Product Details

The Genuine BMW Drive Belt Idler Pulley (part number 11-28-7-841-531) is a factory original equipment component designed to maintain proper tension and alignment of the accessory drive belt system. This idler pulley ensures smooth operation of critical engine accessories including the alternator, power steering pump, air conditioning compressor, and water pump by providing a precise contact point for the serpentine belt.

Key Features:

  • Genuine BMW OEM part manufactured to exact factory specifications
  • Precision-engineered bearing assembly for smooth, quiet operation
  • Durable construction designed to withstand engine heat and vibration
  • Maintains proper belt tension to prevent slippage and premature wear
  • Direct replacement for worn or failed original pulley
  • Includes sealed bearing for maintenance-free operation

Over time, idler pulleys can develop worn bearings that cause squealing noises, rough operation, or complete failure. Replacing a failing idler pulley with this genuine BMW component restores proper drive belt function and prevents potential belt failure that could leave you stranded or cause engine damage from loss of cooling or charging system operation.

Not only was our item cheaper, it arrived quickly. Will def. purchase from Autoplicity again! Thanks!

I was very happy with how simple the ordering process was and the price was the lowest around fro the part I ordered. John

Quick and direct to my part

I ordered a new clutch on June 12, and the item shipped the same day. Had the item on time as expected. They also beat all other retailers prices by a significant amount. Their shipping costs were also reasonable. The only issue I experienced is that it is virtually impossible to get order status from their Website if you do not have an account. Anytime I used the link provided in the order confirmation E-Mail would always return an error.

Good Experince

Found the K&N filter for my 2012 Acura TL at Autoplicity for the best price and delivery took about 2 business days. Can't ask for more.

Excellent place to shop for you aftermarket needs. Very low prices and really fast process/shipping.

great

Best prices on every item I have purchased. Shipping is quick and items are factory fresh and as described. Great place to shop...always check their store first!

Quick to ship. No complaints here.<br>

This is a great site

Very fast shipping. Excellent item detail and description available before purchase. Best price on the net!

this was my first time shopping at Autoplicity and it kind of made me nervous not really knowing anything about their site but i recieved an order confirmation immediatley after ordering and it was shipped extremely fast.
