How do you replace the alternator?
2000 Honda Accord V6 Here is how I went about replacing the
alternator for this model. 1. Take out your car battery and have it
charging while you work. 2. Loosen up your power steering
container. The hoses can stay connected. Just loosen the bolt. 3.
Undo all of the electrical clips that are on the fan so that you
can remove the entire fan. There are two bolts on the top and one
bolt on the bottom. I reached down with a 10mm socket and took it
off (If you have trouble try putting the socket on the bolt and
then the wrench into the socket for an easier fit. The fan should
lift completely out. The hardest electrical clip will be on your
lower left. That one is actually just clipped to the fan so unlike
the others, you're taking it off the fan and not separating the
wire plugs. Raise your fan out. 4. Take out the green plug off the
alternator. 5. On the right side of the alternator is wire going in
that is covered by a rubber plug. Pull off the rubber plug and use
your 10mm socket to remove that bolt. 6. Loosen the pulley for the
alternator. The bolt you're looking to loosen is NOT the large bolt
of the pulley attached to the alternator but rather the next one
back (back as in towards the back of the car). Just loosen the bolt
(14mm I believe) in order to take the belt off the pulley of the
alternator. 7. My next advice is to loosen the clamp that you'll
see on top of the alternator (your green plug wire runs through
this. Loosening this up will make taking the alternator out a
breeze and is a cinch to loosen up. 8. Take out your two primary
bolts holding the alternator in. 12mm socket should do this for
you. 9. You should be able to pull the alternator out with ease
especially if you followed step 7.
When checking the price of your replacement alternator be sure
to know what the cost of your alternator will actually be. You'll
see the price plus the core cost. By this they usually mean $145.99
Core $50. This means you'll pay $195.99 if you don't bring your old
alternator (IE your Core) in first. If you do, you'd pay $145.99
plus sales tax.
Tools: Have a set of wrenches, sockets (14, 12, and 10mm), and a
pointer magnet is highly recommended.
The whole process is rather easy if you know what you are doing.
I didn't but now I do. I've tried to include the basic information
I didn't know. Good luck! You can do it.
To start, REMOVE YOUR NEGATIVE BATTERY TERMINAL.
Well first off if you have the shield under your car then you
will have to remove that, 2 screws under the car, 2 screws and 1
popout clip in the front passenger side wheel well(you have to
remove the wheel to get to it). Once you have that off you will be
able to see the alternator from under the car. Start at the top
under the hood, remove your plastic piece that covers the front of
your engine bay, once that is off unplug the connectors to the
alternator(one is visible and the other is under a black cap you
have to pop off and unscrew), there is also a clip holding the wire
to the alternator on the shield piece of it(pointing toward the
engine, you will see it, it pops out with a bit of force). Once all
connections have been removed you will have to slip your alternator
belt off the alternator(if replacing belt as well, which I do
recomment you just loosen the tensioner and pull it off of all the
pullies) then there is 1 bolt holding the alternator in at the top
(tough to get to but what I did was stick my arm down the side with
a 10mm and wrap it around in front of the alternator and take it
off. Once that is removed go back under the car and there is 1 bolt
holding it in that you have to remove before it comes out freely.
After that your home free :)
look into getting a Hayes repair manual or similar book for your
cars make, model and year. It should tell you how to install the
alternator. Your local library may also have a general auto repair
manual to give you a general idea. Hope this helps :) also if you
have a friend or a friend of a friend that is a mechanic, maybe
they can help
I can give you general information on changing an alternator
because I've done it twice on my 1991 Chevy Cavalier. Before you
get dirty and take your car apart, test it to make sure the
alternator is really bad. If you have a voltmeter, measure the
voltage at the battery with the engine off. For a fully charged
battery, it should be 12.6 volts or higher. Start the engine and
check voltage again, now it should be 13.5 to 14.5 volts,
indicating that the alternator is charging. Auto parts stores can
also test the battery and alternator both on and off the car. First
of all, to avoid any short circuits, disconnect the negative
battery cable before working on any part of the electrical system.
I once forgot to do this while working on my car. The alternator
wire brushed against the mounting bracket and made some pretty good
fireworks under the hood. SAFETY FIRST!!! Once the electricity is
off, take off the drive belt. If your car uses regular V-belts,
there will be a curved metal arm above the alternator. Loosen this
bolt so you can move the alternator to take the tension off. Note:
You might as well replace the belt too if it's in bad shape. If
your car has a serpentine belt (one belt drives everything) there
is a spring-loaded tensioner wheel. Most auto parts places sell a
special tool for releasing the tension. If there is enough room,
vise grips will work as well for serpentine belts. Once the belt is
off, disconnect the electrical wiring from the back of the
alternator. There will usually be a connector plug that snaps in as
well as the "battery" wire, a red wire secured to a post on the
back marked "B+". Once the wiring is disconnected, remove the
mounting bolts that hold the alternator on (usually two or three
bolts), and remove the alternator from the mounting bracket (Don't
lose the bolts!!!). Save the old alternator, odds are you will need
it to return as a core to get your core fee back when you buy the
new alternator. When you buy the new alternator, you will need to
tell the parts guy what make, year, model, and motor size when you
buy the replacement unit. Installation is simply a reverse of
on some late 80's Honda's you have to remove the splash pan and the
left side cv axle to get it out.
Read Me First!!!! I have just completed the changind of an
alternator on a 1987 Honda Accord. I did NOT remove the front left
axel! That is the good news. The bad news is i did some grinding
around one of the engine mounts(harmless, I assure you) The car was
designed where is you have to remove the axil, but let me tell you,
i explored that possibility and from what i read, i tried my way
and it actually did work. If you have gotten to this point 1) Car
is jacked up and you have located and loosened the alternator (if
you are this far, you see what i mean) Its not coming out nomatter
how you turn it, pull it.. i tried it all...believe me, its not
happening.... If your this far...go get you a grinder and grind on
the mount for a while. It will come out and it beats removing the
axil and whatever goes along with that ie..grease spillage or ? If
you know what you are doing than go ahead, odds are you are not
reading this page anyway, but if your like me than take my
advice..GRIND IT! ,,,It works
Check out Autozones website. They have the Chifton manuels for
most cars on the site. It will point you in the right
before you remove your alternator, try this; turn your car on, open
the hood, disconnect a battery terminal; if the alternator is
working fine, the car should keep on running, if the car turns off,
then you know you should change the alternator, I tell you this
because I changed the alternator twice before I found the problem
on my car. << - (Don't try that because unhooking the battery
while the car's running can fry the electrical system.
This is a very involved procedure, that is too complex to post
here. Go to any auto parts store and purchase a repair manual for
you ride. There you will find detailed instructions. Cost around
Disconnect the negative terminal from the battery. Disconnect the
alternator's feed and secure it as to not make contact with
anything. Unbolt the alt. and replace it (belt may be difficult to
put back on...don't use a screwdriver though...could cause damage
to the belt). Check the belt tension as per recommended tension.
Reconnect alt's. feed and, then, the battery's negative.
Chilton's Guide is always a helpful knowledge base for auto
You should only have to take out 2 bolts and take off a belt. When
replacing an alternator you usually want to replace the belt to.
It depends in large part on what kind of car you have.
On most American cars, the alternator's on top--you unhook the
battery, remove two bolts and the belt, disconnect the wires, take
out the old alternator and put in a new one, then reconnect
everything you disconnected. The other end of the spectrum is the
four-cylinder Honda engine, where the alternator is behind the
engine and you need to be a contortionist to get it out.
This works for any rear-wheel-drive car, SAAB 900s, or any
front-wheel-drive with the alternator in front of the engine.
Basically, anything but an aircooled Volkswagen or a four-cylinder
Honda (This works on six-cylinder Hondas too.)
Prop up the hood. Unhook the battery.
There are two bolts holding it in: the pivot bolt underneath,
and the adjuster bolt on top. The adjuster bolt's the one sliding
in the channel. There is also at least one electrical connection.
Unhook all four of those. Remove the alternator belt from the car
and take both to the auto parts store with the year and make of
your car. Buy a new one of each. (Alternators come with a "core
charge"--they rebuild them, and the core charge is to ensure you
bring the old one back. But if you bring the old one in with you,
there isn't a core charge.)
Go home with the new ones. Put it in its proper place in the car
and install the two bolts, electrical connections and the belt. Get
a big prybar and use that to pull on the alternator so it tightens
the belt (when the belt is tight, you should be able to push it
down no more than a quarter-inch in the middle with gentle pressure
from your thumb) before tightening the adjuster bolt.
Hook up the battery and you're done.
If you carry enough tools with you, you can usually replace one
of these in the auto parts store's parking lot. It takes about ten
