In this video, we're going to be working with our 2006 Chrysler 300. We're going to show you how to remove and replace your power steering fluid reservoir which is over here on the driver's front of engine bay. If you like this video, please click subscribe. We have a ton more information on this and many other vehicles and if you need this part for your car you can follow the link down in the description over to Here are the items you'll need for this repair.

Remove your power steering cap. Your power steering reservoir is located at the front of the engine bay on the driver side. Now, we're going to use a hand pump to siphon the fluid out. If you don't have one of these, you can pick one up cheap at pretty much any auto parts store or tool supply house or you can just use a turkey baster if you have one lying around that you don't need anymore. We'll place the suction side of our hose into the reservoir. We'll kind of wad up a paper towel around that and wedge it in there to help keep it from falling out. Make sure it's bottomed out all the way. We'll place the other side in our catch pan and just pump. Now, once you have suction going, you can just pull the top hose out of the pump and keep it lower than the reservoir and it will just continue to drain. You could just keep pumping it but this really is the fastest way to do it. If you have a piece of hose laying around, you could put the turkey baster in the end of the hose to create suction. Once you have suction, you can just pull the baster right off. Use this same method. Once the fluid has stopped draining, remove the other end of your hose. We have this paper towel handy to cap it off. Just place that in our drain bucket.

Push this tab off to the side and lift your power steering reservoir up. We'll actually put our cap back on now so we can rotate it and not worry about it leaking into the engine bay. I'm going to place some paper towels underneath because no matter how well you drain fluids there's usually still a little residue left. We'll take a pair of pliers, collapse the fittings on the end of the hose. Slide them both out of our way. Twist the hoses to release them from the end of your reservoir. Make sure they stay over the paper towel. If your hose is really stuck, twisting helps to break it free.

Now, a good trick for really stuck hoses is to use a straight pick and carefully pry it between the hose and whatever it's attached to, in this case our power steering pump. In this case our power steering reservoir. Once it's in there, be sure to always point it in, you don't want to face out and risk tearing the hose. Just kind of walk it around sideways and that'll help free it up. Then, you can twist it out and remove your reservoir. Now, unfortunately jobs like this are just messy. It's the nature of the system you're working on so make sure you have lots of paper towels handy, maybe some cleaners or solvent to clean up all that oil once its spilled.

Here we have our old power steering reservoir that we removed from our vehicle and our new part from As you can see these parts are exactly the same. They are the same size and shape. They have the same two fittings on the end. These are just some caps here to prevent debris from getting in there during shipping and storage. I’ll pop those off for you. It has the same fittings on the end and the ame bracket on the back. It even comes with a new cap which has your dip stick already in it.

Now, the reason that these are exactly the same is because this is a Mopar part, meaning that this is the OE part for Chryslers, Dodges, Jeeps and some other vehicles. If yours has cracked, broken, or become filled with debris or contaminated fluid, this new part from 1A Auto is going to go in direct fit just like your original equipment and fix you up right.

Reinstall the lines onto your power steering reservoir. Slide the claps back into place with your pliers. Move your reservoir off to the side and wipe up any fluid you spilled. Now, this stuff is not really corrosive and won't eat the paint but you don't want it dripping out onto the road or under your tires, so make sure you wipe it down as best as you can. You can use some oil removing solvents if you'd like. Line up the slides, push it in until it locks back in to your coolant reservoir.

Place some paper towels in and around your power steering reservoir as this next job can get a little messy. Remove your cap and you'll want a flashlight to see into the reservoir. Fill it about half way with ATF+4 or an equivalent automotive transmission fluid. Now, with the power steering reservoir cap off we're going to run our vehicle and move our steering wheel fully left and right a few times until the air bleeds out of the system. Check, fill and repeat as necessary.

Now, using your jack or a lift, lower the level so part of the weight is on the tires. You don't want the full weight on the vehicle just yet because it's going to make this job a lot harder. Start your vehicle and run the wheel from the full lock left and right positions a couple of times. That whining noise you're hearing, is the air in the power steering system. Your steering wheel may feel choppy and bouncy at first but once it gets easier, we'll add a little fluid and do it again.

Fill at about half of the capacity of the reservoir. If you go too high you'll have little fluid geysers coming out of the reservoir and again, that's why our paper towels are here but any mess we can avoid is less mess we need to clean up later. You can hear now that the noise has gotten smoother and a little bit quieter as well as the wheel getting easier to turn. Once you've got most of the noise to go away, lower the complete weight of the vehicle back onto the tires. Keep the processes going. You can hear it's getting quieter each time. Once it gets to about that level fill your reservoir, wipe up any excess power steering fluid, and test drive your vehicle. Now, any more noise you hear when driving the vehicle should go away after you've worked it through from driving around.
