Serpentine belt change

Ok, before I start, I have tried a search, but couldnt' find exactly the answer I was looking for.

I would like to change the belt on my car. I've found the tensioner, and I know what tool to use to loosen it, but my question is which part to loosen? As I look at it, there are two parts to the tensioner, the main body, and the outer wheel (the part which actually tensions the belt).

http://www.onlinewholesaleparts.com/hbt0001.html

Both seem to have bolts, but I'm not sure which one actually needs to be manipulated to loosen the belt. I don't want to strip the one that's not supposed to move.

Also, does the tensioner need to be changed at some point? I had a friend who's tensioner died, and now that I"m in the know about that as a possibility, I didn't know if that would be a potential maintenance issue.

Thanks for anyone's help.

Pretty sure it's a 14mm bolt, here's the scans:




My car is stock, I promise.

Yep, you're right, 14mm. The damn autozone guy told me it was 15 (when I rented the kit), it had no 14mm bit, I have no 14mm bit (for some reason, but I have 10, 12, 13, 15)

Luckily, 9/16 is pretty close to 14mm, closer then 15mm is to the actual bolt. Too late I've already started to strip the tensioner bolt.

I may have answered my own question about replacing the belt tensioner. At least I have the scans to do that (thank you horro).

While I'm on it, does anyone know how loose/tight the belt is supposed to be while the tensioner is torqued? I could only get the belt about 1/3 the way around the upper most thing (power steering?) around the belt, and not nearly enough to loop it around.

This was supposed to be easy....

FINISHED

You must use a lowlowlow profile 14mm socket. The kit I rented did not have one, only 18, 16, and 15mm bits.

Good info as always AWOC!

This would come in handy doing a crank pulley or under drive pulley set - yes?

It's not strong enough for the crank pulley. This and a long 1/2" breaker bar will do the trick Honda/Acura Crankshaft Pulley Holder (7315) - Doughboys Tools & Equipment.

Newbie here and just used this thread to help change my belt. Thanks all.

Couple quick points

I used a 1/4" drive with a 14mm socket and just put the closed end of a longer open end wrench around the ratchet to get more leverage. Worked great. As we know the 3/8" is too fat.

..and like the pic shows, pull/push to the front of the car.

Thanks again all for the help.

Another trick, this one for getting the belt back on, is to route the belt around all of the pulleys with "lips" on the edges, and use the tensioner pulley (no lip / just smooth) as the last one. That way you can slip it on without needing to pull the tensioner pulley really REALLY hard/far.
