2003 Liberty power steering fluid
I have a 2003 Liberty LTD and I need to top off the power steering fluid reservoir. My owners manual says that it takes power steering fluid meeting spec MS-5931. However, I'm reading online that Chrysler used ATF +4 fluid in their power steering systems for these vehicles. The Haynes repair manual (for 2002-04) also recommends ATF +4. Does anyone know why the difference? Is it a big deal if I use the wrong one?
