1999 Buick Century has a slipped crank pulley. How do I re-align it? When my serpentine belt broke I noticed the pulley had slipped over about an inch on the hub. Is there way to adjust it back to th

Easy job on those vehicles. Usually need a wrench that fits over the belt tensioner, and you raise or lower it, taking tension off the belt. then just slip it off the nearest pulley-often the alternator pulley. Now you can let go of the tensioner and remove belt. Notice how it is fit. There should be a diagram on a sticker of how the belt fits on.

Maybe one of your pulleys, is frozen check ac, power steering, alternator, ect

Look at the pulleys with the belt off. Are they aligned? If so then one of the pulleys is bad. This would cause a belt to come off tract. If the balancer is out, check the bolt, tighten it back to where the balancer is back in line with the rest.

Make sure that the belt is fully seated in ALL pulleys, if it still slips off, then you have a pully that is bent, or out of alignment.

Hello, guys. I only found a article about how to replace water pump on a 2011 Buick century. Hope it can help you.

Also, there are lots of OBD2 diagnostic technical service for your refer.

You need to replace the harmonic balancer it is coming apart.the outer part of crank pulley is actually rubber mounted to the inner part.

Hi,

The tools required are:
1/2-inch drive ratchet
2 - 1/2-inch drive 8-inch extensions
1/2-inch drive socket set

Please follow these steps to replace the serpentine belt on your 1999 Chrysler 300M:

1. Open the hood and prop it in place.

2. Locate the serpentine belt adjustable idler pulley on the front of the engine. This adjustable idler pulley will be closest to the top of the engine. Position a metric socket onto the ratchet and loosen the bolt in the center of the serpentine belt idler pulley.

3. Now please loosen the push bolt on the side of the idler pulley. It is a 15mm size and the push bolt on the side of the tensioner is 13mm. Pull off the old belt.

4. Loosen the tensioner pulley for the AC belt. The same steps need to be followed for this as well.

5. Next slip the AC belt on the back of the crank pulley and route it as per the diagram under the hood.

6. Now you need to tighten up the idler pully and the push bolt until the belt play is within factory specifications, then tighten the hub bolt in the center of the pulley as well.

7. The same thing needs to be done for the serpentine belt as well. Just ensure that you tighten up the bolts and have the specified play in the belt. Check the belt tension by pushing inward on the belt.

8. Crank the vehicle for about 15-20 seconds. Then turn it off and again check the tension in the belt. Adjust as necessary. You need to have about half an inch of play in the belt.

If this doesn't work for you or in case you need any further assistance, please comment and let me know, and I will be happy to assist you to further resolve your issue.

I will appreciate your feedback and positive rating for this solution.
Thank you.

This SHOULD be how it's done, but not so on the 90's Park Aves.
With this 3.8 L V-6, you have to remove the motor mount on the side of the engine--and without the proper tools it's about a $290 job for the dealer.

you could adjust your tensioner to fix it, but most likely your power steering pumps pulley is not completely parallel with the the crank pulley
