The oil in my power steering is black how do I change it

First thing you need to do is remove thwe return line from your power steering reservoir. Thats the thing you put the power steering fluid in. Run that hose to a large container where you can catch a lot of fluid in. Now you want to make sure you have your new power steering fluid on hand before you start and another person would be very helpful also. Have your helper start the car and turn the wheel back and forth while you pour power steering fluid in the reservoir. Do not let your power steering fluid run completely out you can ruin your pump and or steering box. Continue to pour in new steering fluid until the fluid coming out of the hose thats in the bucket is clean fluid. Turn vehicle off reconect the hose to the reservoir and top off. With the lid off reservoir start the vehicle back up and turn wheel all the way back and forth many times(do not turn it to its furthest position where it bumps) continue to make sure the fluid level is always full. By turning the wheel back and forth you are bleeding the lines to get all the air out. Do that a few times, refill and put the cap back on. You just changed your power steering fluid. I f your vehicle is old you may want to get new rubber hoses for your power steering system. hoses degrade over time and eventually they start to flake off into your fluid which can damage parts. Always a good idea to replace hoses especially if they are soft.

Power steering fluid is black, foamy, and smells burnt...
