Remove Water Pump, Harmonic Balancer Pulley Bolt – GM Chevy Tahoe Vortec Engine LS Video 3

With the radiator, fan shroud, and fan out of the way, (see video 2) the water pump removal is actually quite easy.

I removed the tensioner pulley, then the thermostat housing and 6 bolts later, the water pump was off.  Special thanks to a guy who goes by OldskoolFunk on YouTube for cautioning us that the water pump bolts are a little different, and use of a template is very helpful.

I wish I could say the harmonic balancer pulley bolt was just as easy, but it is not.  It’s on there, and on there good!  The hardest part is the fact that torqueing the bolt moves the pulley, too.  I tried a strap wrench, but there was no way.  I hit it with penetrating blaster and let it soak overnight.  The next day, it was a combination of heat and an air wrench that got it off.  Here’s the video.
