I have a Ford F150 4x4 I beleive needs the alternator replaced.?

Question

It is a 2000 F150 4x4 4.2 with air conditioning and is a standard shift.I need to know how to determine how many amps it is.There are few different ones out there and I don't have the original owners manual.I just got laid off so I need to do this repair my self what can I use to move the tensioner back so I can change this?I also have a leak in the back window, how do I get at the gasket. I see small plastic caps on the inside of the cab covering nuts,do I have to remove them to take the outside plastic frame off and will the glass stay in place if I do? Thanks for any help.

Answer 1

Firstly, let me say that your F-150 is a very unusually equipped model being a 4.2L V6 with a 4x4. But enough about that.

Since you mention that it is equipped with A/C, it is for certain that you are equipped with the alternator that puts out the higher of the two amperage ratings, which is 130, if I recall correctly. To release tension from the serpentine belt, requires a long 15 wrench (or using the "double wrench" trick for better leverage) on the tensioner pulley, which is the next one down from the alternator on the passenger side of the engine. With the wrench on the tensioner pulley bolt, pull UPWARD, and slide the belt of the smooth side, while leaving the belt routed on the rest of the other accessories. Next, disconnect the negative terminal of the battery, using an 8mm or 5/16" wrench. To remove the alternator, start with removal of the battery terminal on the alternator, using a 10mm wrench to remove the nut. Next, remove the two electrical connectors by releasing the lock tabs on the connectors and pulling gently. And lastly, remove the alternator by removing the three bolts that secure it to the mounting bracket on the passenger side of the engine, using a 15mm socket and suitably sized ratchet/extension combination. Installation is just the reverse of removal. I would like to mention that you are better off replacing it with a Ford/Motorcraft alternator to save on headaches, even if it costs double what an aftermarket one costs. I have seen aftermarket alternators go bad within less than a year, or even out of the box, TOO MANY times!!!

Regarding your rear glass, YES you are correct, it DOES require removal to access the outside plastic frame around it. Unfortunately, it is a fairly tedious task that is better left to a trim and body technician, due to the delicate nature of the way it needs to be handled. The margin for error is extremely slim in that the rear glass can shatter VERY easily at any moment during the repair. Again, you are better off contacting your local "Water Doctor" or a shop specializing in auto glass for an estimate.

HOPE THIS HELPS.

I'm not a "auto glass" expert, and if you need one, contact one. As far as I know, the trim around the outside of the window can be removed without touching anything on the inside (a set of tiny pry bars and picks) but I could be full of sh-t. If your leak is from the adhesive that is used to secure the window in place, the window should be removed and reinstalled correctly. The window is part of the structural strength of the cab.
As for the alternator, again look into what Eleanor Baby has. The AMP rating is stamped onto the alternator case or voltage regulator, and this is what you must rely on if you are going to rebuild it. To get the belt off, pull on the belt (somewhere with a long section between pulleys) to see which pulley is the tensioner (it should move) Now attach a socket to that pulley bolt (if there is no room, use a long wrench) and let the tension off while removing the belt. In some cases, there is a square hole just above the pulley that you can just put a short extension on to turn it.

Answer 5

First of all I used a F-150 twd to tow a 3500 pound boat (with all the gear and fuel, it was used for off-shore fishing was most likely between 4500 and 5000) for about two years, and would recommend getting something bigger (I did) because it just didn’t have the power to handle well. It is about 120 miles to where I put in to fish, about half the trip hills. But it will work if you are willing to put up with not real good performance. A little trick we found out of desperation (couldn’t get the boat out in a low tide situation and no one else around to help) in getting boats out of the water when only having two wheel drive, use the boat to “push” the truck out. What we do when the tide is out and the truck is on the wet slippery part of the landing, or if we go somewhere the landing is very steep is to have one person in the boat and put it in gear, and when the truck starts pulling hit the gas on the boat hard for a very short time. This allows the truck to start moving, and also gets enough of the boat out of the water that the tongue weight on the trailer helps hold the back of the truck down without putting a load of people in it. Just very quickly cut off the boat motor before it gets out of the water. I now have a F-150 5.6 (unbelievable how much difference that little bit made) 4x4, and is much easier getting out and much better performance towing.

Hi Eddie-
While I am not a service technician, and cannot offer qualified repair advice, I can help you with part of your question by providing you with a free owners manual for your vehicle, since you mentioned that you don't have the originals.

The digital versions of your owner guides are free downloads (in pdf format) from the Ford website.
To make it easier for you , I'll provide the link.
Just click on it for the owners manual & save it to your computer for future reference:
http://www.motorcraftservice.com/pubs/content/~WOYF12/~MUS~LEN/36/00f12og5e.pdf

This is the 'click-on-link' to download your maintenance schedule:

http://www.motorcraftservice.com/pubs/content/~WOYF12/~MUS~LEN/35/00a00mg3e.pdf

These are NOT repair manuals but they do contain valuable information.
I have skimmed through both publications & was unable to locate the the alternator information that you need so I am going to forward your question to a qualified technician, within my network.

I hope the owners guides are useful to you ;-)

Answer 7

somewhere on the alternator the amperage will be stamped
you have to look close it will say example 105a that is 105 amp alternator the tensioner will either have a square hole 3/8 or 1/2 that you put a ratchet in or ther should be a hex you can put a wrench on be careful as they are spring loaded

Answer 8

If you have a auto store nearby, you can probably have them test the alternator for you. They will also know what size your current one is. Auto Zone is good for this stuff. They'll test it for free and get you the right stuff.

If you don't have a job, just get a clear silicone to try and seal the window. Replacing rubber isn't the easiest thing to do and if you crack your window, was it worth it?

Good luck.

Answer 9

yea take it to auto zone or checker they can tell you if it is a alt, battrie starter . could just be loose battrie cables or dirty and need cleaned.

Answer 10

that sucks .most parts stores will test it free.autozone.com
