Product Details

This serpentine belt drive component kit is intended to restore the front-end accessory drive as a system. Replacing the belt, tensioner, and idler pulley together helps address uneven belt wear, tension loss, pulley noise, and related accessory drive concerns that can appear when only one worn component is replaced. Gates 90K-38153 is a practical service choice for Buick Lucerne and Cadillac DTS models listed in the fitment data, including 2006-2011 Buick Lucerne, Accessory Drive and 2006-2011 Cadillac DTS, Accessory Drive.

This part cross-references Monroe Shocks & Struts (e.g., DBK060832A) for the same application.

What It Helps Address

• Squealing or chirping from the serpentine drive
• Visible belt wear, cracking, or glazing
• Weak or inconsistent belt tension
• Idler pulley roughness or noise
• Accessory drive service after belt-related maintenance

Installation Notes and Tips

Verify the vehicle’s accessory drive configuration against the notes, including the 2007-2008 Cadillac DTS without heavy-duty cooling note.
