Awesome! The s/c tensioner body was indeed held by a normally threaded 13mm nut! On my 2nd question, any advice for fitting the T47 TORX bit into the bolt holding the lowermost s/c idler pulley on? It's a very tight fit between the pulley and inner fenderwell. Rachet won't fit. Do I need to grind down the rachet and TORX a little bit?
