I know Power Steering Fluid will eat the seals in some PS systems - they use ATF (like my Toyota). No amount of searching reveals anything on GM systems other than various opinions on what type of over priced synthetic has more magical qualities than the other. I just need to know what's the correct/compatible fluid for a 2001 Sierra 1500 4x4.
The cap says "Use Approved Fluid" but I'm not buying it from the dealer. Can I just put ATF in (other than Dexron IV, which apparently isn't good for PS)? Will P/S fluid kill the P/S system?
