Default Water Pump Change

Okay, I'm in the process of changing my water pump on a 1995 Civic Dx, D15b7 Ej2.
The problem is, I've got to take off all the belts and whatnot to get to the water pump, I've got a Chilton AND a Haynes manual, but neither really clarify how to take off the drive belts, it's usually just something like " loosen the bolt."
Wouldn't be so hard, if there weren't a thousand bolts down there, haha.
If anyone would be able to give tips, or advice, that'd be great.
Pics would be awesome too!
Thanks!

Seriously, this is a fairly major job for a beginner. There is a risk of immediate and severe engine damage if you do it wrong. If you can't find someone more experienced to give you some in-person help, it would be highly advisable to have a pro do it.

ya i looked into doing it myself. But i came to the conclusion that it was a little too hard for me. So i took it to the dealer and had them change the water pump and all new belts which cost $475!!! It sucks, but if you talk to anyone they will tell you that its better to do it now before its too late.

well...I've already started, and there's really no point in going back now...
I've got the a/c belt off, as well as the alternator belt.
Both the manuals i'm using say to take off the starter, to get to the flywheel, and to stick a large screwdriver in the teeth of it.
Would you be able to tell me where the starter is located?

Also, I know I am a beginner at al this car stuff, but I really don't have 500+ bucks to have someone do it for me. I'm checking and double checking and triple checking everything I do.
I think it'll be good for me, help me learn more about cars, you know?
Good end of summer project too, I guess.

instead of taking out the starter, when you take off the underdrive pulley put the bolt back in and turn it that way. saves a lot of time

I looked up procedure to change timing belt on a different refence.
1. Remove Splash Shield
2. Remove PS pump (do not disconnect hoses)
3. Remove A/C compressor adjusting pulley with bracket and the belt
4. Remove P/S bracket
5. Loosen alternator adjuting bolt and pivot nut, then remove bolt.
6. Remove cruise control actuator

Rest is pretaining to actual timing belt stuff. If you need it I can type it up as well.

I've already gotten through all of that now, but thanks!
There was a write up either on here, or on honda-tech that had a step-by-step for a mini-me swap (which i wanted to do at the same time, but wasn't able to) and there was a write up for changing water-pumps...which has been very helpful.

*sigh*
this is such a pain in the butt.
<<
I got to the part where you have to take off the crank pulley. I was using a 4 foot breaker bar, with about 2 feet of extensions, to get to the 19mm bolt.
All was fine, I had the starter taken off, to get to the flywheel and shove the screwdriver in..yadayadayada...
Well, I apply pressure on the breaker bar, and I feel some movement. Push a little more, and it sounds like the bolt is turning! Wrong.
What happened was, the socket I was using ended up cracking, so it was pretty much useless now.
Crank Pulley: 1
Me: 0
Okay, so now I go to the auto parts store to get a new socket, head back home, and sleep.
The next morning, I get back up to work on it, start turning the breaker bar again, more movement, but not abrupt like last time. Soooo...it feels like the bolts is FINALLY loosening up. Wrong. Again.
Of course, I kept turning (I didn't know yet) and suddenly, the breaker bar falls to the floor. It turned out, my extensions are weak, and twisted, and snapped off. Cheap pieces of crap. >>
So, now, I've lost a socket, and 2 extensions. (one of the ends got stuck in the other, and is impossible to take out now.
Crank Pulley: 3
Me: 0
Last Resort:
My dad bought an air compressos yesterday (he's doing sometiling in the bathroom) so, I go and buy an air impact wrench, cross my fingers, and get to work.
No dice.
The air gun has 250 ft/lbs of torque, and still, it doesn't turn.
So, now it looks like I'll have to piece everything together, and take it to the shop, unless someone has some tips, or anything.
Soooo...
Crank Pulley: 4
Me: 0
What a week.

Those cheesy 250 ft-lb impacts are like your cheesy sockets: useless. Spend the $100 and get a decent 1/2" impact with at least 500 ft-lbs rating. (Clearly, that's what the last guy used to overtighten the bolt.) Also you want at least 100 psi of air at the gun. Make sure the compressor tank is filled above that and turn the regulator all the way up. Use a short air hose with a large diameter. Those self-curling thin plastic hoses restrict the air flow substantially.

The crank bolt is of course turned counterclockwise to loosen it, like any standard bolt.
