GV 3.3 Tensioner replacement

[Paul94Z28]

Hello-

I did a search on tensioner replacement. Good hints, but it seemed like the engines discuused were different from mine.

My tensioner is frozen and is is making the squealing sound that other have comlained about. My tensioner is right in the middle of the other pulleys. It is frozen so bad that I can't even get the belt off. Before I slice away I want to make I can get it back together.

The tensioner I have has only 1 bolt to hold it on. I have no idea how to get to the nut on the other side that anchors it.

Any ideas?

Paul

if memory serves me right its a 15 millimeter nut and i use 1 15 milli racheting wrench behind and under the alternator

Faulty-

So from underneath, get a racheting wrench on the back of the tensioner? It did not look like to much room. Socket wrench or ratcheting crescent?

I would try using a gear wrench (ratcheting wrench). They are low profile and work really well in tight spots. I also would suggest taking your front right wheel off and the wheel well covers to get a better angle on it.

I assume you are using a special tensioner wrench, which is at least 24-inches long to move the tensioner. If you are only using a standard length open-end or box-end wrench, it won't move and will appear frozen. With the proper wrench, you will need to attach to the pulley center bolt and rotate the unit clockwise to loosen. If that doesn't work, turn the same bolt counter-clockwise to loosen the bolt and remove the pulley from the tensioner assembly (yes, the pulleys are removable). This should give you clear access to the tensioner attaching bolts.

If you are hearing a squealing noise when the car is running, chances are the bearings in either the tensioner pulley or the idler pulley are worn and need replacement. These pulleys are interchangable. You can buy replacement bearing and press them in yourself, or buy replacment pulleys with new bearings installed.

Good luck and happy wrenching.

Gotta love that blind bolt. Up from the bottom and in under the exhaust manifold we go. I got it in, and rented the special wrench to get the belt on. Car sqeals about 1/2 as much, looks like the idler has to get replaced also.

Thanks for the assistance!
