Shop BMW 525i Replacement Accessory Belt Idler Pulley

The BMW 525i would not get very far out without the accessory belt idler pulley. This pulley is designed to regulate the belts that are connected to the crankshaft of the engine. It is mounted with supports and is made of a sheave and a wheel. The sheave is the pulley part of the accessory belt idler pulley and the wheel is where the belts go. The crankshaft of the engine turns the wheel and that turns the belt. Without this component there would be no torque or speed. Other car systems are linked directly to this pulley as well. The alternator which charges the battery would not work without it. Neither would the steering pump or the air conditioning system. The accessory belt idler pulley is under significant stress during car operation and will wear down or break over time. Replacing this pulley as recommended saves drivers costly repairs.

This is a preliminary review. I have received the belt kit but as yet it is not installed. PartsGeek had the best pricing and the delivery was fast. The parts are genuine Gates brand and not some knock-off brand from the far East.

I'll update once I see how these parts fit my sons 2004 525i. - Good quality parts and decent price
