

Excessive Stress

If the V belt is too tight or too loose, it can cause excessive stress on the belt and eventually cause it to break. Stresses that do not match the manufacturer’s recommendations can damage the strength and tenacity of the belt.

Excessive Heat

Heat generated from excessive friction or high engine temperatures can accelerate V belt wear. This condition can be caused by problems with other components in the system, such as worn bearings or abnormal friction.

Poor Lubrication

Poor or lack of lubrication on the V surface of the belt can increase friction and heat, which in turn can lead to belt wear and breakage.

Incorrect Tension

Improper installation or inappropriate tension on the V belt can cause instability in belt movement and lead to faster wear.

Extreme Environmental Conditions

Extreme environmental conditions, such as high temperatures or exposure to certain chemicals, can damage the integrity of the V belt material.

Worn V Belts

An old and naturally aging V belt can lose its strength and elasticity, increasing the risk of belt breakage.

Improper Installation

Improper installation or not according to the manufacturer’s specifications can cause uneven tension and accelerate wear.

To prevent V belt failure, it is important to keep the drive system in good condition, follow the manufacturer’s recommendations for belt tension, and perform regular maintenance, including lubrication checks and replacement of worn V belts.

What happens if a fan belt breaks?

If the fan belt (V belt) on a vehicle or engine breaks, it can cause several problems and negative impacts on the performance of the engine and other systems. Some possible consequences include:

Engine Overheating

Fan belts are often used to drive the engine’s cooling fan. If the fan belt breaks, the cooling fan will not spin, and engine cooling may be compromised. This can lead to an increase in engine temperature, which in turn can damage engine components and even cause engine overheating.

Ineffective Pulley Rotation

The fan belt also drives other pulleys in the engine, such as the alternator pulley and power steering pulley. If the fan belt breaks, these pulleys will not rotate properly. As a result, the components associated with these pulleys, such as the alternator and power steering system, may not function properly.

Ineffective Battery Charging

If the fan belt drives the alternator, a belt break can stop the battery from charging. This can cause the battery to become discharged, which can ultimately render the vehicle or engine unable to start.

Loss of Power Steering Function

If the fan belt drives the power steering pulley, a belt break can make it difficult for the driver to control the steering due to the loss of power steering assistance.

Various Other System Problems

Fan belts can also be involved in moving other components, depending on the design and configuration of a particular engine or vehicle. So, a broken fan belt can cause various problems in other systems, depending on the belt’s specific role in the engine.

If you notice that a fan belt has broken, it is important to replace or repair it immediately. Ignoring this condition may result in further damage to the engine and other systems. It is always advisable to take the vehicle to a repair shop or mechanic for further repairs.

How to fix a broken fan belt

Tricking a broken fan belt is not a recommended solution. Fan belts play an important role in moving various important components in the engine, such as the cooling fan, alternator, and power steering pulley. Ignoring the decision to replace a broken fan belt can cause serious damage to the engine and other components.

However, in emergency situations where you cannot immediately replace a broken fan belt and need to reach your destination, you can try several ways to minimize the risk of further damage. However, it is important to remember that these are not permanent solutions and replacement of the broken fan belt is still required as soon as possible. Here are some steps you may be able to take:

Disable Related Components

If the fan belt breaks and drives some components (such as the AC compressor), temporarily disable or disconnect those components. This can help reduce the load on the system.

Watch Engine Temperature

If you cannot replace the fan belt immediately, pay extra attention to the engine temperature. Avoid running the engine for too long or under heavy conditions, as this may cause overheating.

Use the Vehicle Carefully

Avoid using the vehicle for long-distance travel or in heavy traffic conditions if possible. Only use the vehicle to reach the nearest destination or the nearest repair shop.

Pay Attention to Engine Indicators and Sounds

Watch for signs of overheating or strange sounds from the engine. If you hear unusual noises or see signs of trouble, stop and check the machine.

While the above steps may help in an emergency situation, replacing a damaged fan belt as soon as possible remains a top priority. Tinkering with the fan belt is not a recommended solution in the long run, as it can cause further damage to the engine.

How to Prevent Fan Belt Breaks

Here are some ways to prevent the fan belt from breaking on your car:

1. Routinely Check the Fan Belt Condition

Perform regular inspections to ensure the fan belt remains in good condition. Check for cracks, wear, or signs of material fatigue. If damage is found, replace the fan belt immediately.

2. Maintaining Proper Tension

Ensure that the fan belt tension matches the manufacturer’s standard. Tension that is too high or low can accelerate wear and increase the risk of breaking. If the tension is not correct, readjust it using a suitable tool.

3. Replace the Fan Belt Periodically

Fan belts have a certain lifespan. Typically, vehicle manufacturers recommend replacing the fan belt every 40,000 to 60,000 km. Replace the fan belt according to the recommended time interval to prevent further damage.

4. Check Related Engine Components

Check the components related to the fan belt, such as the pulley, alternator, and AC compressor. Make sure there are no worn or damaged components that can cause the fan belt to work not optimally.

5. Remove Dirt from the Fan Belt

Dirt, dust, and oil on the fan belt can accelerate damage. Make sure to clean the area around the fan belt so that no foreign objects interfere with the performance of the fan belt.

6. Check the Cooling System

Make sure the car’s cooling system is functioning properly. If the engine is overheating, the fan belt will be overstressed, which can cause damage. Check the radiator and coolant hoses to ensure there are no leaks or other problems.

7. Use a Quality Fan Belt

Use a good quality fan belt that matches the vehicle specifications. Low-quality fan belts wear out faster and have a higher risk of breaking.

By keeping the fan belt in good condition and performing proper maintenance, you can avoid serious damage to your vehicle and ensure the engine continues to function properly.
