So I am thinking on embarking on my Civic’s timing belt replacement journey. I just recently replaced one in a Chrysler minivan with the Mitsubishi 3.0. I was just pondering a few thoughts in my head.
When we did the timing belt in the minivan we had one issue with one of the camshafts being under load and wanting to snap forward or back. Good thing it was an non-interference engine or else it would have been difficult to sleep that night. I was wondering if I would be experiencing anything like that while working on the Honda 4 cyl engine.
Also I was wondering if I should really replace it. The car currently has 82k miles. I bought it used at 81k miles ago and I am unsure if it was ever replaced. I bought it at a shop and they claimed it was good until 120k, but they are wrong…by a long shot.
I already bought the crankshaft holding tool. That was a big problem we had while working on the minivan.
Any input is appreciated.
I also have watched this already. http://www.youtube.com/watch?v=AoJcAS58CHg

Lets wait for someone to jump in. I have been thinking about it so much I think I have it confused now. I have been looking through my old videos to try and find the ETCG replacement that was purchased. But no luck. Someone knows.
Thanks for the help. Tomorrow I may try to take the belt off one more time and just re-install it. I don’t really remember what I did now…
Does Eric still respond around here?
I finally found a video of what best represents the issue I am having. It’s not that extreme, nor is it that loud. It’s just the basic situation with the flopping belt on the exhaust side.
You want the side of the belt that faces the front of the car to be tight. Put the front side of the belt on first. Then the back side, that goes around the belt tensioner. The belt tensioner should be loose when putting the belt on. Pull up on the tensioner, and tighten the tensioner bolt.
This was taken from Mitchell On Demand. I condensed the instructions to make it easy.
Rotate the cranckshaft 5 or 6 revolutions counter clockwise and set the crankshaft at TDC on compression. Loosen the tensioner bolt. Turn the crankshaft 3 teeth counterclockwise to put tension on the belt. Tighten the tensioner bolt.
THAT’S IT.
It’s normal for the belt to flap somewhat. Make sure the timing marks line up and put her together.
Wysetech- I’ve been doing that, but the front side of the belt still flaps around. Sometime it’ll be good, but as the engine spins around, I think, but am not 100% sure, it starts to loosen up again.
cb7ftw- I am pretty sure I did that, I might try to take the belt off one more time and put it on.
If the tensioner bolt is tight it can’t get loose. If you get the belt too tight it will be noisy. If you push on the belt about midway on the front side it should deflect about 1/2 in.
Like Eric said…Like a banjo string.

Ah so about a half an inch? Maybe I will make a video of the engine running and post it to youtube.
I made a video of just me flexing the belt.
I’m sorry but it’s too loose. Are you sure that you have the correct belt? You have to loosen the tensioner and turn the engine counter clockwise while tightening the tensioner bolt.
Does your tensioner have a spring? Similar to the 3.0 you did.
I just reviewed Erics video and personally i like his procedure better. When setting the tension he holds the cam pulley while rotating the crankshaft counterclockwise. That takes all the loosness out of the front side of the belt and tensioner should tension the belt correctly on the back side if the spring is pulling the tensioner toward the belt. When you tighten the tensioner bolt it should be good to go.
I re-did the tension procedure and it barely vibrates now. I did his procedure and then did something similar. It is all back together and doesn’t squeak or make any noise
Thanks for all your help.
