Way to Identify the Failed Air Pump Belt in car

Way to Identify the Failed Air Pump Belt in car

Air pump is an emission component found in the car with V8 engines.

Used for reducing emissions and driven by the engine accessory belt.

Air pump belt can drive the pump as well as an entire air injection system.

Small issues in the belt quickly affect the engine performance.

Cracks on belt

When you notice cracks on the pump belt, replace it immediately.

Cracks will develop on the ribs of the belt for below reasons: • Contact with the pulleys

• Constant exposure to extreme heat

Thus, the cracks permanently damage the air pump belt.

Weaken its structural integrity and susceptible to failure.

Rubber is missing on belt

AC belt of the car can wear out and develop cracks on them.

Weaken belt can break off the entire chunks of the rubber.

Rubber has broken off at the ribs of the belt considerably.

Along with the rubber, the belts are more likely to break.

Scuffs outside the belt

Scuffs along the edges or outsides of the belt can fail the AC belts.

Usually, the scuffs build up outside the belt for below reasons:

• Misaligned belt on the pulley • Belt contact with some debris • Contact with components of the engine.

Scuffs may cause threads from the belt and loosen it.

Loose threads outside the surface/edge indicate AC belt replacement.

Conclusion

AC belt directly drives the AC compressor for its efficient function.

Failed belt may completely disable the AC system and need replacement.
