Drive Belt Inspection & Replacement Checklist

This drive belt inspection and replacement checklist ensures accurate condition assessment and proper installation of serpentine, V-belts, and multi-rib belts using current EPDM wear measurement techniques. Modern EPDM belts show little visible cracking even when worn to replacement threshold - requiring belt wear gauge measurement rather than visual inspection alone. Aligned with Gates, Dayco, and Bando belt service guidelines and OEM replacement intervals.

Industry: Automotive Service
Frequency: Every 60,000-100,000 miles / Per Complaint
Estimated Time: 30-60 minutes
Role: Service Technician
Total Items: 28
Compliance: Gates Belt Service Guidelines, Dayco Belt Replacement Standards, OEM Drive Belt Replacement Intervals, ASE A1/A6 Belt Service Procedures, SAE J637 Belt Standards

Belt Condition Assessment & Measurement

Proper EPDM belt wear measurement requires a belt wear gauge - visual cracking inspection alone is insufficient for modern belts.

Belt wear gauge used to measure rib depth - at or below replacement threshold?
Belt length/stretch measured - within elongation tolerance?
Belt back surface not glazed or cracked (old EPDM sign of heat damage)?
Belt ribs not chunking, fraying, or showing chunk-out on rib edges?
Belt free of oil or coolant contamination?

Tensioner & Idler Pulley Inspection

Inspect automatic tensioner operation and all idler pulleys. Tensioner and idler failure is the #1 cause of new belt failure.

Automatic tensioner arm moves freely through full range without binding or damping issues?
Tensioner spring tension adequate - tensioner holds belt at correct angle?
Tensioner pulley bearing smooth and quiet with no wobble?
All idler pulley bearings smooth, quiet, and free of wobble?
All pulleys in same plane (serpentine) - no edge wear indicating misalignment?
Tensioner pivot bolt torqued to specification after any tensioner service?
Belt noise source identified before replacement if noise was reported?

Accessory Component Drive Inspection

Inspect all belt-driven accessories for bearing condition that affects belt life and system reliability.

Alternator pulley (including overrunning alternator decoupler if equipped) smooth and functional?
A/C compressor clutch/pulley bearing smooth with no wobble?
Power steering pump pulley tight and smooth (if belt-driven)?
Water pump pulley tight with no wobble indicating bearing failure?

Belt Installation & Routing Verification

Verify correct belt routing around all pulleys using vehicle-specific routing diagram.

Vehicle-specific belt routing diagram referenced (label in engine bay or service data)?
Belt ribs properly seated in all pulley grooves with no riding on top of rib?
Final belt tension verified (tensioner at mid-range or manual tension within specification)?
Engine rotated 2+ times by hand and belt tracking verified on all pulleys?
Startup noise check - no squealing, chirping, or slapping after new belt installation?
Belt replacement documented on repair order with next service interval noted?

Related Services & Customer Communication

Identify and communicate all belt-related services for maximum component longevity.

Automatic tensioner assembly replaced with belt (recommended at 100k+ mile intervals)?
Idler pulleys replaced or inspected with documented condition?
OEM or OEM-equivalent quality belt installed (not economy aftermarket)?
Customer explained what serpentine belt drives and why replacement was due?
Photo of old belt condition taken for documentation?
NHTSA recall check performed for belt/tensioner-related recalls on this vehicle?
