Default h23a1 timing belt install question



#20 says to "Tighten the 6x1mm bolt to lock the timing belt adjuster arm", i've put a red mark on the diagram. now my question is shouldnt the spring loaded tensioner be free to pick up the slack after the belt stretches over time???

No. That's why it's called a "manual tensioner". The bolt and bracket in question is meant to hold the tensioner in place so you can tighten down the main adjusting nut.

No, because first off; if you have no bolt there and the other bolt slips you just lost all timing alignment, your engine won't run right, and you may bend some valves. Those little springs are not that strong anyway, I usually have to pull up on the tensioner with a coat hanger to get an H23 timed just right.

Second thing; the goal of a timing belt is to not stretch over time. It's made to be strong and stiff, so if it flexes you also would loose timing alignment and that woud defeat the purpose of a (good) t-belt.

I woul just get a spare 10mm bolt (10mm head) and install it in that spot to make sure your timing adjustments stay.

thanks, i just wanted to make sure. i've already installed the belt, dropped the motor like 2 months ago. i wasnt sure if that bolt was supposed to come out, but i left it in like the manual says. just wanted some clarification before i start driving my lude on a daily basis, so disaster doesnt happen again.
