Hi im trying to change the alternator on a isuzu
Ok changed one today , here we go :
It sucks get over it now!
Go to right wheel arch pull back rubber splash guard, you will see the altewrnator, oh good idea is to turn the steering all the way to the right, this gives you more space to work in the wheel well.
You will need 14mm through 11mm sockets I think and open mouth wrench's.
Disconnect the live side of the battery NOW.
Loosen the top bolt , it takes patience and a gentle pry bar but it will move .
Now looses the bottom nut and remove it , this lets the alternator hinge on the top bolt.
Get underneath the alternator and support with one hand as you undo the top bolt, it should drop a bit 1" or so.
Now disconect the bolted lead and the 3 pin connector, the alternator is free now .
Now comes the really friggin frustrating part , you need to get the alternator out of the gap in the wheel arch you initially started at.
Sorry I can't describe how , you just have to twist and turn it till you work it out , but take my word thats the only way its coming out.
Oh yeh some where in there take off the belt ( had a moment there).
If it all gets too much you can take off the bracket that is used to adjust tension , its a **** to get off and an even bigger **** to get back on , but I did it today in 103 degree heat and didn't shoot or kill anything , good day eh?
Once the alternator is out go get high or drunk , cos you've got to do the whole thing in reverse,man that blows take my word for it.
Good luck mate , I tell it how it is enjoy.
