removing waterpump???

The block drain is under the header pipe on the right. It can be reached either from the back of the car or through the wheelwell with the inner liner removed. You should be able to get to the alt. when the inner line is removed.

 

Access is the easiest by removing the wheel and inner wheel liner. Access to the tensioner bolt and brain bolt are quite easy. Just be sure to make some sort of funnel to drain the block so the coolant doesn't drain down all over the Axle CV seals. This is the cheap-o one I made out of carboard... not pretty but it works

Block drian is right under the #1 cylinder exhaust manifold.

 

Attach picture is best I have (alt is lower right)... never took a photo of just the alternator yet. I belive it is located on the right side of the alternator if my memory serves me right.

What year is your 308? You should not have to touch alternator to get the water pump and housing out. See Pic below... four bolts and it comes right out on an '83 - '85

There are two bolts you must loosen to remove slack from the alternator. The first bolt is the "hinge" bolt (enables the alternator to swing) and should be directly in front of you. The second is the bolt that holds / removes tension to the alternator/belt...this is the tough one, the one tucked up behind the A/C unit.

When you complete your work and its time to tension the alternator, its best to have a second set of hands to apply leverage to the alternator while you tighten down the tension bolt / nut. Hope this was helpful.

 

"C" is the "adjustment bolt" that slides in the bracket slot, but the other "hinge" bolt (not labeled) must also be loosened as Greg mentioned:

Joe the hardest thing about loosening the Alternator belt is jacking the car up and removing the wheel. All jokes aside its really easy to access.All you need is a 3/8 drive ratchet with a short extension and from memory a 17mm socket

 

He has a 79 so won't he will need to remove the timing belt cover to get to all the water pump bolts, unless his car has been modded?

 

Laying under the car looking up at bolt "C", with several extensions and a swivel socket, you can snake these extensions coming from the drivers side. Once again, loosening has never been my problem, it's the tightening part because the minimum belt deflection required...it really requires a second set of hands to be 100% sure you are tight enough.
