So my GF has a 2001 ford zx2 with a 2.0 zetec. Its got about 100K miles on it and it died about a week ago going down the highway, the timing belt was halfway snapped and must have jumped out of place (the computer registerd a camshaft rotation error). Well for the past week I’ve been trying to replace it, but it is so hard to find good info anywhere, the haynes manual sucks, Zx2fast had a tutorial on here that was good though, but still left unanswered questions.
I actually did just finish replacing it, however the car is running horrible. Its shaky and choppy. It actually sounds about the same as a car with a bad spark plug, that sort of helicoptor sound, and shaking on acceleration. (perhaps it could be a spark plug, I haven’t replaced them yet).
As far as I know I did it perfect. I used a perfectly fitting piece of metal to align the cams, and had the crank at TDC on piston 1, tension seems great, all lined up. I also hand cranked the motor a full rotation back to tdc to make sure everything was still lined up. It was very close, the cam closest to the front was just slightly off, by maybe about 4 or 5 degrees, but from what I understand that’s normal
Is it possible that having the timing belt on wrong (perhaps even by one notch) could be doing that?
Also heres my other questions I couldn’t find the answer to anywhere.
2. What’s the deal with the camshaft closest to the front of the car, its like spring loaded or something, was I perhaps supposed to wind up the spring a little or something?
3. Even though I had the cams perfectly aligned, the teeth didn’t mesh perfectly on the second cam, the teeth on the belt were sitting on the teeth of the cam. (as if its 1/2 a tooth too short/long). When I pulled the belt on tight the spring tension rotated it and took up the slack, but is that normal?
4. Does the zx2 have a place to check timing, so I can check if I’ve got the timing belt on correctly?
Thanks
