I have installed the new alternator with the new pulleys as well as the belts ! However, when i first started the car the squeaking sound was LOUD ! Do you think guys it's from the torque that i have not get it right or the alignment was wrong ! any thoughts ?

I have never used factory specs when torquing. It might be wrong but after 15 years I have never had a problem. Squeaking usually comes from either a bad belt alignment or needing to be tightened/loosened depending on what type of tensioner you have. I think these are auto adjusting could be wrong so it would have been the alignment or lack of having a v ridge belt which makes things easier for me. Not by any means am I a mechanic but I have formulated my own conclusions on certain situations which have worked for me.

I have done the right alignment with the dealer and they've checked everything and told me it was over tighten a bit ,however, they fixed it and everything looks okay.

After the change of the alternator, I have still one problem that is driving me crazy and I wish to solve it! Which is linked in this link !
The issue not the rpm but it's when I turn the car completely off and try to crank it again (especially when it's hot) it won't start easily as you will see in the video ! Did any one have this issue somehow?

Is this a car you just bought recently? You have a lot of issues going on at one time.

It seems like your starter is going out. You can either rebuild it yourself or buy a reman. It seems like the starter is staying engaged after releasing the key.

No it's not a new. I have had it for 3 years now. The rpm craziness is because i have installed the new MAF it will act like that but if i swap it with the old one it stays normal. However, the main issue is the start thing ! I hope it's what you mentioned because i am not sure what it is !

If it is the MAF making it jump then the new one might be bad. Is the new one OE or aftermarket/OEM. If its aftermarket/OEM then get you an OE. That should correct it. If it is indeed and OE then you might have been sent a bad one or the wrong one.
