What size wrench should I use on the tensioner?

[Milkman00]

I have a friend that wants to replace the serpentine belt on a 98 SW2.

The location of the tensioner makes it almost impossible to reach with a standard length wrench. I want to buy a real long wrench to move the tensioner (assuming I just have to move the tensioner with the wrench to loosen the belt). I just don't know what size wrench I should buy??

Can anyone tell me if this is the right method, and what size wrench I should buy??

OEM 14mm. Many aftermarkets are 15mm. You can tie a piece of clothesline cord to the end of any combination wrench to get the leverage you need to wind up the tensioner from above.

Can you not slip a piece of pipe over the end of the wrench?

I found it easier to remove the rt frnt tire, splash-guards and get to the tensioner from below (using standard length wrench). Guess I am not coordinated enough to get to it from above

I use my left hand to rotate the tensioner and right hand to lift it off the AC pulley

The Richpin method..

Although I'm a little hesitant to recommend HF.. it's on sale, and you can use the 20% off coupon from the Sunday paper so it's ~$14 + the freebie of the week. Works well to wedge between WP pulley bolts as well.

I think this method is easier as well. Even using the stock jack and lug wrench the time removing the wheel is saved in less time playing games with the belt routing and trying to stick my hand in a place too small for it.

I've done it both ways, but removing the wheel seems much easier to me.

I had my serpentine belt off just yesterday. A standard 14mm box end wrench works. Access it through the right hand wheel well as alordofchaos said.

Remove the wheel and front access panel. Feel up and to the left of the harmonic balancer. Using the wrench remove the tension (rotate the tensioner pulley bolt clockwise) and slip the belt off the balancer first (personally I find it easier than reaching the A/C pulley, but that will work too ).

Takes about 10 minutes. Very easy to do. Be sure to use a jack stand of course.

Sorry it has been so long since I replied. My friend hasn't brought his car back over yet, but thanks for all of the great information!!!
