235000 miles time to chang my timing belt again. Last time I did the whole 9 yards. This time I'm thinking just the belt and tensioner. Any comments? Where is the place to buy genuine Subaru the parts online now? The local Auto Zone has them but I don't know if they are as good. I think the last time I got them from Milford CT $60 for the belt and $99 for the tensioner. How is the Columbia, SC dealer for part prices?
