Tensioner pulley for RB26DETT

RB26DETT Tensioner pulley. Trust me, after years of doing this. If you are going to replace the timing belt on your RB, replace the water pump, the idler, and the tensioner pulley. If you don't there is about a 50/50 chance that you will hear the "whoo, whoo, whoo" noise coming from one of the bearings.  While you have the front of the engine off, the water pump is another good part to replace.
