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 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

GM tensioners are spring loaded to provide the correct tension on the serpentine belt. If the belt is loose, either the tensioner is bad or you're using the wrong belt.

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

Depends on the engine. 4 Cylinder GM engines used a pair of timing gears (no belt), while the V-6 used a gear and chain system. Neither one used a belt (other than the serpentine belt to drive the AC, alternator, power steering and water pumps.

the 4.3 has a chain, luckily gm was smart enough not to put a belt in them.

need picture of belt for 99 Sunfire Ah yes, the infamous serpentine belt! It's among the most asked about items in the Sunfire group. My car still has a diagram for belt routing on the underside of the hood. Yours might too. If not, and the belt is still on the car, make a quick diagram of your own for reference. If your belt has left the car and has joined the bits of semi truck tires on the highway and you can't find a diagram, you're not screwed, but it sucks. Most any GM dealer ship should be able to come up with a diagram for you.

generally you back up the spring loaded tensioner enough to remove the belt --then just put on a new belt but and there is a big but there are several GM 3.8 engines ---one of which requires the removal of the front motor mount which means the engine has to be supported while you are changing the belt---be aware there is always a diagram of the belt routing under the hood someware

Most Jimmys use a spring loaded belt tensioner that is not adjustable. NOTE: It is normal for belt tensioner to "bounce" a little bit when engine is running. If your belt is squeaking here are a couple things you can do. Replace the belt with a QUALITY belt. Don't buy the cheap belts on vehicles with long serpentine belts. They will squeak. I recommend Garorback belts. If your belt is still squeaking ensure that all pulleys and belt driven items are working properly by rotating and checking them with the belt off. Most GM vehicles have an idler pulley. It is very common for the bearing on it to go bad. If you still have a squeak then replace the tensioner assembly. They are readilly availably at parts stores.

Remove serpentine belt and have new tensioner ready, look at it the bolt holding it to the block may be lefthanded thread usually 18 mm. Mosy gm parts are bolted on with metric so try to take it off with left handed thread (clockwise first) if that isn't it then do the normal way put belt back on. A belt tensioner tool is a good investment. they ar eat autozone and cheap and make the job a 5 minute task

Go to your local parts store and buy a chilton's manual or if you have friendly people at your local GM dealership garage, ask them to make a copy for you :O)

The 4.3L V6 GM engine does not have a timing belt it has a chain, and it does not directly drive the distributor.

Looking at the engine from the front of the car, the water pump is on the left side. It is the front most & highest pulley being turned by the serpentine belt. Right in front of the power steering pump.

Depends on the condition. GM trucks do seems to crack sooner than most. IF cracks are present every 1/4" perpendicular to the grooves, pieces are missing, there are any cracks going the with the grooves, fraying on the edges is occuring. oil is present on the belt, then replace it. Otherwise, probably not. If it makes noise then that may case you to want to change it.

to change the belt ....there sould be a diagram of running route ...under the hood....you will have to drop the starter....no special tool ....flat heat screwdriver....socket to drop starter. GOOD LUCK, LISA No, you do NOT need to remove the starter! Are you kidding? That's like the GM Vega, having to pull the engine to remove spark plugs! Starter has nothing to do with the belts. You need a belt tensioner tool (up to 1990) to release the tension of the belt. Put new one on using the same routing of the old belt. Release tension off tensioner, and good to go. If you have the belt off, it is a good idea to also replace water pump belt, since it runs behind it. (up to about 1991... '92 and later use serpentine for water pump as well) Keep in mind, Tempo up to 1990 uses a different tool for the tensioner. 1991 and later, you can just use a 1/2 inch ratchet drive.

does a v6 gmc onvoye have timming belt or chain

Divide (gm) by 1,000 to get the same mass in (kg).
