Well, I answered this one myself. The tensioner pulley is not a standard spring loaded tension, it is a manual tension. To loosen the tensioner pulley, you have to loosen the bolt that adjusts the pulley. *THIS IS NOT THE BOLT ON THE PULLEY ITSELF* If you lay on your back next to the front passenger side tire, head toward the rear of the car, look just past the side of the tire to the tensioner pulley itself (it sits just in front of the a/c compressor). Now imagine a line from the center of the pulley to about 2-2.5" behind(toward the engine) the pulley. Now look just below where that line would end, there should be a 12mm bolt head pointing downward sitting about .25" away from the bracket. This is what adjusts the pulley up and down. To lower the pulley(loosen), just use a 12mm wrench(you shouldn't need much force) and lefty-loosy, righty-tighty applies here (rotate counter-clockwise to loosen). It will take quite a few turns to lower it enough to pull the belt off, but that should be it. If not the pulley itself does come off if you have to, however, I do not recommend removing it if you don't have to (it's a b!tch to put back on with a belt there-I know from experience, trust me) it's just a 14mm socket and watch out for the parts to fall, ie: nut, large washer, pulley, large washer, spacer (have fun putting all of them back on with one hand and a belt there!). Ok, the belt comes off, the new belt goes on, with a little work, then tighten the tensioner back up, (righty-tighty, but be careful to not over tighten or you could strip the tension bolt). Now have fun putting that Power Steering pump belt back on if it's a new one!
put a wrench on the tensioner pully and pull it to release tension on the belt
There is a spring-loaded tensioner that you must move with a ratchet to relieve the belt tension. Before you do, look at the tensioner and verify that it isn't falling apart. If it is falling apart, replace it.
Relieve the tension by putting a wrench on the tensioner and then remove the belt. www.trailvoy.com all the answers for your Trailblazer from true enthusiasts!
Should be a square hole either 3/8" or 1/2" place a breaker bar in this hole and push or pull to relieve tension on belt tensioner to remove belt
what's the question? how to do it? specific to corolla or just serpentine belt in general? release tension on belt by: -put a socket/breaker bar or ratched on the tensioner pulley bolt and use it to relieve tension on the belt -slide belt off tensioner pulley. replace with new belt in same pattern across all pulleys and again relieve tension on the tensioner puller to slide the new belt back on --you may need to remove the bolt on the tensioner closest to the pulley (i don't know just judging by the picture i found) ---if you don't know what the tensioner looks like look up the part on autozone's website for a picture you can match on your car
On the main drive serpentine belt, there is a tensioner pulle. it is positioned at 6:00. relieve tension remove belt. reverse process for reinstallation.
on the tensioner by the front pulley there is a square looking part that can be pushed up or down by using a 3/4 or 7/8 wrench
If it is not serpentine - loosen the alternator mounting bolts and it should pivot allowing you to remove and replace If serpenting - relieve pressure on the tensioner and belt should be able to be removed
Dayco.com offers a free online comprehensive serpentine belt reference tool - including routing diagrams and tensioner information.See "Related Links" belowInstallation NotesPut a wrench on the (spring loaded) tensioner/idler pulley and take out the tension. You can then remove the belt. Replace the belt by fitting it around the pulleys and lastly loosening the tension with the tensioner/idler pulley to allow the belt to fit over the last pulley.Attach a 15mm socket or wrench to the bolt attaching the tensioner pulley.On all 3.0L (OHV) engines, rotate the drive belt tensioner clockwise to relieve belt tension and slide the belt off the pulleys.On 3.0L (DOHC) engines, rotate the tensioner counterclockwise to relieve belt tension and slide the belt off the pulleys.
If your belt is mounted on the passenger side of the engine, attach a socket and breaker bar to the tensioner pulley bolt and pull the breaker bar towards the front of the vehicle to relieve tension and remove the belt.
There should be a tensioner pulley you put a wrench on it and twist and it will relieve tension on the belt making the old one slide right off thenn put the new one on
Yes you need a wrench to loosen the tensioner and then release the belt slowly from the bolt in the top of alternator after that you would need a long and strong screwdriver (crowbar) to release it from the pulley it self. Do not forget to draw the diagram of how the belt serpentine around the pulley.
The serpentine belt on a 406 has an automatic tensioner you need a long ring spanner to relieve the tension to be able to replace the belt. from memory ( don't quote me ) I think it's 15mm.
If it's like my 93 S10 Blazer, then you use a wrench or 3/8 ratchet fitting to release the tensioner.
You can relieve the tension on your 1994 Mitsubishi Gallant belt by loosening the tensioner pulley. The tensioner pulley can be loosened by turning the retaining bolt to the left.
Relieve Serpentine Belt Tension. Before removing the belt, note its routing around all applicable pulleys for ease of installation. # Using a box end wrench on the tensioner pulley center bolt, rotate the tensioner assembly clockwise. # While holding the tensioner in this position, remove the alternator drive belt from one or two of the applicable pulleys.Use a box end wrench to rotate the tensioner pulley assembly clockwise to relieve serpentine belt tension# Slowly release the tensioner, and remove the box end wrench from the center bolt. # Remove the alternator drive belt from the remaining applicable pulleys. To install: When installing the drive belt on the pulleys, ensure that it is properly seated in all of the pulley grooves. # Using the box end wrench, rotate the tensioner clockwise again, then position the drive belt on all of the pulleys. # Slowly release the tensioner until it eliminates all drive belt slack. # Inspect the tensioner indicator to be sure that the belt is properly tensioned. If the belt tension is incorrect, the belt should be replaced with a new one, or, if installing a new belt, the belt may not be the correct belt for your vehicle. # Then start the engine. Ensure that the drive belt works properly. # Stop the engine, then double-check to ensure that the belt is properly seated on all applicable pulleys.
if you cant find a routing diagram for the serpentine belt under the hood take a cell phone picture of it so you know how to route it once its off. Usually you can use a 15mm socket or wrench and relieve the pressure of the tensioner by putting the wrench on the bolt that is at the tensioner wheel and pulling back, to find the tensioner if you don't know what I'm talking about, start the car open the hood and look for something that looks like it is holding the belt tight, usually this tensioner has some slight vibration to it and the wheel is nice and smooth since the back of the belt rests against it, not the grooved side.
pull the tensioner to relieve the tension and slip the belt over the alternator pulley. The tensioner is a spring-loaded pulley below the alternator. The tensioner takes a special tool that fits into a square hole in the side of it. Or you can use an 18 mm socket on the tensioner's pulley bolt. Follow the decal near the right front corner of the engine compartment to route the new belt.
No speacial tool required. Use a standard socket driver I believe its 3/8 but may be 1/2" There is a square punched out of the tensioner to receive it. Applying torque with the socket wrench will relieve tension to allow you to slip the belt off or the new belt on. repair in minutes Cheers
Usually you relieve tension on the tensioner pulley by pulling it to the left or right.
One way is to put a wrench or, better yet, a long handled ratchet (12" or so at least)on the tensioner pulley center bolt and turn it such that the pulley rocks to one side or the other to relieve tension, slide the belt off and release the pulley slowly. Te reinstall the belt, use the same technique.
Most likely you need to look for a grooved pulley that looks like it may not be related to any parts of the engine,(i.e. the water pump pulley, a/c pulley) this is the tensioner pulley. The tensioner pulley on my '97 GMC 5.7L is located just beneath the alternator. Inorder to relieve the pressure from the "tension arm" find a square opening molded into the pulley arm, and insert a breaker bar to use as a lever for relieving the tension. Some vehicles may need a ratchet and socket in order to move the tensioner arm. With a little effort to relieve the pressure, you can now remove the serpentine belt. Most vehicles will have a diagram in the engine compartment showing the specific route for the belt to go on the pulleys. I've found that the easiest way to install the new belt, is put the belt around all of the pulleys first then lastly on the tensioner pulley.
I have a 92 PA and have used a socket and the ratchet handle. With limited movement in this area the ratchet will allow you to get more movement of the pulley to get the belt off. Just remember which way the belt was routed as it can be confusing when trying to put it back on.
the front of the pulley that the belt rides on will have a square hole in it. you should be able to put either a 3/8 or 1/2 inch ratchet in that hole and pull it one way or the other to take the pressure off. the size of the hole and the direction depends on the vehicle.
