If you want to flush the fluid just disconnect the return hose from the power steering cooler (right next to the reservoir) and stick it into a plastic bottle. Suck all the old fluid out of the reservoir first with a syringe, baster or pump. Then fill the reservoir with new fluid.
Get a helper to start the engine whilst you steadily pour fresh fluid into the reservoir, since the level will immediately start dropping as the p/s pump sucks the new fluid through and dumps the old stuff into the plastic bottle. You will need anywhere from 500ml to 1L to get all the old stuff out. Once clean fluid is coming out into the bottle stop the engine, hook the hose back up and top up the reservoir if needed.
Then do the full lock to full lock a few times, go for a drive and top up fluid again if needed. (Or suck some out if you have overfilled). The fluid according to the manual never needs to be changed but it's good idea to do it every couple of years because the fluid does go off. $15 of fluid every 2 years is better than thousands for a new rack.
I just use the standard Castrol power steering fluid it's fine.
Thank you!!! AWESOME INFO this forum is helping me heaps.
Okay - just so i got this straight before i break something (using all my car knowledge to try to explain)
Its hard to see what hoses are where cos i have this big plastic black thing (tech term) above my steering reservoir.
Is the "return hose from the power steering cooler (right next to the reservoir)" connected to the reservoir?
I can see one hose from the bottom of the reservoir, i am guessing this is the hose to the p/s pump?... are the wheels the black rubber things that touch the road?
Sorry to ask such stupid questions, just dont wanna pump fluid into any old ho..se
