3100402 — V-Ribbed Fan Belt 3100402 12Pk2139 For Cummins Engine Isx15 Volvo Truck Vn Vnl

This V-ribbed fan belt, also known as a serpentine belt, drives essential engine accessories such as the alternator, water pump, and air conditioning compressor. It is constructed from durable, high-tensile rubber compounds designed to withstand extreme temperatures and flexing, unlike a worn belt that may show cracks, fraying, or glazing. Operators will typically observe a loud squealing noise from the engine bay, especially upon startup or acceleration, and may notice a lack of accessory function if the belt fails.

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 failing fan belt often begins with a high-pitched squealing noise, particularly noticeable during engine startup or when accessories are under load. If the belt continues to degrade, it can lead to a loss of power to accessories like the alternator and water pump, causing battery discharge warnings and engine overheating. Complete belt failure will result in a loss of all accessory functions, potentially disabling the vehicle.

Installation Tip

Always release tension on the belt tensioner slowly and carefully to avoid sudden release or damage to the tensioner mechanism. Ensure the new belt is correctly seated in all the pulley grooves before applying tension.

Service Note

Inspect the condition of all accessory pulleys and the belt tensioner for proper operation and wear when replacing the V-ribbed fan belt.
