Sorry not available in my alldata book ,as for alternator bracket this should be easy to change without any diagram for a proper mechanic worth his salt. Bring engine to TDCno1 but taking the plug out and lower a long thin screwdriver do locate TDC then paint the gears with white paint before taking the old one off .

How do you get the alternator out of a 2003 Focus SE, 16V Zetec DOHC?


Disconnect battery ground cable
Remove the ground wire (black) from the alternator
Disconnect the positive wire (red wire held on by a retaining nut) from the back of the alternator
Now disconnect the wire harness from the alternator
Remove the drive belt
NOTE: Some models use a belt tensioner that applies tension to the drive belt.
The best tool to use for this job is the serpentine belt too.
If you can borrow one from a neighbour you can get one at PartSource. (Part# 648451)
On other models you will have to loosen the adjusting bolt on the alternator bracket.
If you're not sure about how to remove the drive belt, visit your local PartSource for free print outs of car specific instructions.
Take off the mounting bolts from the alternator bracket
Now remove the alternator from the engine compartment

Installing Your New Alternator
Put the alternator in the engine compartment
Install the mounting bolts that connect the alternator to the alternator bracket
Connect the alternator wiring harness
Now connect the positive wire to the alternator
NOTE: Your new alternator should come with a retaining nut.
Remember to remove the nut before you install the positive wire.
If it doesn't keep the old nut.
Connect the ground wire to the alternator
Now install the drive belt
This is a great time to replace your old worn out belt. When inspecting your old belt look for signs of cracking, oil soaked, hard glazed, splitting or fraying.
All these signs mean it's time you replaced your drive belt.
If your vehicle no longer has the belt routing diagram under the hood, visit your local PartSource for a free print out of the belt routing diagram.
Reconnect the ground battery cable .

Does anyone have a diagram for a 1978 caprice alternator belt?


I can't send you a diagram,but it's not too hard to explain. Loosen off the alternator first. Two bolts, one you can see that goes through a bracket on the engine and another that is directly under that bolt on the bottom of the alternator that goes into the engine. Fit your new belt over the fan first, one blade at a time and on the pulley. Run the belt down to the bottom crankchaft pulley and then across to the alternator. Before you tighten the belt make sure that all 3 pulleys are in a straight line when you look from the side. If not move them so they are. Take a long screwdriver and put it in the hole on top of the alternator bracket and pry the alternator over so the belt is snug and a little bit more. Tighten the top bolt first,but be careful because it can strip the threads. Then tighten the bottom bolt.You will probably have to retighten it after a few days because the belt will stretch. If the belt squeals when you start or rev the engine then it needs to be a little tighter. If you strip the top bolt, just take it out and find a smaller one with a nut and washers and use it with the washers on the front to keep the new bolt from pulling through the bracket. Hope this helps.

1993 jetta 111 series, over heating.


well here it is, hope u have a few hours (or a couple days, depending on ur mechanical skills)
remove the alternator and belt, remove the support bracket for the alternator and remove the water pump. The water pump is a big assembly and is also the support bracket for the alternator. This is a pretty hard job to do and i suggest u have it done in a garage because the 2 top blots holding the water pump are very hard to get to.

While ur at it replace the water pump at same time, this is EXTREMELY RECOMENDED.
