Hello,

In the diagrams down below I have included the diagram of your vehicle's drive belt as well as the instructions for the removal and installation of it as well. I have also included the Original Equipment Manufacturer[OEM] parts number for the drive belt as well. Please go through these guides and get back to us with how everything turns out.

Thanks,

You need to get it all lined up and ready to slip onto your last pulley, some tensioners (GM) usually have a 1/2 square hole in the tensioner arm to put a 1/2 drive ratchett into, some dont, if it does, use the ratchet and apply force to the tensioner test it by pushing both ways, it will move to loosen only as tension is always applied, push to release the tension as you slip the belt on, if no square hole, use a box end wrench and apply the force on the hex head in the middle of the pulley. I use two wrenches together to get more leverage.
Slip the opened end of the wrench that fits on the tensioner into the box end of the extra wrench.

Hello,

The tweeting is more than likely 1 of 2 pulley's. There is an Idler Pulley and a Tensioner Pully. To figure out which one it is. With the vehicle off find the 2 pulleys, spray the center bolt on One of them with WD40 or Similar. Start the vehicle if the tweet goes away then replace that pulley. If is didn't go away turn vehicle off and spray the other pully the same way and restart. If tweet is gone then replace that pulley.

Ok the I guess Dent ( ). Depending where exactly the dent is. If it is a good size dent and is on the hood (flat surface) you can probably just take a plunger and pull it out. If it is on the corner or curved area then that is a little harder to do and may require drilling a couple holes to pull the dent out.

The belt tensioner has a square hole that a 3/8 ratchet or ratchet extention will fit into. Just turn the tensioner counter clockwise to loosen tension on the belt.
