I actually cover that in the timing belt video posted on the Tools page of this site however the process is very similar to what I show in this video on a Civic engine.
Thanks Eric. With my engine it also has a balancer belt… do you advice keeping that belt quite slack? I have the timing belt nice and tight but I left the balancer looser this time which fixed the noise. I may have to replace the tensioners at some point as the car makes a sound like this one – (not the first bit when the window is wound down but when they rev it slightly) http://www.youtube.com/watch?v=shMCT7yuXpA I am pretty sure it is the tensioners because it comes from somewhere in the timing covers. The waterpump was turning freely without grinding when I was in there so its either the tensioners or something else going on.
Let me know your view on this one.
9 times out of 10 noise from the timing belt area is caused by improper tension of the belt NOT the tensioners, on that engine if you use the method I showed you you will be setting the correct tension on both belts at the same time as they both use the same hold down.
I got the same noise from my car as you have mentioned of yours and the same sound for sure after watching the youtube video. Is it too tight that causes this?
Question I have is: Do you have to do a complete tear down to re-adjust the belt or is there a “cheat” to getting it re-tightened? mine is a 2001 civic dx.
You don’t need to tear it all down just loosen the adjusting nut and set the tension, there is a quick overview of how in this video. You don’t set the tension by prying on the adjuster.
Thanks Eric. Very much appreciated. Doing a valve adjustment this week on it as well so good time to get both projects outta the way. Seen video before but had forgotten about it.
