How do you check the tightness of a V belt?

Observe it visually
Press on the belts
Listen for unusual noises
Check the tension indicator

The correct answer is: Press on the belts

Pressing on the belts is a practical method to check the tightness of a V belt. This technique allows the operator to feel the belt's tension directly. When you press on the belt, it should not deflect excessively; a properly tensioned belt will have some give but should maintain its integrity under pressure. If the belt feels too loose or can be pushed down significantly, it may indicate that it needs to be tightened to ensure proper function. Observing the belts visually can help identify wear or damage, but it does not provide a reliable assessment of the tension. Listening for unusual noises can indicate a problem, but it does not directly measure tightness. Checking a tension indicator, if available, is more precise and effective for determining tension, but it’s not as commonly accessible in all vehicles. Therefore, physically pressing on the belts gives a more immediate, hands-on assessment of their tightness.
