Nissan Repair: squealing noise, squeal, pulleys

Question
I have a squealing noise in my 2000 xterra. Today I had a tune up. All belts changed etc. Still making the noise. Any suggestions?

Answer
Cathy,

If it is belt squeal have them re-tighten the belts.  If there is squealing and the belts are tight you are going to have to look at the alternator, airconditioning or power steering pulleys as sources of the noise.  That is, if one binds up it does not matter how tight the belts are as the noise will be there until the particular item locks up.
