Power steering pump chirps twice, why?

[KeithG]

I predict this is a easy question, but who knows.

My 97 Camry makes a couple of quick chirps when the power steering system is at max output and cold. I.e. when I back up and turn out of our gravel parking pad in the morning.

I replaced all the belts last fall. Is the chirping most likely because the best it too tight or too loose?

I did replace the PS fluid with ATF this spring. I don't think I introduced any air into the system.

Thanks!

The chirping is probably external, from the drive belt or pulleys.
Anti freeze or oil on a belt can do this until it warms up. Dry or worn belts can do this. Usually loose, but maybe too tight will also cause a noise.
Next to check are pulleys. You can yank the belt and turn them individually to perform a quick test.
But you mentioned "max output". This means a hard turn, maybe against the stops [I never do this - pressure spikes and goes WAY up].
90% it's your drive belt system.
