alternator is a pain in the hizzass. still got it done. helps to have an airgun and a lift to do that one. the other two should take about 45 minutes.
jack up car, put jackstands on. remove passenger front wheel. remove that splashguard. 15mm (i think) wrench for the tensioner, remove belt (not all the way)
10 mm on the waterpump pulley, yank that sucka, put the new one on. 14mm (i think, again) on the crank, yank that sucka, put the new one on.
on the alternator, remove the wire on the back, disconnect the plug. the wire is a bizzatch to remove (it's on a bolt). then the two (10mm?) bolts all the way out (again, a pain) then take a large flathead screwdriver to get it out of there b/c it's in all tight. drop it down to the bottom of the car.. what? it doesn't come out b/c the axle is in the way. if you dont have an airgun dont even bother doing this one (they are the same size anyway)
hit it with the airgun, put the new one on, and install
be careful, after you put these on you will have mad power and may burn up your tires real quick
