Hi, Sometime back I replaced a new timing belt. Timing marks were lined up accurately only to find that the belt was 1/2 a tooth out. I figured this was to allow for belt stretching? I have since had an untraceable overheating problem that started straight after this installation. Is 1/2 a tooth out enough to cause over heating.
I will soon be putting on the timing belt again but armed with a little more knowledge. I have a choice (as I did back then - can't remember!) to pull up the belt from the right stretching it anticlockwise over the camshaft pulley or vice versa. My tensioner is located on the left.
- Is it completely irregular to have a new timing belt 1/2 tooth out or is that to account for stretch.
I read somewhere that in this situation to put timing belt on in such a way that the tension in the belt should go to the tensioner side. (or something) 3 I'm now aware that depending which way I put the the belt on will have an effect of retarding or advancing the the timing. Am I right in thinking that I should err on to "advancing" to reduce the effects of overheating.
As much as I try I can't quite visualize exactly the approach I should take - can anyone offer a little clarity?
