4. Link the other end of the tube to a drain pan or container, which will collect the old fluid.

5. Start the engine and crack open the bleeding valves a little

2. You will hear noise anytime you turn the steering. It is due to the air in the system obstructing the movement of the power steering fluid. When this happens, the parts will not receive proper lubrication.

3. Driving with so much air in the steering system could damage the steering pump. The air in the system is compressed by the fluid, causing a certain amount of pressure that could force through the seals and cause the valve in the pump to jam open.

4. The air in the fluid could also cause fluid cavitation, which could damage the pump.

Can You Bleed Power Steering With The Car On?

Yes, you can bleed the power steering with the car on, allowing more effortless steering movement during the bleeding process. However, turning on the vehicle while bleeding the power steering is not compulsory. You could switch the key to ignition, which will also get you to turn the steering during the process better.

The steering can be very stiff and impossible to move when the engine is switched off, or it is not switched to ignition. It will make it impossible for you to bleed the steering properly because you cannot move the steering to create enough pressure to push the air out from the drain of the plug.


When your steering becomes stiff and makes noises, there could be air in the system, or the fluid is down. A more severe cause could be damage to the rack and pinion steering system. You can check the power steering fluid if it is down. If it is not the cause, you should proceed to have the system bled. Doing this will get all the air out of the system, and your steering can move more freely without disturbing noise.
