Replace belt tensioner 2004 pontiac grand am v6 engine

SOURCE: belt tensioner

It is a very involved process of removing and replacing. You will have to remove all of the belts, the front timing belt covers, (upper and lower). You will also have to remove the front bracket that is mounted to the front of the block, which serves as the mount for the power steering pump, the alternator and the A/C compressor.You will also have to remove the crankshaft pulley. You cannot remove the plastic lower timing belt cover unless you remove all of these things first. The tensioner is located underneath the lower cover along side the timing belt on the passenger side. It has two bolts that hold it in place. You will have to remove these two bolts.

The crankshaft pulling bolt is a right handed thread and loosens by turning counter clockwise. The pulley will slip off but is a very tight fit. Do not try to turn it while removing it as there is a small pin that keeps it aligned to one position. Use a small ball pine hammer to tap it loose.

It is also a good idea to remove the electric cooling fan shroud that is mounted to the inside side of the radiator and the radiator hoses to give yourself more room to work. It has only two bolts at the top holding it in place. And then slips into two retaining clips at the bottom. Lifting it will pull it out of these retaining clips.

When you remove the small bypass hose located at the top of the radiator , to the passenger side, be careful not to break off the small nipple protruding out of the radiator tank. It is plastic and will break easily if you try to pull the rubber bypass hose from it. This will have to be taken to a radiator shop to have repaired if you accidentally break this off. Be sure to carefully loosen the hose from this nipple before trying to pull it off.

And one more thing, if you go to that much trouble to replace the tensioner, it is a good idea to go ahead and replace the timing belt as well. It is a maintenance item and you will have to go through the same process to replace it as well. Do it once and do it right.

I hope this helps.

Hello,
Basically, Remove the belt. Then remove the bolt that the tensioner pivots on and remove it. It's fairly easy.You may need to remove the belt pulley to make it easier.
The problem comes as your trying to get to it. If you can't see it well or something is in the way. Like the plastic overflow tank or something like that. Then you will need to remove what is keeping you from getting to the tensioner. I did one on a four cylinder last week. The belt pulley on that one had a left hand thread. The tensioner itself should be right hand thread.
Good luck.

1. Lift the car so you can work from underneath when needed.
2. Disconnect the battery . Just to be safe.
3. Take the serpentine belt off.
4. Remove the alternator.
5. Remove the A/C compressor. (You can do it without removing, but it's a royal PITA... LOL) Don't unhook the lines, just unbolt and move out of the way.
6. Remove the worn tensioner from t he block. (You need to unbolt the pulley first to get to all the tensioner bolts)

SOURCE: I need a diagram for a surpentine belt on a 2004

The label that has the diagram is located either under the hood with the engine emissions info sticker, or on the front crossmember of the engine bay. If the sticker is missing, this page has all the diagrams to every serpentine belt they sell. The link to the diagram will be on the left; look for it because it doesn't appear as a link.

Hope this helps,
