Cost Savings

Checklist Tasks

• Inspect serpentine and timing belts for fraying or missing sections.
• Press belt between pulleys to check proper tension and avoid slippage.
• Look for cracks or splits on belt undersides indicating advanced wear.
• Examine hose ends for swelling or soft spots suggesting decay.
• Squeeze radiator and heater hoses when cool; check for brittleness.
• Check for oil or coolant leaks around hose clamps.
• Inspect for bulges or blisters on hoses, especially at bends.
• Ensure hose clamps are tight and properly positioned.
• Check if belts are aligned correctly on their pulleys.
• Listen for squealing on startup—a sign of slipping belts.
• Check for fine cracks on belt ribs with a flashlight.
• Record belt and hose service dates under the hood for tracking.
