Which items are inspected on the engine belt during preventative maintenance?

• A. Cracks and bolts only
• B. Belt color and length
• C. Cracks, Belt Wear, Belt Tension
• D. Oil leaks and belt temperature

Answer: (C)

Preventive maintenance on the engine belt centers on its condition and how it drives the accessories. Cracks indicate aging and a real risk of sudden belt failure. Visible belt wear—glazing, fraying, or thinning—shows the belt is losing its integrity and may slip or break sooner. Proper belt tension is crucial to prevent slipping while avoiding excessive bearing load from an over-tight belt. Together, these checks—cracks, wear, and tension—directly assess belt health and whether it needs replacement or adjustment. Other checks like color or length aren’t reliable wear indicators, and oil leaks or belt temperature point to related issues rather than belt condition itself.
