Jim, you might consider removing the charge air cooler as it is pretty easy and really opens up the area you need access to. I don't believe the floor panel removal will help as it is located over the rear of the engine. I have had the charge air cooler out several times and find it gets easier each time. I check my belt each time and with 80,000 miles I don't have any cracks on the belt so will continue using it. Have a great day.
