It is true that the water pump is a pain to remove. However, I did it without removing the fan pully or the harmonic balancer. The bolts were tough enough to get out with all the extra stuff in the way, Hind sight I wish I had removed at least the fan. But when you don't have the right tool, you jimmy rig it.
I did not need to lock the flywheel, as I didn't need to remove the harmonic balancer. To get the bolt off that was just under the edge of the harmonic balancer, we used a torch to make a small notch just big enough to get a wrench in there and loosen it off.
Then Entire job took 3 hours, plus a little extra for a few beers. ALl in all the job was worth doing myself because the dealer wanted about 700.00 for labour alone. I had to pay 280cnd for the pump itself. But, where else are you going to get it.
the pump iteself can be unbolted and might be able to repair the seal. I have not tried this yet, but I am sure it is possible.
Hope this helps!

Pay about $600.00 or get the book. You have to remove crank shaft pulley, timing chain cover, very hard job. You do not need to remove the crankshaft pulley to replace the water pump on a 3.4L v6. If one wanted to remove the water pump housing/timing chain cover on this engine, then yes removal of the crankshaft pulley would be needed. Maybe you are confusing this 3.4L with the 2.4L where as the water pump is driven by the timing chain. This kind of repair at the mechanic wouldn't cost more than $100. It is a very easy job and the water pumps for these engines range from $10 - $30. It took me only 30 minutes to replace my water pump, and I'm only a hobbyist. I only paid $13.99 for my water pump. I drive a 2001 Oldsmobile Alero 3.4L 3400 v6
Remove the side case and the water pump. Remove the right side case, and remove the impeller and shaft. Holding the back side of the impeller shaft with a wrench on the flat spots, you can now twist the impeller off.
The water pump runs on the timing belt. You have to take the timing cover off, remove the belt and then remove the water pump. If you reuse the timing belt, mark the belt with a spot of paint at the camshaft and crankshaft so that you can replace it and have the engine in time. If you need to replace the belt, make sure the engine is at top dead center on the timing mark before you remove the belt.
