Timing Belt replacement

I'm attempting to replace the timing belt on a 2001 Focus with a DOHC 2.0.
When we got the crank and # 1 piston at TDC on the compression stroke, the cam on the intake side is horizontal on the back side where you're supposed to use that alignment tool, but the exhaust cam is off quite a bit it looks to me like. What should we do to align both cams if that is what is what needs done?
Maybe this is why the car wouldn't run at an idle before when we baught it.

Before doing anything, twist the crank 1 turn to see what the opposite stoke looks like, then back to where you were if it's off there (just to check for the right stroke).

Cam gears get loosened to set the cams perfectly - you'll see that when you read the entire procedure. Hold the cam with a wrench to loosen/tighten sprockets - bar to check alignment. Bar to hold often ends up with broken cam ears....

Step by step & think it through for this one, helps to get it right the first time!

And crank it a couple turns to test when done by hand, easiest time to check your work.

Luck!

The slots need to be horizontal and slightly HIGH. Tool will not fit if they are horizontal and LOW. It's a check for correct stroke, the slots are cut slightly off center. Yes, both slots must be the same, or you definitely have a problem there. Change by loosening sprocket bolt and moving cam to suit.

Is there a link to a site that shows the proper procedure?

we recently baught this car, and one of the previous owners had installed focus central pulleys. Would this have anything to do with the cams dont line up the same?

Serpentine pulleys wont have any affect on cam timing. All you need to do is make sure piston #1 is at TDC using the timing pin, grab a T-55 torx and loosen the cam gear bolts, line up the cams so the timing bar fits in the end, and tighten the cam gear bolts back down.

Here's a "how to" thread on Zetec timing belt replacement. Very detailed, with a lot of posts asking questions that might match ones you come up with...

Luck!

the pulleys wont make any difference. Your problem is not a problem. If you are replacing the belt put the #1 piston at TDC after removing the belt. This is all you will have to do for the crank. Now turn the cams until the locking tool for them can be inserted into the ends. These are the main two things to do for the timing.

Also, since this appears to be your first time doing anything like this, if you loosen the cam gears then DO NOT TIGHTEN THEM WHILE THE CAM LOCKING TOOL/BAR IS STILL ATTACHED OR YOU WILL BREAK THE SLOTS ON THE CAMS. I just have to emphasize this since this happens often

Smikes there's plenty of examples of actual timing a Zetec on YouTube. Once you see it in action you should understand better what the guys are saying above.
