Car leaking orange liquid?

Sounds like power steering fluid to me since Power steering fluid is normally an Amber color although i could be antifreeze. GM used orange antifreeze in their vehicals for a long time. If the leak is towards the front of the vehical check the radiator and all hoses from it If its further back under the car check the transmission although transmission fluid is normally an unmistakable red color. If it is somewhere in between the 2 then look at the power steering pump and lines. Its all about process of elimination.
