I replaced my serpentine belt, but recently it sqeeks again, just a few sqeeks and only when i start the engine. Thoughts?

You might've wanted to replace the tensioner when you replaced the belt (if you didn't).

See this post for how to diagnose a belt noise

Try tightening it first if still doing it a new tensioner may be needed

And WHY do you think the BELT is responsible for the noise? Maybe you should check the accessories and pulleys that are driven by the belt.

Did you spin all the pulleys to see if any felt dry or gritty?
Does the belt have a spring loaded tensioner or did you have to adjust the tension?Source(s): Mitsubishi Master Tech

Friend by the time you have to replace your serpentine belt the tensioner has worn out the tensioner usually only cost about $35 and there's only two or three bolt at the most to replace the tensioner if you replaced your serpentine belt and didn't replace the tensioner the belt that you put in will just wear out and slip. Replace the tensioner it's fairly easy.

Sounds like the issue is that you have squeaking serpentine belt.

likely a pulley...........

If the new belt is making noise and you're sure you or whoever installed it installed it correctly, it's possible the old belt wasn't the cause of the noise but rather a symptom of another part that needs attention in the system. I'd suggest pulling the new belt off and checking the condition of all the pulleys at this point. Not just the accessory pulleys but also the tensioner and idler pulleys as well. One of them may be dragging and causing the belt to skip across (making noise) rather than rolling across smoothly. Good luck.

Check the tension.
Some squeaking on startup, that goes away quickly, suggests that it might be slightly loose.
(But it could also indicate that there's something wrong with a belt-driven accessory, which is putting extra drag on the belt. Why did you replace it in the first place?)
