Saved $$$ DYI
2011 WRX Hatch here. Subaru dealership quoted me at $115 to replace this belt as mine was severly cracked. To save money I thought I'd give it a try and do it myself. I had the tensioner fully released and alternator fully dropped and still had a hell of time getting this belt on ( maybe because it's new and stiffer ) Finally got it installed in about an hour and saved myself some money in the end. Thanks IRR!
