Product Details

Gates DriveAlign Premium OE Pulley line focuses on direct-fit replacement pulleys for accessory drive belt systems. Part number 38069 is a smooth idler pulley with no grooves and no flange, matching applications that run on the backside of the belt. This design supports proper belt tracking in BMW alternator, water pump, power steering, and air conditioning positions where OE-style pulley geometry matters.

This part cross-references Continental 49062 and Dayco 89089 for the same application.

What It Helps Address

• Belt noise from a worn idler pulley
• Uneven belt tracking on the accessory drive system
• Visible pulley wear or surface damage
• Accessory drive belt vibration
• Service replacement for BMW belt routing components

Installation Notes

Verify pulley diameter, bore size, and contact surface before installation. Confirm the vehicle position listed in the fitment data, especially on BMW applications using alternator, water pump, power steering, or air conditioning routing. Inspect the belt and adjacent pulleys during service so the new pulley operates on a clean, aligned drive path.
