KIEK rough-backed EPDM serpentine belts are manufactured using advanced SilentSync technology, ensuring squeak-free performance and significantly reduced belt slippage even under severe operating conditions. Reinforced with German Aramid (Kevlar) tensile cords, these belts demonstrate superior resistance to temperature fluctuations, aging, and chemical exposure. On average, KIEK EPDM belts deliver double the service life of standard market alternatives, offering exceptional resistance to engine oil, grease, and ozone.

Main Functions:

• Driving the Alternator: Converts crankshaft rotation into electrical power to charge the battery and power onboard electronics.
• Powering Power Steering Pump: Drives the hydraulic pump to provide steering assistance.
• Operating AC Compressor: Rotates the air conditioning compressor to maintain climate control functionality.
• Driving Water Pump (Engine Specific): In select engine layouts, powers the coolant pump to manage engine thermal cycles.
• Driving Auxiliary Accessories: Powers additional components such as vacuum or secondary air pumps depending on vehicle configuration.

Supplementary Documentation: Guide & Maintenance

1. Installation Guidelines:

• Select Correct Specs: Always verify exact belt length, width, and rib count (e.g., 6PK1575) prior to installation.
• Inspect Pulleys & Tensioners: Inspect crankshaft pulleys, idlers, and automatic tensioners for bearing play, worn grooves, or weak spring tension. A worn tensioner is the primary cause of belt squeal and premature failure.
• Correct Tension Setting: Ensure proper belt tensioning. Under-tensioning causes slippage, squealing, and heat build-up; over-tensioning damages alternator and pulley bearings.
• Clean Belt Path: Remove any oil, grease, or debris from pulley grooves before mounting the new belt.

2. Periodic Inspection:

Inspect the belt regularly for:

• Cracks, rib separation, fraying, or missing segments.
• Oil or coolant contamination (which degrades rubber compounds rapidly).
• Squealing noises during engine startup, steering maneuvers, or AC activation.

3. Failure Symptoms & Consequences:

• Symptoms: Battery warning light on dash, heavy/stiff steering, loss of AC cooling, engine overheating, or loud squealing under load.
• Consequences: Sudden snapping instantly disables power steering assistance and battery charging, potentially stranding the vehicle or causing engine overheating.
