Belt Tensioner replacement

[lazyboy18]

Hey,

Does anyone know if you can just replace the pulley on the belt tensioner on a mazda 3 2012 2.5 engine? Or do I need to replace the whole unit?

Thanks,

Not sure. But when I did my 2010 in 2016 this is what I needed to buy for the mechanic. I think I ended up getting the tensioner too.
OEM Serpentine (Drive) belt + A/C belt replacement (tensioner and/or tensioner pulley may also be needed depending on condition and noise).
