Regardless of what type of vehicle you have, it is extremely difficult to replace a serpentine belt w/o a serpentine un-tension-er tool. This is a thin, long handle with a socket on the end that sticks out at 90 degrees of the handle. The socket slips onto the bolt-head of the tension-er pulley. Once the serpentine belt is threaded around all the other pulleys you put the un-tension-er tool on the tension-er pulley bolt and pull (or push) to achieve slack in the serpentine belt and slip it on the tension-er pulley.
