#1 and #2. In the engine bay, comes over the rear of the engine. If you take the rear fuel tank cover down, have a close look at 12 and 23.

The vario cam works by modifying the path the chain takes from the ex to the int cam. The ex cam is fixed timing and the intake can vary depending on RPM. A solenoid directs oil pressure into the vario cam hub in between the two cams to make the top or bottom distance longer which changes the intake timing.

Yes, it worked just fine. There are some who subscribe to the "just do it by feel" method, but unless you do it to a known tension a few times, there's no way to develop that "feel".

I think I will go for the tool kit with the tension tool, belt lock (I think 944 only) and combo wrench then look for a flywheel lock and should be set on special tools for this job...

I just asked this question of Mike and Jonathan of Pelican and ECS respectively:

Do I really need or even want to do the water pump? I have zero desire to cheap out, so if its a smart time to do it because I will have all the belts already off, I am on board. But I have also seen some complaints of failures with replacement water pumps. Am I just introducing a new potential failure or leak by fixing something that isn't broken and only has 58k miles?
