I installed my Power steering, and helped on the timing belt.

But the a/c belt is a little more tricky since I don't know where the tensioner is at.

Can someone help me, or show me a how to. I just wasted 10 mins on google, and all I found on H-T was ALL on timing belts.

 

Don't konw what year your car is, but for the 92-95 civic. the ac belt tenssioner is on the left hand side of the valve cover (when looking at the belts from the driver side fender) the adjustment bolt (10mm)is between the timing cover and the power steering pump bracket. You will need an extention to get on the bolt. Once you find that you will see a pulley that the ac belt goes around this pulley has a 14mm bolt keepping it tight. You will have to use a long box wrench to reach the bolt. You only need to loosen the nut a little bit. This will let you adjust the tenssioner bolt to loosen or tighten the tenssioner. Once you have everything where you want it tighten the 14mm bolt back up and you should be good to go

 

On B series its very hidden beneath the PS Pump. I had a hard time finding it myself. Good luck!

 

Its a 99 EX. Stock D16y8. So it might be the same as the 92-95?
