20457273 — V-Ribbed Belt A/C 20457273 6Pk1620 For Cummins Engine Isx Volvo 850 960

This V-Ribbed Belt is designed to drive essential accessories such as the alternator, power steering pump, and air conditioning compressor from the engine's crankshaft. Manufactured with high-grade rubber compounds and reinforced cords, it offers superior durability and resistance to heat and wear compared to a worn or cracked belt. A failing belt will typically produce a loud squealing noise, especially upon startup or acceleration, and may eventually lead to a loss of power steering or air conditioning.

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

The most common symptom of a worn V-Ribbed belt is a loud squealing noise, particularly noticeable during engine startup or when accessories are engaged. If left unaddressed, the belt can fray, crack, or completely break, leading to a loss of power steering, battery charging issues, and a non-functional air conditioning system. The ultimate consequence is the potential for the engine to overheat due to the non-operation of the water pump, if belt-driven.

Installation Tip

Always release tension on the belt using the tensioner pulley before attempting to remove or install the new belt. Ensure the new belt is correctly seated in all the pulley grooves to prevent slippage and premature wear.

Service Note

Inspect the belt tensioner and all accessory pulleys for proper operation and signs of wear or damage when replacing the V-Ribbed belt.
