How to change power steering fluid???

Hi guys,

I am going to change power steering fluid, i know i have to:
Get both My front wheels off ground.
Suck out fluid off power steering resorvoar, refill with new fresh fluid.
Disconnect Return hose.
Turn wheels with steering wheel from left to right and so on.
Make sure resorvoar is not going Low on fluid, add all the time.
Keep on like this until only fresh fluid comes out of Return hose.

I pull the return hose at the tank, install a cap on the tank and then put the return hose in a bottle. Start it up, flush, put more fluid in, flush, etc.

So mine are both 2002s so they have the *&#^*^%*@^%@ hydraulic fan and 2 returns. The return for you should still be the one on the back and bottom of the PS tank, right above the drive exhaust manifold. Unattach this and stick it in a bottle, but you must cap the tank or your new fluid will run right out. I dont lift the tire off the ground for flushing. Since it pushes the fluid straight out the wheels wont turn anyways. But if you do lift it off the ground and turn the wheels it could flush the gear a bit more, and will help with bleeding the system later. Your choice.

Be sure and only use the approved fluid, no generic fluids - I had a mechanic darn near ruin my hydraulic system by using regualr brake/PS fluid - the 4.7 has a 3-spd hydraulic fan that needs a lot of pressure - mixed fluids are bad, the fan won't run, and the engine will overheat.

I went out and got a quart of the stuff from the Stealership, think it was like $16-18 if I remember - cheap insurance.

It is a result of the relationship with Daimler, great German engineering but very specific tolerances and specifications - same thing for the Quadradrive axles and the need for a friction modifier. Dont cheap out on the fluids.

You are correct, it was introduced in '01 - I still say don't cheap out on fluids but if he doesn't have the hydro fan the fluid issue may be less important.

I used a turkey baster to suck it out. Since I have the hyd setup and it's always circulating I just did it a few times then did it a few more times a few days later
