New here with questions

[bugs7232]

Hey guys new here so dont really know what to expect.
I have a 2003 GMC Yukon. Bought it new. Recently I changed the main belt tensioner and belt. I now have a problem with the belt wanting to ride off the lower pully between tensioner and crank pulley. Never noticed this before, so I put old tensioner back on, and I have the same problem. Could be it was trying to ride off before repairs, but I never had a belt issue before. Changed tensioner because it seemed to be getting weak allowing belt to squeel a bit. Have no clue now. Any ideas? Thanks

What brand of belt did you buy? I ask cause I haven't had any good luck with belts without goodyear gatorback being on them. Other than that, I have no idea's.
