Timing belt Where is the tension release pully ?

If it a serpintine belt (meaning one belt runs everything) and it comes off on its own its time for a new belt to install new or reinstall old one . All cars have abelt routing diagram if not google your car and year asking for belt diagram. Locate tensioner usually turns with wrench ( socket or box end is best) route the belt according to dia. leave tensioner for last rotate pully with wrench to get belt over release tension on wrench thats all there is to it. But if belt keeps coming off usually indicates new belt is needed could also need tensioner pully its a good idea to replace both at the same time

They are hard to release on all vehicles. You need to pull and release the tension with a wrench attached to the tensioner and slip the belt off the same time removing & installing it on

To get this off, there are two ways:

1. Loosen the alternator, and pull it back until the tension is released.

2. There will be between the various pully's (belt runs around) a tensioner. This is holds the belt tight. With a rachet and socket, pull (push) the tensioner until the belt has slack - pull one part of the belt off (any pully) and release the tensioner back to it's position. (It will go further than when the belt was on - this is normal.

When installing the new belt, if using the tensioner, the belt will need to be placed on the tensioner last - get the belt around all other pully's in it's correct configuration, then, pull back (push) tensioner *(while holding the belt tight with other hand, and ready to be pushed over tensioner) and slide belt into place over it.

Also note: a serpentine belt will only go on one way (grooved side down).

Below the altenator is a tensioning pully, insert a 3/8" ratchet or breaker bar in the square hole on the tensioner and release the tension on the surpentine belt and remove the belt. Route the new surpentine belt in place up to the altenator and take the tension off the tensioner and put the belt over the altenator pully. Double check to make sure the belt is riding correctly on all the pullies before starting. Crank the engine over several times before starting to seat the belt.

hi from uk the cambelt/timing belt comes as a kit ie timing belt and tensioner cost £50 here in uk ? it is not too difficult diy job approx 2hours the engine must 1st be set to TDC number 1 firing then at this setting the cam cog mark is a hole drilling in the web of cog and should line up at 12 oclock upwards and using a mirror look thro drill hole and you will see a vertical notch/groove behind on font engineface this is correct mark the crank cog mark lines up with aother mark on engine front face at approx 12 30 pm oclock ? if now set you slacken tensioner bolts and push t/pully away to left from belt ? then remove belt next remove complete tensioner assy after undoing bolts then fit new tensioner push t/pully to left from belt run and lock bolt/s recheck t/marks then fit new belt from c/shaft in anticlockwise rotation when fitted release tensioner bolt and allow to tension belt push t/pully onto belt and lock up tensioner bolts20=27 Nm rotate engine manually for four turns then recheck marks ? should still aligne then re assemble torque crank bolt to =140-150 Nm A LITTLE HINT ? b4 you remove the water pump belt ? slacken thefour 10 mm headed bolts (spanner size) that secure w/pump pully to pump it will be easier to halt rotation of pully if you holt belt tight by hand this pully has to come off to remove c/belt covers same for power steer belt which is also driven from the w/pump pully the power steer pump slide adjuster has a 12 mm bolt you slacken and best done with open end spanner ? after slackening the pump mounting bolts/nuts underneath pump hope you can follow this info/tips wish you good luck from uk

Follow the belt around the pully's and look for a pully that is attached to an arm. this is a spring loaded tensioner pully. on this tensioner, you can often fit a 3/8 drive ratchet directly in the back. if so that how you'll be able to release the tension on the belt. otherwise use a socet (if there's enough room) or wrench on the nut in front as if tightening. this will release the tension on the belt.

Hope this helps!

there should be a tension idler that has to be retracted to give the belt slack most has a 1/2 inch square hole in it for a break over bar to fit in it to realese tension however i have not delt with this particular model but most are the same also be sure to carefully look at how the belt pattern is or if it still has the sticker for belt routing on it realese the tension and slip belt off first pully making sure not to put yoru finger between the belt and the pully after the first pully has been cleared the the tensioner can be released and the belt removed then put new belt on all pullys but one at this point tensioner bust be realesed again ultill belt is plased on last pully be suer belt is inline with all pullys

pasenger side of the car ther will be a Tensioner pully (wheel) stick a 3/8" scocket on the wheel ( there is a place for it) and move it to the Right (drivers side) this will slack the belt and allow you to replace it. often there is a diagram that show's you the belt patern, and one of the pullys will have a little arrow that points in. that is the indication of you tensioner pully and the direction it needs to go to release tension. After you have the old off, put the new one on around and release the tensioner pully, and thats is

FOR A 1.9L ENGINE. CANT SEND PIC, START BY PUTTING BELT OVER ALTERNATOR PULLY,THEN TO THE RIGHT OF POWER STEERING PUMP PULLY FROM THERE TO THE LEFT SIDE OF THE IDLER PULLY , THEN UNDER THE A/C COMPR PULLY AND UNDER THE CRANK PULLY RELEASE TENSION ON TENSIONER BELT GOS UNDER TENSIONER.

locate the tensioner... you need a "breaker" bar with a 3/8 inch socket head... a rachet would do with a long enough handle. there is a square hole in the tensioner... you need to release pressure on the tensioner long enough to get the belt on.
