[00:00:00] When you turn the steering wheel and it’s stiff, hard to turn or worse, you hear this humming sound, (engine) You may need to fill or flush your power steering fluid. This is what you will need to get the job done. Turkey syringe, catch can, safety goggles, gloves, power steering fluid, pliers, rags, and a funnel. I’m Larry Kosilla, a professional detailer and trainer for the last 15 years, but when it comes to what’s under the hood, I’m the student. Follow me as the experts teach me to diagnose, fix

[00:00:30] and mod cars at autoblog’s Wrenched. – Okay, Spence, I have to be honest, I’ve never thought about changing the power steering fluid. When would be a good time to throw that away? – Well, they don’t really have many recommendations if you look in their manual. There are three different ways to do this. The first would be to look at the liquid and top it up if necessary. The second would be to suck all the fluid out of the reservoir and put new fluid in it and the third would be to completely flush the system. – [Larry] Check your manual

[00:01:00] for the type of power steering fluid recommended by the manufacturer and then locate the reservoir. It will have a logo on the steering wheel or the words power steering fluid and “Do Not Overfill” around the cap. Twist off the cap and simply check the dipstick which will have dashed lines indicating high and low levels and add more if it is low. Pretty simple. Option two is to use a turkey baster or vacuum pump to remove some of the old liquid and replace it with new liquid. This is a quick and easy way to get a cleaner percentage.

[00:01:30] from dirty to clean liquid and takes less than five minutes to do. Option three, as Spencer mentioned, is to flush the system. This will remove most, if not all, of the old fluid and replace it with clean power steering fluid. First, make sure the front wheels of your car are off the ground, as you will need to turn the steering wheel freely for this method. Next, remove most of the liquid with a turkey baster as we did in option two, but leave some liquid remaining to prevent the pump from drying out. Then slide your catch can under the power steering reservoir

[00:02:00] and find the low pressure line. Some systems will have a permanent clamp on the high pressure line, so look for the one with the removable clamp as this will be the low pressure line. Use pliers to release the hose, then point the hose down into the catch can. (serene music) Next, add fresh fluid to the reservoir and fill it up before starting the car to flush. Now, with an extra pair of hands, start the car so the pump removes the old fluid.

[00:02:30] through the hose and into the catch can until the color changes to clear or clean. Don’t let the car run for more than five to eight seconds, as you don’t want the power steering pump to dry out. You’ll know very quickly when new fluid from the reservoir starts to shoot out of the hose, then it’s time to shut off the engine. Take the used fluid to your local auto parts store or hazardous waste collection center for recycling. Now that the fluid looks clean, replace the low pressure hose and clamp, then refill the power steering reservoir.

[00:03:00] to the full line one more time. Before tightening the cap, turn the wheel back and forth to bleed air from the system. Then start the car for 10 to 15 seconds to allow the power steering pump to suck up more fluid because sometimes you will notice a drop in fluid level as you fill the air bags so you will have to refill the Deposit. as necessary. With the fluid looking full, take a quick ride to bring the power steering temperature up, then go back and check the levels one more time and top up if necessary.

[00:03:30] Finally, double check your work for leaks and clean the hoses of any previous spills. This will help you notice any future leaks in the future. Keeping up with your power steering fluid is incredibly easy. Just remember, check its level and color every time you change your engine oil. By doing so you could avoid the annoying squeak or permanently burn out your pump. To view more auto repair instructional videos, visit I’m Larry Kosilla from As always, thanks for watching.
