🔧 Product Description

This is a genuine Volvo Penta cooling system pulley, part number 1542235, designed specifically for use with water pump 3580777. It mounts to the pump and carries the drive belt that turns the pump rotor, keeping coolant circulating through the engine. Because it is matched to one specific pump assembly, confirm your pump number before ordering to ensure correct belt alignment and drive geometry.

🔌 Function

The pulley transfers rotational drive from the engine belt to the circulation water pump so coolant is pumped continuously through the engine. Correct pulley condition and alignment are essential for stable belt tension and reliable cooling flow.

⚠️ Common Signs of Failure

• Worn, grooved or corroded belt grooves causing belt slip and squealing
• Visible wobble or run-out indicating a bent pulley or worn pump bearing
• Rapid or uneven belt wear and black belt dust around the pump area
• Cracks, chips or flaking in the pulley face or hub
• Overheating or reduced coolant circulation caused by intermittent belt drive

🛠️ Service Notes

• Inspect the belt running surfaces before fitting — a pulley with glazed, scored, pitted or rust-roughened grooves will chew through a new belt in very little running time
• Check that the pulley runs true and that its bearing or bush turns smoothly with no roughness or side play; fit a new belt whenever a pulley is changed
• Confirm that every pulley in the drive lies in the same plane and that the belt profile matches each groove — misalignment shows up as belt dust, squeal or a worn belt edge and will destroy a new belt quickly
• Fit onto a clean, dry, burr-free shaft or hub face and tighten the retaining fasteners in the sequence and to the figures given in the workshop manual for your engine
• Turn the engine over by hand before starting to confirm the belt is fully seated in every groove and that nothing fouls, then recheck belt tension after the first running period
