How do I change the belts on a 2002 Toyota Sienna V6?

I was expecting to find a single serpentine belt with an automatic tensioner pulley. I have changed serpentine belts on many models with no problem. But this Sienna has two belts, not one. One belt drives the power steering pump. The second belt drives the alternator and A/C. I don't see a tensioner pulley on either belt. Do these belts work like old-fashioned V-belts belts where you tension them by loosening something (like the alternator) and then using a pry bar to tighten the belt? I can barely see the power steering pump so it looks pretty tight, I welcome advice from anybody who knows this model. Thanks.How do I change the belts on a 2002 Toyota Sienna V6?loosen the 14mm bolt on top of alternator. loosen 12mm bolt below alternator sitting sideways. adjust belt tension with 10mm bolt running through previous 12mm.

loosen 12mm bolt on top of power steering pump. underneath vehicle loosen a 12mm bolt below p/s pump pull on belt to relieve tension, and pry carefully to increase tension.

a bit of advice when reinstalling belts, the belt tension has to be just so, too tight and you will wreck the bearings in both pump and alt., too loose and the belts will squeal they have to be just right.

Change Alternator 1998 GMC Sonoma?

Ok, so my alternator went out last night while helping a friend move.



How hard are these things to change? Is it simply just disconnecting the battery, taking off the belt, disconnecting the ground and positive wire from the alternator itself, removing the bolts and you're good to go? Or what?Change Alternator 1998 GMC Sonoma?Do not disconnect the battery, just make sure the key is off, it could erase the code to the radio and possibly other computer functions. Just release the tension on the belt tensioner enough to get the alt out, reverse to install, it isn't hard but I have seen people remove the tensioner when all you have to do is pull down on the spring loaded nut holding it on the pulley, good luck.Change Alternator 1998 GMC Sonoma?Yep. It's pretty easy.



Just make sure you connect the negative battery cable AFTER you connect the positive.Change Alternator 1998 GMC Sonoma?that about it it just doin itChange Alternator 1998 GMC Sonoma?DO disconnect the battery.

You only need to disconnect the negative battery cable, not both.Change Alternator 1998 GMC Sonoma?Yes you have it down real good just do as you said and you are good to go , Good luck

How do i change the ac belt of a dodge neon 2000 is the same that goes to the power steering and alternator?

The automatic belt tensioner maintains proper tension on the power steering/air conditioning belt. After belt is installed, inspect belt length indicator marks. The indicator mark should be within the minimum belt length and maximum belt length marks. On a new belt, the indicator mark should align approximately with the nominal belt length mark.How do i change the ac belt of a dodge neon 2000 is the same that goes to the power steering and alternator?AS Tracy, but leave 1/2 inch play

On a 1993 grand am,need to change the alternator. do i have to loosen the teshin up to loosen the belt?

how do i lossen the tenshner up?? please explain??On a 1993 grand am,need to change the alternator. do i have to loosen the teshin up to loosen the belt?The tensioner is a spring loaded pulley you have to use a tensioning tool or long breaker bar to take tension off belt, remove from alternator pulley to change alternator. You will be able to pull tensioner pulley off belt and feel more resistance as you release tension from belt. Be careful when releasing tension so you don't jam your fingers between tool and engine brackets.On a 1993 grand am,need to change the alternator. do i have to loosen the teshin up to loosen the belt?there should be a bolt or a spot for a 1\2%26quot; breaker bar on the end, just pull until the tension is off the belt.On a 1993 grand am,need to change the alternator. do i have to loosen the teshin up to loosen the belt?oh yeah, absolutly. That is the only way to take that belt off unless you cut it off, and then you will have to loosen it t put it back on any way. Im not sure if that car has an auto tensioner or not. If not Then you will have to loosen the bolts and pry it so you can loosen the belt. And before you do anything disconnect the battery!!!! Good luck to you.

How do you change a serpentine belt on a 1995 chevy cavalier w/air?

I have replaced the alternator and I have the belt in place but can seem to get the pullies loose enough to put the belt back on.How do you change a serpentine belt on a 1995 chevy cavalier w/air?There should be a a %26quot;spring loaded%26quot; tension pulley on it somewhere. Follow the path of the belt until you find it. Once you locate it you should be able to put a socket or wrench on the pulley and pull it (not turn it) as you do you should see the tension on the belt release. Once it is loose enough slip the old belt off. The precess i the same to put it on except you need to have the new belt correctly around all the other pulleys and when you pull on the tension pulley it helps to have someone slip the belt on for you.

Note: It will take a lot more pull to get the new belt on then it did to get the old one off. The old bet has stretched so you don't have to pull as far.



Hope that helps...How do you change a serpentine belt on a 1995 chevy cavalier w/air?There should be a tensioner somewhere.

You should be able to wedge a crowbar or ratchet in it and pull up on it to releive the tension.



Look for a piece on there that looks like it can swivel.



Good luck!How do you change a serpentine belt on a 1995 chevy cavalier w/air?You have to retract, pull the tension back, on the idle tensioner pulley. Sometimes it takes alot of muscle.

How do i change the alternator on my 98 cavalier z24?

i need to change the alternator i found the bolts to take off but i cant remove the belt how do i do that.How do i change the alternator on my 98 cavalier z24?Find the tensioner on the serpentine belt. This will release pressure off of the belt, allowing you to slip it off the alternator. Also, check for the condition of the belt, as it would be a good time to chnage it while it is loose, as belts usually last less than the components that they wrap on. If this is the original belt, check for cracks or heavy wear to it.How do i change the alternator on my 98 cavalier z24?I have found that removing the throttle body intake manifold and fuel rail really help this project go a lot better

Change drive belt on 1998 Ford Ranger?

I have found the tensioner but need to know how to loosen it in order to remove the belt. There is the large bolt that is in the center of the pulley itself and then there is an inset bolt (smaller) on a piece behind the pulley (that has the belt wrapped around it).



Trying to replace the alternator.



Any information, pics or anything would be VERY helpful.Change drive belt on 1998 Ford Ranger?Look at the arm that the polley is fastened to. You should find a 3/8%26quot; square hole. Put you 3/8%26quot; drive ratchet in this hole and pull in the direction away from the belt. It is spring loaded. While holding tensioner released, slip belt off the alternator pulley, then release the tensioner.Change drive belt on 1998 Ford Ranger?most of them you just use a 3/8 drive ratchet without any socket. you should see a square hole for it to fit in.Change drive belt on 1998 Ford Ranger?DON'T LOOSEN THE MAIN BELT IDLER or TENSIONER!!!!!!



Disconnect the negative bat. terminal.

At the alternator.

Push both little tabs on the molex connectors and disconnect them both.

Loosen the alternator pivot bolts and loosten the adjustment arm bolts.

Pivot the alternator up to remove tension on the belt.

Remove the belt from the alternator.

Disconnect the pinch and pivot bolts and remove the alternator.

Installation is reversed.

You must adjust the tension on the belt with a drivebelt tension gauge. Some will say you don't but it's a sepinteen belt and must be tensioned correctly
