New Drive Belt Burning Hot

[LarryJohnson]

Installed a new oem drive belt today and notice it smelled during initial test drive. Extemely hot to the touch. When replacing I noticed one of the belt guides was worn. This belt is much thicker than old after-market belt. Guides aren't bent. I rotated the worn guide , but still belt gets hot. Normal?

The belt is wrong or has been routed wrong or one of the idlers has seized
Guides always go to the outside of the belt,

No not normal.

Is this an OEM belt or after market? I have seen where an after market supplier will try to use a 1/2 in place of a 7/16 belt. I have this to happpen on a CC I was replacing the drive belt on.

Also we need the equipment numbers and the belt PN used.

The belt is spec. Guides are on the outside. Idlers spin fast enought to whistle while compressed air is blown over them.
Belt S's through the idler. Had to really squeeze the belt between idler pulleys.

Check your routing and pulleys.

If you can make the pulleys whistle when you blow air on them, I would say the bearings are worn. A good bearing should not make noise. That and a slightly short belt will heat up quickly.

Double check the routing at the steering wheel shaft.
