Can you over tighten a fan belt?
Help! Dear Anthony: A belt should never be over-tightened. An over-tightened belt can burn out any bearing that the belt rotates on, including alternator, power steering pump, A/C compressor, idler pulleys, etc. An over-tightened timing belt can ruin any pulley bearing it is connected with.
