Ok so I just searched alot but I'm still kinda confused here.

anyways, I got my timing belt\water pump changed recently, and now my engine idles really low (like 300rpm) and only at idle and when the car is warmed up it makes a high pitch squeaking noise, but when I give a bit of gas it goes away.

I'm thinking that my alternator belt is loose, since this only started right after I got the timing belt changed. My idle was fine before and there was no squeaking.

Also, how do you tighten the alt belt? Loosen the alternator and move it?


Thanks.

 

Bleed the coolant system and check for vacum leaks .......good luck
