Engine belt and air conditioner for Changan Hunter
It is important to change the engine belt if you see any of the following signs of damage:
1. Presence of random cracks
- Appearance: Small cracks are visible along the machine's belt.
- The reason: Continuous exposure to high temperatures and stress resulting from bending around the pulleys. As a general rule, if cracks appear at a distance of 1 or 0.2 cm, then 80% of the service life has ended and the machine belt must be changed.
2. Pieces of rubber falling off
- Appearance: Pieces or fragments of rubber material falling off the machine belt.
- The reason: Heat, age, and stress are the main contributing factors.
3. Wear and tear on the belt at the edges
- Appearance: There is wear and tear on the ends of the engine belt.
- The reason: poor alignment, a new machine belt on worn-out pulleys, lack of tension, or a combination of these factors.
4. Wear and tear on the rear of the belt
- Appearance: The back of the tread looks shiny and in advanced stages it wears away until the threads are exposed.
- The reason: The belt is not tightened correctly, it is vibrating between two pulleys, or it is coming into contact with a foreign object.
5. Separation of rubber pieces
- Appearance: Pieces or parts of rubber material have separated from the front part of the machine belt.
- Reason: The machine belt was not properly installed on the pulleys.
6. Uneven wear on the front part
- Appearance: Uneven wear on the front ribs of the engine belt.
- The reason: The presence of a foreign object, such as a pebble, in one of the pulleys.
7. There are small holes in the belt.
- Appearance: Small holes and bumps appear on the back side of the walkway.
- The reason: Gravel accumulates between the engine belt spokes.
8. Separation of the belt threads at the ends
- Appearance: The edge thread is worn away and separated, and the ribs are removed.
- The reason: Poor alignment of the engine belt pulleys.
9. Oil pollution
- Appearance: The motor belt surface is flaky, sticky, or swollen.
- The reason: Oil and grease are the worst enemies of rubber compound as they weaken the belt and make it soft and spongy.
10. Erosion of the ribs of the front section
- Appearance: Signs of wear appear on the ribs and this can be detected using a belt wear gauge.
- Reason: The engine belt has reached the end of its service life.

When should the engine belt be changed?
The engine belt can be changed every 100,000 km as a preventive maintenance, or the owner's manual can be consulted to determine the exact change interval. However, in some cases, the engine belt must be changed when certain visible signs appear.
Why should the engine belt be changed?
The engine belt in your car can wear out over time, so manufacturers determine the lifespan based on the distance traveled or the time at which the engine belt should be changed.
What caused the engine belt to break?
Friction, heat and corrosion are the main reasons behind engine belt failure, and this applies to many car components. This is why routine maintenance is important.
In general, if you notice any of the above signs that your engine is about to fail, it is important to act quickly.
Ultimately, your car's engine belt plays a crucial role in overall operation, and if it fails, you won't be able to drive normally; in fact, your car will only run for 20-90 minutes.
