I just had my timing belt, fan belt, ps belt, ac belt, tensioner, crankshaft seal and rear brakes done at the dealer ($669.00 does that sound about right?). Now when i drive at high speeds 60-80mph if I let off the gas just a little it makes this dragging noise? but if i take my foot off the gas all the way it doesnt. I took it back to the dealer and they said it was my engine fan. My engine fan has a broken wing but it never made this noise before. They said I need a new fan. Does this sound right?
