The tensioner pulley is spring loaded and can be moved to release tension on the belt. There is usually a square hole in the pulley bracket that will accept a 3/8" ratchet or extension.

How do i remove a serpentine belt?

You need to loosen the tension of the belt first. Once it has been loosened enough, the belt should simply come off. If any other parts need to be moved to get it out once it is loosened enough, simply move/remove them and reinstall them correctly once you are done.

Where is belt tensioner and how do you turn it to loosen belt to change

The belt tentioner pully is the idler pully in the serpentine belt system...
You need a long wrnch (11/16??) to fit the pullys center bolt...
Turn the bolt to the right ( righty tighty) and the tentioner will losten its tention on the belt enough to remove the belt...
Imediately replace the belt ... so its routing is not forgotten by time or distraction...
If there is still a sticker on the upper radiator support reflecting the serpintine belt routing.. then you are in a better spot to be doing this ... with distractions...

Need to know how to adjust serpentine belt, please show diagram. 6 cyl engine.

Really don't need a diagram. Loosen the slide bolts on the power steering pump. loosen or tighten the pump by turning the jack screw (long transverse bolt) under the pump. Once the belt is tightened up, lock down the slide bolts and you are finished.

How do I release the belt tension pully to replace serpentine belt

You can run down to your local auto parts store and buy a serp belt tool. Or you can take a 3/8 drive ratchet, locate the 3/8 square hole in your tensioner and put the ratchet in the hole. For more leverage I put a deep socket over the ratchet handle and put a long 3/8 extention in the deep socket. This will provide ample leverage and will save buying more tools you do not need. Simply move the tensioner to the direction that takes pressure off of the belt.

You gotta move the idler pully with a wrench and the belt will loosen enough to come off. The trick is that you have to have one hand on the wrench holding the pully down while you r & r the belt. My wife held it for me when I did mine

How to put on the serpentine belt for a 1994 plymouth grand

Well, first of all you don't "loosen" the tensioner. Tighten that back up. Route the belt as it should go. Put a 15mm open-end or box end wrench on tensioner bolt (in the middle of tensioner.) To make this really easy, I use a "cheater" (a pipe large enough in diameter to go over wrench) to give added leverage to pull down tensioner far enough to slide belt over. Personally, I route the belt over everything except the idler pulley then pull down on the tensioner far enough to slip the belt on the idler. Because of the small cleareance, trying to use a socket on this bolt is almost impossible however, the previous is the method I've learned to be the most efficient.

Changing Serpentine Belt on '01 Impala LS (3.8L)

Can u turn the nut in the opposite direction that u have been trying? U need a lot of leverage to get enough tension off to remove the belt. If u have enough room, add a pipe to the end of your wrench, u will need a lot of room to move the tensioner enough. U might have better luck buying the wrench made for that purpose at a parts store. I think I paid about 25 a couple years ago, I couldn't fit a regular socket and wrench on the tensioner, it was a very tight space.
