1999 Saturn SC2

First of all thank u so much for ur donation it really helps so we can keep answering peoples car questions. The pulley is suppose to spin u can change just the pulley I belive they sell a replacement one at the auto parts store. But if it doesn't have a strong spring return u will have to replace the whole thing. Take a wrench out put it on the bolt and push down if it doesnt have a strong spring return u will have to replace the whole thing. Let me know what u find.

Well ben theres nothing in my bag of tricks on this one but ur right theres only two bolts holding it there 10mm. The best way to replace it is turn the wheel all way to the right. Then remove the foward splash shield closest to the front of the car. Then u will need a floor jack get a small piece of 2"x4" and put that between the floor jack and the pan. Jack the jack up till in touchs the oil pan firmly. Then take out the 5 15mm nuts off the upper engine mount. Now take the mount out u may have to jack the motor up more. Now jack the motor up and remove the top bolt from the tensionar now lower the engine all the way down. Remove the bottom bolt and the tensionar put the new tensionar in start the bottom bolt by hand dont tighten it. Raise the engine up and start the top bolt by hand now tighten it up. Lower the engine back down tighten up the bottom bolt. Now raise up the engine back up route the belt around all the pulleys even the tensionar except the alternator. Now get a wrench and push the tenisionar down put the belt on the alternator. Reinstall the upper mount and the side splash panel.I would go with the new tensinar good luck let me know how it goes.

Yeah I know my saturns had over 16yrs practice at the Saturn dealer I was trained by the factory in spring hill Tennessee. Glad to hear u got it replaced ok that's the way I do it and I can do it in like 10-15mins.I want to thank u for thanking me most people just take the info and run when they fix there car.U have a great day and thanks again for the donation.
