You guys in Northern climates -- what do you do to prepare your
pressure washer for winter. Amazingly, my manual says absolutely
nothing about the subject.

I'd take it down in the basement if it was an electric model but its
gas powered so it must ramain out in the garage where the temperature
will plummet bellow freezing. Afraid the pump will freeze up and
crack. My idea was to fill the pump with 50/50 automotive antifreeze.
Is that the prevailing wisdom?

Run the gas out as normal. Then rig a funnel to a tube and
connect the tube to the water inlet. Fill the funnel with either
winter windshield washer solvent or RV antifreeze solvent. Crank the
engine/pump by hand without starting until you get the solvent to
run all the way through the pump. You're done until spring.

They also sell aerosol cans that do the same.
