Oil Pump Removal Fail – Alternator Bracket Removal GM Chevy Tahoe Vortec LS Engine vid 11

Oil pump for the GM 5.3 Vortec LS Engine is much harder to remove than it should be.

Oil pump for the GM 5.3 Vortec LS Engine is much harder to remove than it should be.

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.

Remove Alternator, Valve Covers, Rocker Arms, Push Rods GM Chevy Tahoe Vortec Engine LS vid 8

I’m happy to say that the removal of the alternator, valve covers, rocker arms, and push rods was very easy!  Everything went exactly as you would expect them to go.  My only exception was the dramatic difference in coloring of the rocker arms and valve springs from the passenger side to the driver’s side.  Passenger side was gold in color and (to me) looked healthy.

The driver’s side looked brown, burnt, and very unhealthy.  I posted a question on one of the Tahoe discussion boards, and never heard back from anyone.  So either, it was a stupid question, or no one knew the answer.  I still don’t know.

You will notice the careless way I threw all the push rods in the box.  I already purchased a cam, new springs (and hardware), new rocker arms, and new push rods, so I was not too concerned about where everything ended up.  I did keep the rockers in order, just in case something came up that I needed to identify what was what.  If you are planning a cam swap without replacing the push rods and rockers, take care in knowing exactly where everything came from.

By the way, you can’t pull the valve covers until you have removed the spark plug coil packs (check out Video 5).
