Park safely: To begin bleeding power steering, you will have to park in a safe place on a plain surface that helps your car balance. Then, take a moment to allow the engine to cool down.

Check the fluid level: Next, open the hood of the car and locate the steering fluid reservoir. It is usually found near the coolant reservoir on the left side of the engine bay (on the passenger side) or on top of the power steering pump.

However, the location may differ from one vehicle to another. So, to be sure, you may have to check your car’s manufacturer’s manual.

Once you locate the reservoir, kindly check the fluid level to know whether you need to add some more fluid to top it off before you bleed the steering.

Add steering fluid: Ensure to top the fluid with the type of fluid strictly recommended by your vehicle manufacturer to avoid any complications.

Jerk up the vehicle: After topping off the fluid, get a strong floor jack and lift the wheels of the vehicle off the ground. Ensure to use a standard jack.

Start the vehicle: Next, go ahead and start the vehicle.

Turn the steering back and forth: Once you start the engine, slowly turn the car’s steering wheel back and forth (from left to right and vice versa).

Do this 8 to 10 times non-stop without hitting the locks or stops to prevent damaging the seal. By doing this, air will be forced into the steering fluid reservoir and out of the system.

Some people ask whether it is okay to bleed power steering with a cap on or off. It is important to note that you must keep the reservoir cap on to avoid bubbling fluid pouring out while bleeding the power steering. However, keep it slightly loose for a constant refill.

Monitor the fluid level: You may not be able to turn the steering wheel and check the fluid level simultaneously, so it would be helpful to have someone else monitor the fluid level so that it doesn’t go down and empty completely.

Add fluid (if necessary): If the fluid seems to go down, you may need to add some more fluid so that the reservoir doesn’t empty.

Go on with steps 6 and 7 some more: Turn the steering and check the fluid level some more until you can no longer see any more bubbles.

Turn off the engine: Once you are satisfied that the air bubbles are out completely, turn off the car’s engine. There you go; you’ve just completed the process. If the air doesn’t go out totally, you may have to consult your mechanic to find out why the power steering pump will not bleed air out of the system completely.

This process above is a generic approach. Some manufacturers recommend a specific method for their vehicle makes and models. The bleeding can be done once you identify the power steering bleeding valve location.
