Power Steering Flushing
« on: 30 August 2019, 15:59:50 »

Hi Guys

Has anyone out there got any bright ideas, first off Iím talking about the Omega with the 2.5 L diesel engine not that I think in this instance it will make any difference if it was petrol.

My problem is the power steering has packed up and the fault was traced to the pump which has now been taken off and sent for repair.
The repairers have said the system needs to be flushed out before fitting the repaired pump which all makes good sense to me.

Ok there are two pipes which connect onto the fluid top up reservoir, one goes down and connects to the power steering pump via a banjo union unlike the one shown at B in the image but the same as the one shown at A.

Does anyone know the best way to flush the system out from the banjo at A, or could I simply pour fluid in at point C until it comes out at banjo A, although I think point C is the return fluid pipe so I would be flushing the system in reverse if you get my meaning.

Thanks to anyone who can shed some light

I guess just disconnect the return hose to the reservoir, remove and flush the reservoir then block the channel where the return hose was, fill with fresh fluid, run the engine until the fluid has gone, catching what comes out of the return hose, and repeat until you get clean fluid with no debris from the return hose. :y

ATF is cheap, and the hoses from and to the reservoir are attached with hose clamps.


So, attach a larger reservoir to the supply hose and extend the return hose into a bucket.


Fill the reservoir, start the engine, and keep turning the steering wheel lock to lock until clean fluid comes out. That probably won't take long as it's not like engine oil.

Yeah, I should have said catching and discarding what comes out of the return hose. :-[

Just suck the oil out from the resovior, then refill, drive around, repeat step 1 job done.
