Jetta Timing Belt

[frankev]

Hey all you timing belt experts, need your help!

99 Jetta GL 2.0L with AEG engine

Belt broke and had to have the exhaust valves replaced and then installed head back on ok with no problems.

There is a notch on the crankshaft pulley and I lined it up with the mark on the lower timing belt cover for piston TDC. I then lined up the notch on the camshaft pulley with the OT mark on the bracket on top of the valve cover. I made sure the piston was on the compression stroke by noting that the intake valve had just closed prior to the notch on the camshaft pulley lining up with the mark on the bracket.

Carefully put belt on without moving either pulley and set tensioner properly. I have turned the crankshaft about 30 or 40 times now due mostly to paranoia and wanting to make sure everything is ok and the marks still line up properly - both crankshaft and camshaft pulley notches still line up with respective marks together. I would think if something were amiss the marks would be off but they are still dead-on after all those rotations. I really want my poor old valves to stay the way they are - not bent - for a long time.

Did I get it right?

Do you have a manual transmission? If so, pull the flywheel sight plug, there is a notch on the flywheel that lines up with the notch on the tranny. Sounds like you did everything right.

Its an automatic.

I read where you can check the mark on the torque converter for TDC but I had trouble finding it and then found the notch on the crankshaft pulley, which is much easier to view.

The link you attached is a great link for changing the waterpump and timing belt (I did use it and thanks for sending it!) but in the instructions he uses the marking method for replacing the timing belt, which assumes your belt didn't break, unlike mine. He also says to use the Bently manual if you don't use the marking method although I don't have that manual. I do have the Haynes manual, which I feel is pretty well written for my car although this is the first time using the manual to replace the belt and I so don't want to get it wrong!

Have also been curious to see if anyone has counted the number of teeth on the belt between the notch on the camshaft when at TDC and the notch on the crankshaft when at TDC also. This would really verify work when replacing the belt if one knew the number of teeth that seperated the notches. The only catch is that since the notch on the crankshaft pulley is at the 12 o'clock position when at TDC, you would have to add half the teeth on the crankshaft cog to get the 6 o'clock position since the belt wraps around the bottom side of the cog as opposed to the topside of the cog. Am I making sense?

Sounds like you got it right. If you don't feel any interference after turning the crankshaft two full revolutions then you shoud be ok.

The guy who did this Audi TT TB counted 68 teeth between marks but I wouldn't rely on using that as a fitting guide. Never mind - I just realized you have a 2.0 so the tooth count would be different from the Audi anyway. Really great pics in that DIY though.

if you rotated the motor over and didnt feel any unusual resistance i would say it should be fine
