Started having issues with the PS on my 2008 Caddie CTS. Intermittent power loss, and whining noise started shortly after.
Background - I had changed the PS fluid about 2 years ago...probably 20k miles ago with fresh OEM (AC DELCO) fluid. Looking at the fluid on the stick and in the black reservoir it looks ok but pulling out a sample and putting it into a clear glass it is definitely brown - Why did it turn so fast?? I also have a 2005 Chevy Colorado that I changed out at the same time with the exact same fluid. My son drives the truck so it probably has about 10k miles since the change. I decided to pull a sample out of its PS reservoir and ITS WORSE...It is a deep dark brown!! Is there a chance I got some bad fluid? Is it frying my pump?
Attached pic from left to right....OEM fluid bottle left over after my change - Glass 1 is fresh fluid from that bottle - glass 2 Fluid from my Caddie - Glass 3 Fluid from the Colorado. Is this normal? Would you recommend changing it out? If so, with what fluid? I don't want to put the AC Delco back in if it can't make it even 20k miles!
