When to Replace
Replace this belt if you notice cracking, glazing, frayed edges, missing cog material, excessive stretching, or persistent squealing during operation. A worn or loose belt reduces power steering pump output and can cause inconsistent or heavy steering. Inspect the belt at each seasonal service.
Installation Notes
During belt replacement, inspect the power steering pump pulley, crankshaft pulley, mounting bracket, and belt alignment for wear or damage. Set belt tension according to the Volvo Penta service specification for the engine and recheck tension after the first hour of operation.

Technical FAQ
Is this the only belt on these engines?
No. Volvo Penta gasoline engines typically use multiple belts for different accessories. Part 3858462 is specifically the power steering pump belt — other belts on the same engine (alternator, raw-water pump) have different part numbers.
Will the older numbers 3853331 or 960336 still work?
Those are superseded numbers that 3858462 replaces. Order using 3858462 as the current active number to ensure you receive the correct part.
How do I know if my belt tension is correct?
Use the deflection method specified in your Volvo Penta service manual. A correctly tensioned belt should have minimal deflection under moderate thumb pressure at the longest unsupported span. An overly tight belt accelerates pulley bearing wear; a loose belt slips and reduces steering assist.
Can I use the Sierra 18-15450 instead?
Sierra 18-15450 is an aftermarket reference for this application. If you prefer the OEM part, use Volvo Penta 3858462. Sierra 47-15450 is available here if you prefer the aftermarket option.
Parts Desk Insights
The most common mistake with this belt is ordering an alternator or raw-water pump belt when the customer actually needs the power steering belt — they’re all V-belts on the same engine and look similar. Asking the customer which accessory lost performance (steering feel vs. charging vs. cooling) quickly narrows it down. Squealing on turns is the classic symptom for a worn power steering belt specifically.
