Did you replace the tensioner ASSEMBLY or just the pulley as stated? .. Which engine is under hood??

Have had good luck using the next shorter length belt.. However we stock belts @ the shop so it's no problem for me to do that... Also have better luck with Goodyear Gatorback belts to solve belt noise. .. Hard to tell by eye if ALL accessory pulleys are aligned properly, I have a laser alignment tool for that... What ever you do .. DO NOT spray 'anything' on the belt or pulleys.. Will only enhance noise!! .. Make sure pulleys are clean.. 'Some' aftermarket tensioner are junk! .. Without looking at it myself, that's about all I can help you with.. Good luck! .. BTW, I have never let one leave the shop with a squeaky belt! .. So one of those suggestions should fix this for you...
