Follow these steps carefully
Park on level ground, set the parking brake, and shut the engine off. Have a turkey baster or fluid syringe, a drain pan, and rags ready.
I've learned to pour the old fluid back into the new fluid's jug and drop it at the parts store. Most take it free — no excuse for the storm drain.
On the 2001-2006 Acura MDX: the power-steering reservoir sits in the engine bay on the passenger side, a small translucent plastic tank with a black cap, mounted near the strut tower. Wipe the cap and the surrounding area completely clean before opening it so dirt cannot fall into the system — one grain of grit in the pump or rack shortens its life. Pop the cap and note the HOT and COLD level marks on the side of the tank. Check the fluid condition: healthy Honda fluid is light amber; dark brown or black fluid with a burnt smell means the system is overdue and a simple top-off will not fix it.
On the 2001-2006 Acura MDX: remove the cap and read the level against the HOT/COLD marks for the current engine temperature. Inspect the fluid closely — glitter or metal particles mean pump or rack wear, and foamy fluid suggests air is being drawn in through a leaking suction hose or O-ring, which a flush alone will not cure. Also check the rubber return hose and the metal pressure line for wetness; the return hose clamps on these trucks are a common seep point. If the system is empty from a leak, find and repair the leak first — running the pump dry destroys it in minutes.
Slide cardboard under it overnight after the repair. A dry floor in the morning is the only test I fully trust.
On the 2001-2006 Acura MDX: use only Honda/Acura-spec power steering fluid — this system is not tolerant of generic fluids, and the wrong fluid causes noisy operation and seal swelling. The DIY flush method: suck the old fluid out of the reservoir with a turkey baster, refill with fresh fluid, start the engine, turn the wheel lock-to-lock a few times, shut off, and repeat the suck-and-fill cycle until the fluid coming out looks as clean as what went in. Work the steering gently with the wheels on the ground and never hold the wheel hard against the lock, which spikes system pressure. Top the reservoir to the correct HOT or COLD mark — do not overfill, or it will puke out the vent.
With the engine running and the 2001-2006 Acura MDX safely stationary, turn the steering wheel slowly lock-to-lock three or four times to purge trapped air, pausing a few seconds at each side. Shut the engine off, recheck the reservoir level, and top off as needed — the level will drop slightly as air works out. Inspect the pump, hoses, and rack boots for fresh leaks while the system is pressurized. Take a short drive and listen: the steering should be quiet and consistent. Any remaining whine, stiffness when cold, or foaming in the reservoir means air is still entering or the pump is worn.
Trapped air causes most 'I just fixed it and now it doesn't work right' comebacks. Take the extra ten minutes and bleed it properly.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
