I was at the dealer a few years ago and happened to ask what they would charge. He said 1 hour labor - $50 or so at the time. I handed him the keys.
It must have been a long few years ago I assume . Last year when mine went, the stealership told me that they would have to remove the hood and raise the engine to replae that, for $900.00. I got the silicon PHH for $30.00 and did it myself. Love that 8mm ratchet wrench. I just love it .
