These belt/tensioner questions sure come up a lot! I can't tell you exactly where the tensioner is on your car, but it's usually easy to find. It will probably be the only thing that looks like a pulley that has a smooth, polished finish. On my '96 2.2L, it's located to the rear, and slightly down from, the alternator. It's been suggested here, that if you push on the belt (I'd guess wherever there is a long run between pulleys) you can see the tensioner deflect. I haven't tried that yet. I hope this helps a little! FriPilot
If your car has a serpentine belt it will have a tensioner pulley. A tensioner pulley is easy to spot. All of your bolt on accessories i.e. water pump, alternator, a/c compressor etc. will have a pulley to run each one. There will be 2 other types of pulleys, a idler pulley and a tensioner. The idler pulley will be a single stationary pulley with a bolt going through the middle and the tensioner pulley will be on a spring loaded piviot.
it's in the belt path and has sort of a snout behind the pulley. It's back near the tensioner.
The tensioner rotates or swivels on it's mount to put some slack in the belt. You can usually get a wrench or a shallow socket on the nut that holds the pulley and rotate it whichever direction it needs. FriPilot
In addition to moving the tensioner pulley, you might have to loosen the alternator to gain a little more slack space.
tension pulley is an automatic tensioner that keeps the serpentine belt at the proper tension it is a single pulley that is smooth (no grooves) usually turning clockwise with constant pressure loosens pulley for belt removal use caution pulley is spring loaded
Usually right above and in line with the crankshaft pulley
Tensioner PulleyThe Tensioner Pulley on the 1997 Pontiac Sunfire 2.2L. The tensioner is located just behind the alternator, if you are looking straight at the front of the car. It is the top middle pulley. To release tension you must purchase a special tensioner wrench to turn it. There is a nut that resides on the recesses of the middle of the pulley, and if you try to use a socket and wrench or an open end wrench, you will find it rather hard because there isn't enough clearance to get your wrench or socket in there. The other alternative is using a crow bar to push the tensioner forward. But you risk scratching up your pulley. It is also harder to get your belt back on the pulley, when you use a crow bar. But it can be done........................................ I MUST MODIFY THIS ANSWER I DIDNOT ANSWER THIDS BUT JUST DID THIS YESTERDAY YOU CAN USE A OPEN END WRENCH ITS A TIGHT FIT BUT IF YOU PUT THE BELT ON THE ALTERNATOR PULLY LAST USE A FLAT SCREWDRIVER TO HELP EASE IT ON. NO NEED TO BUY THIS TOOL .PDP
It is the same assembly as the tensioner pulley - the little pulley that isn't attached to anything.
I guess you're referring to the tensioner. It seems to be in different places on different engines. In my '96, it's down and rearward from the alternator. It's pretty easy to identify. It's surface is very shiny and has no flange, if memory serves. It's probably the only pulley-like device which contacts the back or outside of the belt.
Answerwater pump for a 98 sunfire is located with the timing belt can be a job. have to remove front of motor. enj. mount ect. More: Unless the 98 is much different from my 96, the water pump has nothing to do with the timing belt. Also, there is no need to remove an engine mount bolt.You should be able to loosen the belt tensioner enough to get the belt on and off the pump pulley.
I believe it to be on the fan belt mechanisim..the pulley that allows you to adjust the tension.
To change the serpentine belt on a 2003 Pontiac Bonneville, loosen the tensioner pulley and remove the old belt. The tensioner pulley is the wheel in the belt system that has a bolt through the middle in a slot that can be adjusted. Put the new belt on and tighten up the pulley.
