no, simple job from the top. without the intake it is literally a 10 minute job and plenty of room. Just need a 10mm socket on the tensioner. When putting the belts back on, don't be afraid to apply the pressure to the tensioner. There's a little extra give you need to slip the belt onto a smooth pulley.
you could also use this as a good excuse to do your intake. take out the stock, change both belts (best prices are on ebay), install new intake. smile.
