Trying to tighten timing belt

lanos · Post by **lanos** » Sat Nov 08, 2008 2:48 am

I recently loosened my timing belt by hand but want to tighten it well with a tool. There are no tools in my posession that will fit behind the coolant pump and adjust the tensioner. I have a diagram that says to use a timing belt tensioner J-42492 but am not sure what that is. I think it is like a "crows foot". (An open-ended wrench with a fitting for a ratchet to rotate it.)
Has anyone had to tighten the tensioner and if so what tool did you use? I don't know if its possible to tighten it with anything else due to the lack of space behind the tensioner. thanks!

from what ive heard you need a 42 mm open end wrench.

What I just did recently on my Lanos (replaced water pump, tensioner, timining belt) was to leave the water pump bolts loose. I set the parts alignment and released tension on the tensioner. Turned out I needed more. I locked the tensioner back in place and and that point I was able to turn the water pump by hand. Got everything right at 3rd attempt, without the use of 42mm special wrench tool. Hope this helps.

Someone use channel lock pliers.

But I made my hi-tech tool from dimensions I've found on our forum.

Quite crude. I reduced opening to 41mm.

I made my own timing belt tensioner from the specs of 42 mm that daewoomofo sent me and it worked. thanks for the help guys. Now its time to take apart the head.
