How do I remove the fan/clutch assembly from the water pump? It is screwed onto the shaft of the water pump. How do I keep the shaft from turning while trying to unscrew it? This is on a 2003 Silverado 1500 with the 5.3L engine.

 

Harbor Freight carries a kit for it. I always jammed it so it can't spin. Pain in the a** Lord knows

 

Typically use a specialty tool you can rent from parts stores.

 

fan clutch wrench and a hammer works.


I use an air hammer with a long chisel bit. a couple hits straight down to create a notch and them a angle hit into the notch to spin the fan off....off in seconds.

 

This works well too. lol

 

My new favorite way!

 

you can get wrench sets, the one I have has an adapter for use with an air hammer and I just leave the belt on until its loose

 

Problem solved. I saw different special tools online and just made one up
