Just replaced mine in 45 min without pulling off any parts or loosening any fasteners. Use a 15mm 6 point on a 3/8 ratchet on the tensioner. Slide a breaker bar on the ratchet handle to reduce effort. Pull the belt off the top idler, remove the ratchet and then pull the belt off of the crank pulley. There is a tight fit between pulleys and pipes on the driver's side, but the belt can be squeezed past and removed. Put the new belt around crank first and rout it around driver's side pulleys using a long screwdriver (and skinny arms) to fiddle the belt into the tight space behind the pipes and under the large idler. Make sure the belt grooves are aligned and use the ratchet/breaker bar on the tensioner to slide the belt over the top pulley.
