Not really -- the tensioner is held rigid in operation, the spring is only used while setting the tension. This is why the car ships with no spring in it and you have to buy the spring later.

Thanks, Paul! I am starting to figure out where the rattle is coming from. Before your post, I thought the slight side-to-side movement in my tensioner pully was normal, i.e. just the "tensioner spring" taking up a little slack. But as you said, the tensioner pully should not be moving back and forth. So maybe that's where the rattling is coming from. I'm taking it to a mechanic tomorrow.

None of my business, but I hope they're nice enough to have purchased the proper tools for that engine...crankshaft timing peg [installs near PCV valve]...camshaft timing tool [flat bar]...and a good cam sprocket holding/removing tool.

Good info. I'll ask them if they have those tools, before I leave the car with them.

If it's a pretty good shop that employees a few certified mechanics/maniacs  that aren't afraid to fill up their fancy boxes with actual tools, they shouldn't get offended for you asking...if it does offend them, not a good sign, imo.
btw, there are 2 styles of tensioners, I think. One that requires a spring and new bolt [dealer items...Part Nos. W700001-S309/6L277] or the newer design that is pretty neat...no spring, just rotate till the marks line up.
Good luck.

Thanks for the part number. I'll look into that new design. It would be nice to get one that lasted longer than the first one (27,000 miles! Grrr.)

A timing peg (whatever that is) and a cam sprocket tool are not necessary. And any mechanic will have a file that will fit to hold the cams. Most mechanics will not have a problem doing a simple timing belt change on a zetec. In fact, I'm sure most have done them before. I even found a shop (the only shop) that had no trouble installing my cam gears and actually doing it in less time than they thought it would take.

91 Escort GT (almost sold)
96 ATX Zetec (i brake to watch you swerve)
FS: SVT rear sway bar
WTB: Very cheap beater

Kremit, how would they re-set the timing w/o the cam sprocket tool? When they take out the old tensioner, the belt will go slack. Won't that throw off the timing?

The later models have the new design, they really can't be altered.

You don't know about the tool that fits right in the access hole in the block that Ford designed for the tool that they designed to hold the crank? Tells me all I need to know.
Cam spocket tool isn't necessary, even on the newer ones? Really?
File? LOL
Doing them, or doing them right?
You found a shop? Why? Not doing the job yourself, expert?
