How do you replace alternator belt on 1998 Honda Civic?
The alternator belt on a 1998 Honda Civic is replaced by loosening the mounting bracket, disconnecting the wiring harness, and slipping the belt off the pulley. The alternator is then unbolted, removed, and a new unit put in place.
How do you replace alternator on Renault kangoo?
Remove top engine mount n use a jack
To remove the alternator on kangoo, u should undo 3 bolts(13mm) n disconnet 2 wires.

How do you replace the alternator on a 2000 VW Jetta VR6?
It's a real pain. It can be done though. I recommend you have a service manual handy, at least to get the torque specifications.
The Bentley manual would have you take the bumper cover off, then remove the radiator support and swing the radiator, ac condenser, bumper structure all off to the side. That seems like a lot of work, but might allow direct access to the alternator.
You can however get the alternator out from below (not above, the intake manifold will be in your way). These steps are from memory and will not apply to the 4 cylinder models.
First get the car in the air, either jackstands or ramps. Now that the car is in the air you must remove all the splash shields from under the motor.
REMOVE THE NEGATIVE CABLE FROM THE BATTERY TERMINAL...or both if you like. The last thing you need is some sparking while you're working or to ruin your new alternator.
Remove the cover from the side of the engine (skinny one that covers the belt, you don't need to remove the larger one holding the spark plug wires).
Remove the serpentine belt. (Is it time for a new one?) This is done by putting a M8x1.25 bolt in the top of the tensioner to release the tension. Only drive the bolt in enough to remove the belt. I prefer not to keep the spring under compression so let the bolt out afterwards, might as well leave it in part way though. Now remove the tensioner (blocks a bolt for the alternator. 3 bolts, 13mm, one super hard to get at.
Now it's time to go under the car again, remove the power steering pump and the AC Compressor. Remove the power connector(s) on the AC Compressor Clutch first. The P/S pump is pretty light, but you might want something to support the AC Compressor.
You can now get to the alternator, remove the electrical connections first, now the bolts. Some bolts might be easier from above. By this time you might want an assistant. After the bolts are out you'll be wondering why it didn't fall on your face, yeah...it'll take some work, and it's going to be a tight fit.
Now compare your old alternator to the new one...make sure the pully on your new alternator is correct (7 spline belt, not 6 like the 4cyl cars). Mine was incorrect and I had to move the pully, requiring a 12pt driver set to hold the spindal. You don't want to install the alternator more than once if you don't have to, so check now.
--BREAK TIME-- drink a beer, get one for your friend that agreed to help too.
Okay...you're half done and it will go a little faster now because there's going to be a little less fighting with stuff. Now, back under the car!
Alternator goes back in, connect the cables.
AC goes back in, connect the cables.
P/S Pump goes back in.
Put the tensioner back in, don't over torque, it mounts to the head, and it's aluminum, you can strip it out without realizing if you're not careful (ask me how I know).
Tighten that bolt back into the tensioner (you left it in so it didn't roll away right?) Install the serpentine belt (don't remember the path? shame on you, search the internet or figure it out, it's not hard). Remove the bolt, put it in your tool box for next time.
Reconnect the battery. Start the car. Battery light should go out, lights aren't flickering? If so it looks like you succeeded, congratulations! Turn off the car.
Put all the splash shields back on underneath and the engine covers on top.
Lower the car. Clean the garage. Drink more beer or go driving...
If the battery is sulfated (or otherwise faulty) to such an extent that it calls for a continuous charge, the alternator never gets a chance to switch off. With the resposibilitiy to run continuously the alternator overheats and eventually fails. Never replace a faulty alternator without also checking the battery.
What tool is required to release the belt on a 1998 Ford F-150 V6 and how do you adjust the tension?
its easy the tensioner is on the left side middle facing the vehicle, If i remember correct it is a 5/8ths and all that you need is a regular ratchet. If you look at the digram on the vehicle it displays the belt route. The whole process is really easy! it auto ajusts the tension if you need and new assembly they sell it at autozone.
The above answer is correct, except that usually there is a 3/8 square hole on the tensioner and it can be released with any 3/8 drive ratchet.
Where can you find an alternator belt diagram for a 90 Geo Prizm Hatchback?
Try your local autozone. They should be able to give you a print out. If that fails, try looking in a Haynes repair manual.
How do you replace the alternator on a 1996 Isuzu Rodeo?
There is one long bolt on top. One smaller bolt on the bottom. They should be pretty easy to see. When installing the new one, align the top bolt first. The bottom bolt will be a little trickier since the alternator is used as the belt tensioner. A long screwdriver and an extra set of hands really help.
How do you replace the alternator on a Hyundai Sonata 4 cylinder?
1. Remove the passenger side front wheel. 2. Remove the plastic splash shield for access to the alternator 3. Remove the top engine plastic cover 4. Disconnect the battery 5. Loosen the water pump pulley bolts (4X10mm) 6. Remove the belt 7. Remove the alternator (2 bolts and 2 electrical connections) 8. Remove the water pump pulley for access to loosen the fastening bolt of the bracket of the alternator. 9. Loosen the second inner bolt of the bracket, but do not remove it. 10. Remove the two bolts that holds the plastic piece that is on top of the engine which is in parallel to the line of the sparks plugs and remove the plastic piece just enough to get space to take out the alternator. 11. Move the alternator bracket downward for enough space to take out the alternator. 12. Loosen the bolts that hold the electrical junctions to the body for enough space to take out the alternator. 13. Take out the alternator from the top.
How do you know if you have a bad alternator or car battery?
One should start by measuring the voltage of the battery with the engine off. If you measure a low voltage then it is pretty easy to understand that this will not start the car. At this point, you could charge the battery, remove the battery and have it tested (which is free at a car parts store) and if necessary replace it by a good one.
<><><>
Your car's volt gauge should read about 13.5 to 16 volts with the engine running. It should read 12 volts with the engine off. You mentioned the old battery had a lot of corrosion on the cable connections. Corrosion can cause a voltage drop to the starter, causing it to turn the engine over slowly or not at all. Auto parts stores have testers for batteries.
These simulate the load of the starter on the battery and measure whether the battery has enough juice in it. The machine can also test the alternator while it's on the car to determine if it is charging when the engine is running.
Also there is a quick and dirty test you can do with a multimeter (Note: these are pretty inexpensive and are very useful in other DIY projects involving any electricity.) . Set it to the "Volts DC" scale. With the engine running, touch the red probe of the meter to the positive "+" post and touch the black probe to the negative "-" post of the battery. It should read 13.5 to 16 volts. If it is less, the alternator may not be charging.
<><><>
One should never disconnect either battery cable with the vehicle running/on, as it could cause an explosion, leakage, or serious electrical damage to vehicle.
<><><>
You need to hook it up to a battery charger for several hours at 3 or 5 amp slow charge- then bring it to a battery store or maybe a kragen or pep boys auto store and they load test it for free.

How old the battery is generally your first clue. Most only last about 5 years. Second, are you in hot or cold climate? Cold weather drains a battery so the cold cranking amps on it have to be high enough to allow cranking of the battery in really cold wheather.
Age of the battery can reduce the power of the amps needed. Heat in really hot climate can also kill a battery over the years. If you can take it to a auto parts store they can put it on a machine to check to see if the battery is fully dead or is still good. If it is still good and just has a low charge, they can fully recharge it. If it is still in the car and you want to check it without going to the store, try to crank the car. If it drags a little and you are not in a cold climate it just may just need a boost (If in a cold winter climate it probably needs recharging).
You can boost with another car and cables or buy the instant boost sets they have out now (no other car needed and they work great). If it cranks with a loud turnover noise and the car just doesn't start it could be another problem. You also need to remember that the alternator is the equipment that charges your battery. If your alternator is bad the battery will just drain like a flashlight battery until it is dead. The alternator keeps your battery recharged as your car uses it while the engine is running. Just hope its the battery because an alternator is much more expensive.

Does the crankshaft pulley operates belts to turn the alternator and water pump?
Usually, the answer is yes. the crankshaft pulley drives belts which in turn drive auxiliary devices such as alternators, generators, water pumps, smog pumps, power steering pumps, A/C compressors, etc.
There are a few occasional exceptions where some auxiliaries are driven by gears connected to gears within the engine. Some of these instances include the engines in heavy construction equipment, agricultural tractors, and large truck tractors.

Why does your car keep blowing alternators?
Can be because of a bad battery, or overloading the charging system with extra accessories (like aftermarket stereos), or jump starting either that car or other cars with that car. If none of the above there may be a short or other electrical problem. Sometimes vehicles just have bad designed alternators that don't live long, or the rebuilders don't replace enough of the components to successfully give you a good part. Try a new not rebuilt part if you can and see if that doesn't work better.
