Just did the timing belt, tensioner, serpentine, thermostat and water pump at 80k miles. Was advised by a friend to go ahead and replace the pump since I already had access to the part. Would hate having to remove the same stuff just to save a few dollars in parts.

Took me about five hours, but went through the maintenance manual I had thoroughly to make sure I wouldn't miss anything. Didn't even have to set at TDC, just made sure the camshafts did not rotate as I was replacing the water pump and belt. If you are mechanically inclined, I'd rate it a 6 out of 10 for difficulty.

BTW, a friend who worked for a Toyota dealership told me that there is enough clearance between the valves and pistons, that the belt could snap and you could still crank it and not damage the pistons, although I don't recommend trying to find out if it's true..
