Bleed power steering system

How do you Bleed a power steering pump?

After replacing a power steering pump or pressure hose, it’s always a good plan to flush and bleed the power steering system of air. For most power steering-equipped vehicles, this is a simple process. Turning the steering wheel lock to lock several times will remove any unwanted air in there.

Close the cap to keep fluid from popping out while you bleed the system. Bleeding the power steering lines forces air out of the system. This can cause power steering fluid to spill out of the reservoir as the pressure in the power steering lines increases.

Does bleeding power steering fluid remove bubbles?

Bleeding the power steering fluid won’t remove any bubbles if there’s a leak inside the system. If you see bubbles, you’ll want to check for leaks inside the system and fix those before bleeding the power steering fluid. Check your owner’s manual and use the fluid your vehicle manufacturer recommends that works for your vehicle.

Can You Bleed power steering with a cap on?

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.

Do you need a bleed valve for power steering?

Most vehicles don’t come with one because it’s fairly easy to bleed the power steering without a vacuum kit. You can buy a reservoir cap with a bleed valve adaptor on the lid if you want to use a vacuum kit to pump your power steering lines but you don’t have a built-in bleed valve.

How do you check a power steering bleed valve?

Read your vehicle’s manual to see if your power steering has a bleed valve. If it does, purchase a vacuum pump kit for a power steering system and slide the end of the vacuum pump’s hose over the bleed valve. Then, pull the trigger on the vacuum until the gauge on the pump reads 20 Hg (inches of mercury).
