At an idle my timing belt "clatters". It's hitting the top of the cover, when I remove the cover I can see the belt moving up and down with the engine running. The belt is due to be changed (100k miles) but it looks to be in good shape. Could this be a loose tensioner problem? I've also had a trouble light come on and when read it says the engine has been running too lean. Could this be related to the timing belt? It's a '97 with a 2.0 4 cylinder.

My '96 Mystique had exactly the same condition when I bought it. Turned out that two of the tensioner pulleys needed to be replaced as well as the belt. I think it was the pulleys, rather than the belt, that were causing this problem.

Before I got rid of my previous car, a 1994 Tempo, I swapped radios. I liked the Tempo's radio better. That counts as a mod, doesn't it? I also kept one of my Tempo's wheels to use as a spare. I hate those stupid ?compact? spares that come with modern cars. Does this count as a mod? If so, I guess I have two mods. Replaced burned/melted blower switch and connector on 19 February 2002 with a 1P3T toggle switch from Marvac and a Molex connector from Rat Shack; I guess this now makes three mods.)

My 97 Zetec had the same problem. It's the belt cover being hit by the belt. You can either bring it to your local dealer and they'll put spacers on the bolts to give it more height or replace the cover all together. You could also do this yourself with some thick plastic/nylon washers. The dealer charged me around $60 to do this so if I could do it again, I'd fix the damn thing myself. Oh well, hindsight is 20/20!

I have a 99 Mystique with the Zetec. I had a rubbing scraping sound with only 29k miles. I pulled the top cover and found the belt to be ridding right on the edge of the pulleys and to be chewed up. Ford fixed it under warrenty. They replaced the tensioner. ....Brad

You need to be careful.. The Zetec is an interference motor and if that belt snaps you could have alot more issues on your hands than just replacing the belt... Just lookin out for ya... Mine was making that same noise and when I took the car apart the belt was shot and ready to fail.. My car had 90000 miles on it and Ford recommends replacement around 75000 miles if I'm not mistaken. It is a pain in the A$$ if you want to do it yourself.... I had alot of fun doin it.

hey bro, your timing belt clatter, well id say replace the timing belt. close tolerances equals bad deal. your valves will go right through your pistons if your belt goes. by the way, ive replaced my timing belt at 120,000 miles only. longer than i should have gone but nontheless its changed now. CHANGE IT

oh one more thing, your tensioner pully will have a spring on it. not to mention a screw-in stud on the engine block. my stud loosened and fell out itself, and my spring wound up gone. make sure your stud and spring are still there. and a hacksaw blade makes a perfect alignment tool for your cams.
