Want this question answered?
If this Pontiac Tempest is the same car as a Chevy Corsica, and it has a v-6, it should be automaticly tightened. If it wont tighten, you might check to see if it has the right belt, If it is the right belt, it could be the automatic belt tensioner.
the clutch fan is easy to remove and replace. you will see it on the upper most pully(water pump). just four 10mm nuts to take off. however the pully likes to spin so i use a screwdriver to hold it still or you could tighten the belt so it wont spin, just remember to loosen the belt back to where it is supposed to be once you are done.
loosin the nut on the in side on the trunk adjust it where you wont it then tighten it back
No the crank does not have a thread as long asyou have taken out the bolt in the center of the pully it should move they can be very tight. try tapping round the edge of the pully as you apply pressure with the puller
In addition to moving the tensioner pulley, you might have to loosen the alternator to gain a little more slack space.
I have run into this twice before,and it DOEShappen. There is not much you can do because there is no adjustment or way to shim this item. But look at the alignment of the belt on the pully and all pullys to be sure it's the alt. causing this squeal. You should return it to the store for replacement and dont let them tell you "it's the tensioner" or "the belt is worn out". I have replaced both of those and still no change. The pully is probably on too far. If they wont trade out with you, ask for your money back and a core alt. so you can go somewhere and get a good part, or, you can try to shim the pully by making a shim from some thin metal or grinding a washer to thin it down,but there is no guarantee that this will work or for how long. The parts store has you over a barrel and keep going back until they get it right. Good luck.....
Pull it out and fit a new one
sounds like your pully tensioner might be bad, throwing the belt... which runs your alternator, which might be why the car wont start.
yes you do have to loosen the nut on the tensioner, or else u wont have ennough slack in the belt to put it on, once it is in place then make shure u tighten the bolt again
on the cam there is a little dot that is machined in the cam gear. make sure that it is at top dead center( remember that the motor sits at a slight angle so it wont look like the very top by looking strait at it. you will have to take the crank pully off to see the mark on the crank gear. the mark is an indentation on the back of the pully. line that up with the little arrow next to the gear. after that is set put the belt on making sure that you don't move the gears. put your pully back on and use a timing light to set the timing at two degrees top side by looking at the marks on the timing belt cover next to the crank pully.
If you do that the trucks wont turn, wheels wont rotate, and the board will get stress fractions from the nuts being to tight so you probably wont be going anywhere
