Removing Power Steering Pump
« on: July 21, 2022, 10:41:19 AM »
I have a 1986 GMC Jimmy full size, 350. I need to replace the power steering pump because of leakage. I am wondering if I need to move the AC compressor and the fan shroud in order to do so. Is it easier to remove the pulley before removal of the pump/reservoir ?   Many thanks for any help.

Mine is an 87, but I believe you can sneak it out with removing the other stuff....

You can remove it alone without the other components.

Easier to remove complete, then bench work on the pulley etc.

Loosen the pressure line while in place if possible. Remember, a quick snap, not a long tug.

More than 3 times and you're playing with it!  ;D

On the other hand, you know what they say.  Practice makes perfect!    :P



With some pump configurations, it helps to own a comprehensive set of short extensions and combination wrenches.  Use a proper 6-point flare nut wrench and open-end on the pressure hose fitting and large flow control valve nut.  Once the pump is on the bench, use the appropriate pulley remover/installer tool so as not to damage the pump internally.  When adjusting the pump belt, use a specialized tool designed for the purpose (image).  The pump reservoirs are easily dented and distorted so avoid prying against the pump reservoir if it's married to the pump body.

@BD. Can you describe to me how that tool works? I'm currently having a heck of a time getting the proper tension on my PS belt. Seems the prior owner reefed on the upper outer welded nut, so I can't lever that to lift the pump into place.

I can absolutely try to locate that tool, but I just want to be sure I know where to put it on the bracket so I don't damage anything.

The tool hooks the bottom outer edge of the pump bracket and levers upward and inward against the flat outer face of the bracket, providing excellent leverage to tension the shorter pump belt without imparting any force against the pump body or reservoir.  The tool is broached for a 1/2" drive long-handle ratchet and works remarkably well - a brilliant design.  The longer belt is tensioned last by pivoting the A/C compressor.  I'll snap a pic of it in use this weekend if I get the opportunity.
