This EPDM drive belt and tensioner kit is essential for the engine's accessory drive system, powering components like the alternator, water pump, and power steering. Manufactured from durable EPDM rubber, it offers superior resistance to heat, oil, and cracking compared to worn belts that may slip or break. Symptoms of a worn belt or faulty tensioner include squealing noises from the engine bay, loss of accessory function (e.g., no battery charging), or visible cracks and fraying on the belt.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A worn drive belt may initially manifest as a high-pitched squealing sound, particularly on startup or under load. If the belt continues to degrade, it can lead to intermittent loss of power steering or charging system warnings. A complete belt failure will result in the immediate cessation of all accessory functions, risking engine overheating and a dead battery.

Installation Tip

Before installing the new belt, carefully inspect the tensioner pulley for smooth rotation and proper spring tension; a seized or weak tensioner will damage the new belt. Ensure the belt is routed correctly around all pulleys according to the diagram to prevent misalignment and premature wear.

Service Note

Inspect the condition of all accessory pulleys, including the alternator, power steering pump, and water pump, for any signs of bearing wear or wobble.
