Greetings,
The accessory drive belt tensioner needs replacing as it is making noise. I got a replacement from IDP and was going to put it in until I noticed that the pulley looks different. The one on my '04 XC70 has ribs that correspond to the ribs on the belt (I installed a new belt). The replacement's pulley is completely smooth. I checked online to see if a ribbed tensioner pulley was available and all I can find are smooth ones. Was there a change and would a smooth tensioner be appropriate?
Thanks
