fan belt problems

[94f450sd]

whats the correct belt for my 95?since my engine swap ive been replaceing the belt every 2 weeks or less.a couple times the belt was too long to fit so i had to get another one.after about a week they stretch and start squeeling.itll get so bad that i cant use my A/C without it squeeling.i replaced it the other night again and the new belt was once again way too long.i am now rideing around with 6 washers under the A/C compresser mounts.and its starting to squeel after 2 days again.nothing has changed in my accessory brackets or pullys.my tensioner is new.

if somebody has a part number that would be great.

Check the alignment on ALL your pulleys, especially the vac pump and tensioner.

Please don't ask how I know you need to put a good eyeball on those pulleys every now and then

serpentine belts do NOT stretch...

replace the tensioner, and check the pulley alignment
