Power steering fluid vs ATF+4
I need to add some fluid to the power steering on my van, but an not sure whether it should be standard power steering fluid or ATF+4. The fluid in there at present is red. I do know that the previous owner had warranty service work done that involved replacement of the two hoses and fluid to solve a "honk" problem from the power steering system, but I am on the road and don't have the paperwork to see what fluid they filled it with. I know that the normal fluid for this van is not ATF+4, but I would have thought standard power steering fluid would be amber, not red.
