Larry:

With the proper tools (I borrowed them from my friend), it took me exactly 6 hrs from parking the car to starting it to test the seal. Would have been faster if I'd known that the belt tensioner shock pushes the belt pulley so far over.

I'm sure it would be somewhat faster the second and third time, but I'd expect someone who has not done this before to take just about 6 hours.

The water pump bolts are a little fiddly, but can be reached with swivel sockets or extensions without too much trouble.
