There should be a tensioning pulley that you lift off of the belt to create slack in the belt to get the belt off. Make sure you have a diagram of the belts routing before you take it off so you know how the new belt goes on. Take a picture or draw quick sketch.
Go to a GM dealer's parts department or service department. They would know.
To which vehicle does GM Part Nr 10085752 belong? Any small-block V8 Chevrolet. It is a drive belt and part of the Serpentine Accessory Belt Drive System (Part Nr 12497698. This deluxe serpentine belt drive system with air conditioner includes all the components to install on small-block Chevrolet engines. See the link below.
It's on a sticker where the shock absorber is. If it's missing, a GM dealer's service center will have it.
There might be a picture of this under the hood. Alot of GM's have this. It is possible that the engine mount will have to be removed for this depending on what engine you have .
There is a special tool for that. Try a GM dealer's service center. They should know which one it is.
There is no set mileage to replace the belt. Inspect it for cracks and or frays. If you see cracks or it is frayed or worn then replace it. Also if it becomes stretched to the point it slips, replace it.
Most auto-parts stores can and will provide this as a print-out (may be a minimal cost) when you purchase parts from them.
yes, i have the same car and my air conditioner burned out years ago. instead of replacing the air conditioner i just got a new belt - GM makes a belt specifically for this
If the diagram is not still on your radiator shroud or the underneath side of your hood, your GM dealer has the stickers or fiche to show the routing.
I found the serpentine routing chart for my 87 Lincoln lsc in a Mitchell's auto repair book at the local public library. There are diagrams for many autos. You can xerox the book and take home a hard copy for $0.15
