When I worked at a shop in my early 20's (10 years ago). We charged $90 an hour for labor and we where not even certified. To get a timing belt change would take me about 4 hours not including a 15 minute break every hour on the hour, so like 5 hours, plus maybe a little bit extra time for making sure that everything is perfect. I don't think that shops give breaks like that anymore

 

I just finished an '01 V-6 timing belt. I was fearing the worst after reading about everyones bad experiences with harmonic balance bolts. I got one of the $30 holding tools from the abundance available on e-bay, squared up the wrenches and got mine off with one good hard crank. As for timing the cams, I checked with the dealer who told me to line up the number '1' mark on the front camp pulley with the hash mark behind it on the block, then line up the solo hash mark on the rear pulley with its 12 o'clock block mark. The crank pulley then is obviously keyed, so you just turn the cams once the belt is set til it lines up. Just in case, I marked my old belt to all the pulleys before I started and in the end they lined up perfectly using the dealers advice. It's always a good test to turn the whole rotating assembly over several times by hand before you start the engine to check for clearance.

Best regards
