My timing belt is loose and I want to tighten it myself, I just got it back from the shop that cleaned out my head so they did a timing job so everything is new, guess possibly they didn't tighten everything up right but I don't want to take it back to them cause I've heard they had a bad Rep if things didn't come out right. I know you need the timing belt tool is there a certain way I have to do it? And I believe my idler and Tensioner pulleys are loose as well. How do I act upon those? Here's a video of the noises they make and at 4:25 you'll see how loose the timing belt is

Actually you dont need a tensioner tool, you can use a bolt about 5 inches long. Been a while since I did mine but Im about to do it again this weekend since im changing my rings. Basically you just thread the bolt through until It makes contact with the tensioner arm, thus pushing the pin of the tensioner back inside the tensioner body.

After youve set he pin you tighten the belt pulley by hand (no torque tool required either)

The critical part of doing this job is to have the correct gap between the tensioner arm and the top of the tensioner body. I used a drill bit to check the gap thickness. I dont have my shop manual in front of me but If i remember right it was like 5/64.

As long as the gap here is correct after you back out your 5 inch bolt your belt will have the correct tension. I can give you more info if you need but thats basically it
 
That kind of hum at 4:25 sounds like it could be your timing belt tensioner (sp?). Those should be replaced with the timing belt as their good for about 60k.

But on a more serious note!!! If they let you take your car home sounding like that then you need to go back to that shop and start knocking some heads! LOL

There are plenty of Vfaqs, tech articles and videos on this process.
Just out of curiosity, have you viewed any of them?

I was clueless when I started my timing job but now I'm fairly proficient. The resources we already have available to use were extremely helpful.

Yeah if you don't mind, id appreciate it. I just needa to tighten up my timing belt and it should be good to go. And it wasn't making that noise right after the shop, it was after I took it down the track it started making that noise.
