millinia timing belt ?

[383stroker]

i have an 01 millinia with the 2.5 and it just started making a knocking type sound that would come and go. it sounds like it is coming from the timing cover, so i pulled some of the top bolts that hold the plastic front cover on and shut the engine off. when i pulled the cover back so i could see the belt, it had alot of slack in it between the rear cam and the front cam. my question is, should i have this slack and could this be the source of the noise?

"Hard" is a relative term. I don't personally think there is anything hard to it but if you've never done a timing belt job on any vehicle before then I could see how it is a hard job.

There are some tips and tricks scattered throughout the net and on here to make the job go smoothly.

ok i got the tensioner off and i am able to push it up against a wall and put the pin in it, should it be this easy or is it definitly weak? or how can i test the pressure?

You would not be able to push the tensioner in by hand. That one is def. blown.

Is the S a non-interference timing belt ? Because I had always thought that till one of my mechanics told me otherwise.

They will at about ~$150 a pop. Cheaper to just buy the entire assembly used. I had some custom jackscrews made and they will custom make anything and everything you want. The OEM tensioner has both left and right hand screw treads so it's a pretty unique piece. I stock up on rare parts like this and I am certain I had an extra one. Let me check and get back to you.
