Thread: How to Flush/Change Power Steering Fluid on the 3800/3.8L Engine

Awesome write up! I'll be doing a flush this weekend and following this guide for sure. Thanks!

Great instructions on this overlooked procedure. I am sure not many car owners give a thought to changing power steering fluid.
I followed your procedure in a 2002 GP with 185K. Fluid was changed one other time, about 100K.
I have been experiencing a noisy steering pump at times. Flushing and putting in new fluid made pump much more quiet.
Before the fluid change, I once saw some power steering fluid on floor, about a tablespoon amount. This was on the drivers side. Can't tell where the steering fluid was leaking from.
I believe my rack may be slowing going, but I have not experienced any symptoms of bad steering, just the fluid lead which happened 5000 miles ago. I checked the level and had to add a small amount.
The GP is a daily driver, so I have been watching for more problems to develop, but so far, so good.
