Can anyone tell me what size the bolts/nuts are that secure the alternator to the alternator bracket?

ADJUSTMENT

Excessive belt tension will cause damage to the alternator and water pump pulley bearings, while, on the other hand, loose belt tension will produce slip and premature wear on the belt. Therefore, be sure to adjust the belt tension to the proper level.
To adjust the tension on a drive belt, loosen the adjusting bolt or fixing bolt locknut on the alternator, alternator bracket or tension pulley. Then move the alternator or turn the adjusting bolt to adjust belt tension. Once the desired value is reached, secure the bolt or locknut and recheck tension.

disconnect the battery & make sur you have your radio code, then remove the belt.
it's pretty simple there's a nut in the middle of the tensioner wheel, get the right size socket & using a ratchet, move the tensioner by locking the rathet & do or undo the nut, as it's a fixed nut used to swivel the tensioner.
Then undo the wiring on the back of the alternator, usually a click in multiplug and a + power cable boted on with a 10mm nut.
then remove anything in the way of the alternator securing bolts, & remove the bolt's, alternator should be free !
But I don't suggest you do it yourself unless you have a reasonable grasp of mechanics, as I have had to do this job properly after some people have tried themselves & they've made it worse, plus once the belt's off you have no power sterring so you can't drive it to the garage if you can't get the belt back on !

You need to first take off youre serptine belt. Inspect that and generally its a good idea to replace. Next there is a electrical connection on the alternator. DISCONNECT the battery FIRST!!!!!!!!!!!!!!!!!!!!!!!!! then disconnect the connection on the alternator, there are a couple of bolts that attach the alternator to the engine. and then simply bolt on the new one, re-attach the electrical connection and then re-install the (new) belt.

This is for both size engines since you didn't list the motor size......
