I need the routing diagrams for a 2003 Regal GS serpintine belts.

Hi there, Belt information. Mark (mhpautos)

Thanks! I removed it thinking that there was a diagram on the car...

The serpentine belt is worn and needs replacing. Does it have a special tensioner that requires specific tools or is it adjustable at the alternator.
Also do you have a diagram of how it fits around
all the components. Are there other suggestions that would be helpful such as removing a splash cover from beneath the car.

Look at you VIN. Match the 8th digit with the diagram. They all use a tensioner. Splash removal is not necessary. The belt is removed from the top of the engine. VIN "1"

VIN "K"

VIN "L"

1998 Buick Regal mileage: 65,000. I am getting ready to replace the serpentine belt and need to know if replacing the automatic tensioner is advised. The belt is not that bad, but i thought it was about time. Thank you!

Yes, it is a good idea to replace the belt tensioner when you replace the belt. Over time, the spring inside gets weak and looses tension.

serpentine belt jumps off pulleys.

You have one of three problems. One of the accessories the belt drives is out of alignment. One of them has failing bearings causing pulley wobble. Or more likely is that you have a bad belt tensioner assembly.
