Hello all,
I started to replace my wife's water pump over the weekend. I'm also going to change tensioners and belts while I'm at it. After removing the crankshaft pulley, I know that I have to line up the timing marks on the camshaft and the crankshaft pulleys.
When the camshaft marks are lined up, the crankshaft marks don’t line up for some reason? The mark on the pulley is about 30 degrees to the left off the mark on the cover plate (or about an inch if looking from the top)
Watching videos and reading forum posts, I know that they are supposed to line up before removing the timing belt. As far as I know, the belt has never been changed before (84K miles) and we’ve had it since 2005. The car runs fine which confuses me. I won’t take the old belt off yet until I understand what is going on.
Does anyone understand what is going on?
Thanks.

You might want to recheck your timing marks but use the flywheel marks, rather than the crankshaft pulley. It is possible for a worn crank pulley; to have the outer portion to slip if the rubber is degraded or worn out (thus the marks move).

Pull the # 1 spark plug and inserting a screwdriver; can also be another way to confirm tdc.

Check out the service manual for more info: (note the flywheel marks)

OK, thanks for the reply, I will have another look tonight and check. My brother mentioned something similar about degraded rubber.

timing marks

First get the timing marks pretty close to TDC.
If the car is running fine.
The timing marks don't have to match or align exactly. What's more important in order to not mess up your timing is to mark the belt and sprocket with nail polish or some permanent marker before you remove the timing belt. Starting from the top cam you will place a mark on the belt and on the cam wheel sprocket & also put an arrow going clockwise. Then do the same to the crank pulley and belt there, but no arrow. Now you can remove the belt. Then count the number of teeth on the old belt going clockwise from the top cam & arrow until you get to the crank sprocket marks. Double count and triple count to make sure. Then mark the new belt with the same amount of belt teeth and put an arrow to keep things simple. Install the new belt by just matching up the markings on the belt to the cam sprocket and crank sprocket markings.....You can't go wrong like that. like they did in this picture where they used orange color on the cam pulley.

It is in top of the bell housing of the transmission; click on the above link to. the service manual pages. go ahead and print out all the pages about the timing marks and that way you look at them, when you're working on the car.

I did click on the link and when I finally find the inspection hole I will be able to figure it out. The car is an automatic if that makes a difference and this is the first time I've looked under the hood/bonnet; its my wifes. Do I need to remove anything to find because I cannot find it anywhere?I assume the bell housing is on the drivers side? I have no idea. I drive Mustangs and corvettes and that is what I'm familiar with. Please excuse my ignorance.

Is this the inspection hole? just under the second vertical stud, about an inch diameter. I found this image in another post. If it is, I guess this is for a manual trans? I assume the automatic is in the same place?

Thanks for the image, but I give up. All I need to know is where in the engine bay do I need to look???? Maybe I'm asking the wrong question. I guess I'll have to go to the VW dealership 50 miles away and ask them; maybe they can point with their finger.

Thanks for everyone's help.

End of thread, no need to reply.

You'll be looking from up top, down onto the transmission. This may help some.



The engine is at the top of the image. The inspection hole is in the bellhousing. It is under some hoses and things but it can be seen without removing them.

flywheel timing mark

That is where it's at in the picture that smileybug is showing but on the 1.8t engine you do have to remove the airbox and maybe the SAI pump hoses to see it. It's gonna have a rubber plug and so you just pull up on it. TIP; Once you locate the timing peep hole on the bellhousing then you can slowly crank the engine a little at a time until you see the timing mark on the flywheel. Or at least get it close and then turn the engine slowly by hand using a 1/2 ratchet and turn the bottom crank sprocket clockwise.

Thank you very much Smileybug and esse10. I actually removed the air box the other night and I’m going to remove a few hoses because it’s still not visible. I know it has to be in there somewhere but at least now I know the correct area to look at. I probably won’t get round to it before the weekend but I will update my progress when there is something to tell. Once again, thank you for being patient. Hopefully once found and with help from billymade’s service manual images, it should be a breeze from now on?!?!?! lol

Well just got home and had a look and I think I can see a hole under a s**t load of hoses. I need to get a pen light, mirror and magnetic stick to see properly. I have them somewhere but I can't seem to find them!

This is what to look for a rubber plug like the one in this picture that the red arrow is pointing to.

I FOUND IT I FOUND IT I FOUND IT I FOUND IT I FOUND IT!!!Thanks for the image, it confirms it. Mine didn't actually have a stopper in it, so the flywheel was a little rusty. I eventually took #1 plug out and got it approximate then looked at the flywheel and I could just make out the timing mark. Thank you, everyone who helped, it was invaluable. Putting it all back together tomorrow will be the easy bit?!?!?!?!?!?

The timing marks were still off the balancer so it leads me to believe that the rubber has degraded on the pulley. I was toying with the idea of replacing the pulley but at around $300 for man OEM replacement, I'll make do with a bottle of nail varnish and make new marks.
