Sounds like you have power steering , first thing to do is see if you have enough power steering fluid check and see by open the steering pump opener , refill to correct level if needed and check the belt what runs the pump for slackness , wear or slipping , ps go to a halfords store and thay will do all this for you if you can't do this your self good luck colin
I believe the power steering on your Astra van is an electrically operated hydraulic unit with a large fluid reservoir virtually on top of the steering gear?
If you have topped up the fluid enough for it to show on the little dipstick under the cap and the steering is stiffer towards one lock I would suspect a damaged steering gear but if the stiffness is uniform along the entire travel of the steering gear then the cause is probably low or non-existent hydraulic pressure.
The pumps do fail and need replacing sometimes and it isn't an easy job to do. I have not known one to stop suddenly because of pump or motor failure (but I have from electrical supply problems) and the only one I have needed to replace was very noisy. Usually the pump can't be heard above the noise of the engine.
With the aid of a wiring diagram and some small jumper leads the wiring can be disconnected from the pump and battery current supplied directly to the pump for the purpose of testing with out running the engine. If the pump can then be heard running and the steering is no longer stiff the problem is a fuse/wiring/electrical control type trouble and further investigation will be needed.
If the pump can't be heard running or the steering feels no better then the pump unit is probably faulty.
It would probably be wise to check the fuse first.
Good luck!
The flywheel is attached to the crank shaft and turned by the starter to get the engine running. It has nothing to do with the steering wheel. If your steering wheel is stiff it is because of the power steering pump or rack & pinion.
I don't know of any vehicles with PS bleed valves, would be surprised if Kia has any. The usual method to fill the lines and get air out, is to turn the steering wheel from stop to stop a few times. If wheels are hard to turn, you could raise both front tires off the ground. Keep checking the PS reservoir to top it up. And of course, car should be running. Don't hit the stops hard, just turn from stop to stop. Then let the car down and road test. If still stiff turning, repeat the procedure.
on some models the power steering pump runs both the brakes and the steering..look for a broken/missing belt and low/leaking fluid in the power steering pump..replace whats bad..
stopped in drive, engine shook is gross missing.
the belt snapped on front of engine, causing PS assist to end.
time for a new belt.
they last about 50,000 miles, best is to keep eye on belts.
or can be a long walk home.
or very expensive tow job.
the bent runs many important things, do not run the engine like this.
There are 2 things that cause power steering to go stiff. The power steering pump itself either from failure or "lack of fluid" and the rack and pinion assy under the car.
Most of the time the failure is the power steering pump itself. The teflon rollers fail inside the pump and it either stops providing an output pressure or it seizes up. You can loosen the power steering pump belt then try to rotate the pump by hand. It should move by hand. If it feels like it is intermittently locking up as you rotate, it the teflon rollers have failed and the pump will need to be replaced.
