Squealing power steering belt

When started during cold weather power steering belt slips and squeals for 60 seconds. Then is okay. Also intermittently slips and squeals while turning afterward. The colder it gets the more it happens. Doesn't squeal in warm weather at all.

Three different manufacturer's belts were changed. All quiet in summer and noise happens as it gets colder on all three.

It's absolutely the power steering belt area. Properly tightened. Squirting water on belt silences it temporarily. Checked alignment, pulleys, and power steering pump. Last belt was a OEM Hyundai part bought at dealer. Pump spins freely. Fluid changed. I've since been told this is a problem with some of the pulleys and the belt and the only way to fix it was to get an actual Hyundai OEM belt. Tried that. No joy.
