This is the hose that goes from the rear center top of the block to the heater control valve, right? I just replaced mine with a piece of standard heater hose for $3.15 including clamps. I also replaced the little 90 degree bend hose on the rear passenger side top of block with a generic bypass hose from the local parts store for $4.99 . I went into the store with the old hose and they matched it up, simple and cheap.The only thing they couldn't find was that little rubber cap that is on the passenger side halfway down the block. The Toyota dealer said it didn't exist so if anyone knows where to get that or what the Toyota part# is, I would appreciate it.
