Alternator how do i remove ???
Discussion
Guys,
Got to the bottom of the rev-counter issues, tested the battery all ok just under 13v, ran the car and it dropped to 11.9 so im thinking alternator must have died when changing the starter.
When i tested the actual alternater it was showing just under 12v but did not increase when i revved the engine, now to save me taking everything of that i had to when changing the starter can i get away with just taking the fuel rail off ??? and if so is there a technique to this or any tips etc ??
Thanks in advance.

If it's a 4.5 then you have to remove the air intakes, fuel rail and injectors.
The alternator will come out forward without removing the throttle bodies but it fiddly. so if you have air con then you have a choice of removing Throttles or air con pump. If you go forward you will also need to remove the bracket the alternator is bolted to and take this out first. there are 4 allen bolts two up front easy to get to and to at the back a little awkward to get to. Round headed allen keys make this a lot easier.
A problem I had was that the heat barriers that are fitted between the T.Bodies and head one was fitted the wrong way round and prevented me from manoeuvring the alternator so had to take the Throttles off.

As you have a 4.2 you will want to take the manifold off complete with the fuel rail (as per for changing the starter!)
Believe me it is far, far easier to get them back on if you take them off as a unit. If you take the fuel rail off separately it is a complete nightmare to get the injectors back in without chewing up the O rings. So much so that you will take the manifold off just to put the fuel rail back on to it off the car.
I am not sure that taking just the rail off would give you enough room to get the alternator out anyway.

i was thinking i could slide it out the front if i took off the a/c pump ( its out of gas anyway) would this be possible ??Believe me it is far, far easier to get them back on if you take them off as a unit.

Hi Wiggy,
Sorry if I am stating the obvious here.... but have you checked the big fuse?
Hi yes even changed the new one i put in a few months ago .... coming to the conclusion that the alternator has died, although i think a trip to the auto electrcians should finally resolve it !!!Sorry if I am stating the obvious here.... but have you checked the big fuse?
