4 cylinder alternator removal

I just changed mine b4 driving to the 20th.

1. Remove dog bone / trunk wall bolt. 2. Loosen other dog bone bolt and rotate bone onto valve cover. 3. Jack up passenger side. Put on jack stands. DISCONNECT BATTERY. Remove serpentine belt by cranking tensioner pully bolt clockwise. 4. Remove rear passenger wheel. Remove lower alternator bolt from underneath / wheel well. 5. Remove alternator bracket to alt bolt from on top. 6. Hinge alternator towards trunk. This will make electrical connections more accessible if you have A/C. Disconnect electrical connections at alternator. Remove alternator hinge bolt. 7. If you have an automatic like me, remove bolt that holds trans dipstick in place. Rotate dipstick out of the way. 8. Push engine towards passenger compartment while removing alternator at trans dipstick location (two people or some device to hold engine required). 9. Install in opposite order.

When I replaced my serp belt, I had to rotate the engine by wrench on crank bolt to make it ride onto one of the larger pulleys. Apparently the new belt was a tight fit. (I turned the crankshaft while my partner held tensioner at loosest point.)

I also broke a rubber vacuum line from throttle body to trunk wall. $1.50 fix.

88 4cyl auto Fiero, AC, sunroof "And isn't sanity really just a one-trick pony anyway? I mean all you get is one trick, rational thinking, but when you're good and crazy, oooh, oooh, oooh, the sky is the limit!" - The Tick

ANOTHER COMMENT:

If you need it, the drive belt tensioner is a dealer part, GM #10041248. It lists for $68.31 at gmpartsdirect.com or $59.21 at paceparts.com. The tensioner also seals the end of the engine water jacket. As the Ogre says, that part goes out quite often.

Also, you can get the alternator out without removing the rear wheel. You do have to push forward on the engine (dogbone removed) and move the alternator to the left side of the engine to remove it. Helps to get the throttle cables out of the way first.

make sure the pulley nut is tight on the new alternator.

DIPSTICK: On an automatic you'll have to be really careful about the dipstick tube. You may have to take out the bolt that supports it and turn the tube. (Don't pull it out.) Be warned that this could start a leak and you may have to replace the O ring on the tube later.

DOG BONE == Torque Reaction Strut

ANOTHER GUIDE

1. take upper alternator bolt off
2. remove charge cable and side socket
3. remove lower bracket bolt
4. remove lower alternator bolt

TIP ON REMOVAL VIA TOP

• fish the alternator across the engine till it's over the transmission and then lift it out. Helps to loosen the dog bone and rotate the engine forward to get more clearance.

ANOTHER GUIDE

1. remove Torque Reaction Strut
2. remove adjusting bolt from top of alternator
3. remove belt
4. tip alternator all the way back
5. remove 3 bolts that hold the bracket from the engine and remove bracket
6. remove pivot bolt/nut
7. disconnect wires and lift alternator out
