Mitsubishi Repair: Mit Galant 01 sqealing, car gas, alternator

Question
Linda,
First I had to change my alternator a month ago.  Then last week I did the tune up.  The dealer replaced coil in order to turn the check engine light off.  Now the car is sqealing badly.  Especially when I give gas while driving.
Do you have any clue?  What should I do to fix this.  Thanks,

Answer
Fred: Take it back to the shop that fixed the alternator, sounds like they did not tighten up the belt right on the car. Or else you need a new belt that runs the alternator. I believe that is what is making the noise than you give the car gas. Hope this helps and God bless: Linda
