What causes cold squeel until warmup? on 2003 Kia Sedona

Sedona 03 3.5 tension pully area makes squeels on initial start up until warmed up. Belts and 2 tention pulleys were changed out but the squeel came back a week later, I'm out $226. with same problem back! 86k miles. Mechanic told me that 3 bolts were missing from timing chain housing. I bougt van with 63k mi. Perhaps the timing chain was replaced prior to purchase. Can you give some info?

could be a bad belt or a tensioner
Exactly, some parts just don't cut it but everyone wants the best price. I remember when
a part from say NAPA was as good as you could get. But with auto part stores popping up
on every corner, everyone has a second line just to compet. What a shame!
SOME THINGS TO LOOK FOR: BELT TENSION(IS ADJUSTABLE) NEEDS RETENSIONING, BETTER GRADE BELTS, FLUID LEAKING ONTO BELT
MISALIGNMENT OF DRIVEN COMPONETS. TAKE IT BACK TO INSTALLER AND ASK TO HAVE IT RECHECKED. ALSO CHECK PRODUCTION DATE TO MAKE SURE BELTS ARE CORRECT!!!!! MAY HAVE CHOICES! FROM A CERTAIN DATE/ TO A CERTAIN DATE. IF THIS DOESEN'T SOLVE THE PROBLEM THEN I DON'T KNOW OF ANY THING ELSE. YOU HAVE A TIMING BELT NOT A CHAIN.
