Removing the oil pump – oh what a joy!  The 4 bolts on the front are obvious, but the pump is also connected to the oil pickup that is in the oil pan.  Guess where the bolt is?   Yep, inside the pan, and not only inside, but GM had 2 possible locations for the bolt and they chose the harder of the two to attach it.  Dropping the pan is another 6000 step process that I did not want to mess with.  Looking back, I think that at this point in the game, I knew I was gonna pull the engine, and I knew that getting the oil pump off post removal would be easier, so I punted, and moved on to the alternator/power steering pump bracket.

The goal here was to not open up the power steering system to avoid having to deal with it later.  I just started removing bolts till I found the ones that held the big bracket on to the engine block.  Finally I was able to pull it away and secure it to the side.  This [pulling aside and not opening up the system] was my plan for the upcoming AC compressor, too.

I didn’t make a whole lot of progress during this section, so I cleaned up the garage.  I wanted to make sure that I knew where everything was, that everything was with their corresponding fastener bags, and that sensitive items where in the back of the Tahoe where they couldn’t be kicked, or lost by passersby in the garage.
