Removing Timing Belt on a 1g

[rgaulding]

I'm trying to remove my timing belt on my 90 1g but can't figure out which pulley is the tensioner. So other than locating the tensioner I need to know how to relieve the the tension to pull the belt off without destroying it. I'm doing this so I can pull the head off and replace the head gasket. Pictures and detailed instructions would be greatly appreciated!! THANKS!

Check the Vfaqs

Yep vfaq.com or a manual, tensioner releases the slack nothiing else. Might as well remove the cover and do it, your gonna have to anyway to change the belt out.

Thanks for the link, thats one of the reasons I love this forum.

And I know all its going to do is slacken it but the belt is still new and all I need is some slack to slide it off so I can pull the head off.

Ok so that link has great instructions but no pictures and I have no idea which pulley is actually the tensioner. And it mentions special tool, what sort of thing is that suppose to be and can it be substituted?

Loosen the tensioner slide the belt off, then pull the head.

Glad you figured it out. Just to make it easier for people searching in the future, here is the image with the part names:

and here is the link to the 1G timing belt VFAQ: Timing Belt VFAQ (Timing Belt TSB - ENHANCED)

Keep in mind that there are 2 tensioners, the hydraulic tensioner and the tensioner pulley. Make sure you reset the tension on the hydraulic tensioner or better yet, if you don't know the last time everything was replaced, replace all of the timing components so you won't have to worry about the belt snapping or jumping time once you get everything back together.

Hope this helps!

1 last thing, anyone know of a good way to not need that special tool for this? i don't a battery hold down rod anymore (I don't think) so I can't create one the way they are talking, I might have a long bolt I can use but I don't know the thread pattern and DO NOT want to cross thread that hole.

Yeah, get a piece of rod the right size and length. Then thread it to match the hole in the tensioner.

Any idea on the ball park of that size and length or the thread pattern?

The thread is 8mm x 1.25 and the length is 8" with the first 3" threaded.

M8, they are usually like 3' just put some kind of rod into where the tool goes to measure the distance then lay it against the threaded rod and cut to length.

They also sell the other tool to fit the pulley to get a wrench on it,

Thanks for everything guys. I went to the hardware store and bought a bolt 8-1.25 150mm for $3.70 and then just tapped the threads longer and it worked perfectly.

don't f*** up, the guy that changed my timing belt, did it wrong, and it snapped while driving, damaged my head so bad, all of my valves were bent. had to get a new head.

Ya, I built my own tool with the 8mm rod (about 10 inches long) and two 13mm nuts on the one end where I jammed the two nuts together so I can use a 13mm socket on the end...
