DIY: Serpentine Belt and Tensioner Pulley Replacement.

Will give a how to, and pictures when I'm finished.

good, thats my next project...was going to do a DIY but i took off the air injection pipe and couldnt get the belt out, so im guessing most of the front end and intake will need to come out...if you find an easier way let me know and post plenty of pics. ill hold off on starting till then

I know exactly where you ran in to problems, I'm going to include the factory write up than my own experience. Make sure you get the right belt. I got a 3.0L GM belt for supposedly our car and the Saab. Yeah, 1 1/4" makes all the difference in the world. Didn't fit, took the old one to the shop and got the right one. Install than took 5 min, by myself.

Here it is from the service manual. Some of the info is handy, but I found it easier to access from the top for some things.


The book says about $70 for the belt and 7/10ths of one hour for a professional mechanic, so figure 3X that for the DIY person. Not too bad as long as you don't have a bad back.

Again, some of the steps are not nessecary, and I did not need them. Will post pics of what I needed to get around.

yea the air injection pipe was the problem i had...did you have to remove the whole pipe? i tried just removing the bolts and hose clamps but somehow the belt kept getting hung up around the a/c compressor...i notice the tech pub doesnt mention anything about that so im guess the a/c doesnt need to be touched? i tell you what though for the 70 bucks i paid for the stupid book, i think its worthless, pictures are terrible and the instructions aren't descriptive enough.

another thing...did it seem like with a little more effort youd have access to the timing belt? i mean if its there might as well kill two birds with one stone

Well, to get at the timing belt, most of your pulleys need to come out, as well as some brackets I think. Haven't done timing belt, so not entirely sure what the process is.

ok, ill figure it out when im in there...any pics yet?

sorry haven't had time to load them up. Hopefully tomorrow.

no pics?
