Dayco Accessory Drive Belt Idler Pulley P/N:89823
Dayco 89544 accessory drive belt idler pulley for the 2001-2006 Mitsubishi Montero guides the serpentine belt along its path around the engine. As an idler, the Dayco accessory drive belt idler pulley does not drive an accessory.
A squeal, a grinding or rumbling noise from the belt area, or uneven belt wear can mean the pulley bearing is wearing out. These signs alone do not prove this pulley is the problem, since a worn or loose belt can make similar noise.
It fits the 2001-2006 Mitsubishi Montero, including the 2004-2005 Montero V6-3.8L. This listing is one pulley, and the 2001-2006 Mitsubishi Montero takes one.

Is the Dayco 89544 idler pulley right for the 2001-2006 Mitsubishi Montero?

What are the bearing dimensions on this idler pulley?
This idler pulley has one bearing with a 10.3 mm inner diameter and a 20 mm width.
How can I tell if this grooved idler pulley is worn?
With the engine off and cool, look for side-to-side play, a rough feel when turned or a worn groove surface. Squealing or grinding from the belt area while driving can also come from the bearing.

No. Dayco 89544 is a grooved idler pulley with one bearing; it guides the serpentine belt rather than driving an accessory.
