Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

Remove this plastic cover. It has three 10 millimeter bolts. Two on this side and one on this side. Use a flat bladed screwdriver to loosen the hose clamp, or use an eight millimeter socket and ratchet. I find that's a little easier and it doesn't slip off. I'm going to pull this hose out of here. Turn that to the side. Unclip this connector here, and place that aside.

Pull the intake tube off of the throttle body. There's another vacuum hose down here, so pull that off. Lift the intake off. It's on rubber mounts. One more connector. Push the lock tab in and pull it apart. Place the intake aside.

Down here is the auto tensioner. That's what gives tension to the belt. There is a square opening here that is for a half inch driver or a breaker bar. What I'm going to do is take this end of the breaker bar, put it into that opening, and then I'll pull it to the driver's side to relieve tension from the belt, and I can pull it off the pulleys. It's a little tricky to get in here.

Got it in there. I'm just going to push it down to the driver's side. Belt is loose, so I can just lift it off. I can relieve the tension. Pull the breaker bar out. Feed the belt off around the pulleys. Remove the serpentine belt.

Before I remove any of the power steering lines, I'm going to drain off the fluid in the reservoir so there's less fluid to drain out of the lines when I disconnect them from the pump. I'm just using a fluid transfer, like a suction gun and just dispose of it properly. Once you've drained it, replace the cap so nothing falls in there. Raise and support your vehicle. If it's easier, you can take your wheel off. We've just turned the wheel.

You need to remove this high pressure line from the steering box. Our vehicle here has like a three inch body lift, so there's quite a bit of space here. On a stock vehicle, you may be working through this opening, and you can pull the clips and pull this rubber out of the way to get to it. I'm going to spray some rust penetrant on it.

I'm going to take a 14 millimeter line wrench to remove the pressure line from the top of the steering box. The line wrench is more closed than a regular open wrench. Gives you a better grip on a line faster. That actually loosened up pretty well. Just have to work around the fan here. It contacts with the fan a little bit, but it you spin the wrench between the fan blades—you've got enough space. Before you pull this off completely, have a drain pan ready to catch any leaking power steering fluid.

Now that I've let the majority of the extra fluid drip out of here, I'm just going to take an extra latex glove I have. Put it over it and zip-tie. This way it'll keep some of the fluid contained while I get the power steering pump out. I'm going to start by removing the two lower bolts from the power steering pump. There's one in here, and then one here. I'm just going to use some break parts cleaner to clean some of the grime off so I can see the bolt heads better. I'm going to start with the back one. It's 10 millimeter. I put quite a bit of force on that to undo it and with the little short 10 millimeter wrench. It's kind of difficult, but there's not much else you can get in there. Now that they're broken loose, I'm going to use a 10 millimeter ratcheting wrench.

I'm trying to speed this up a bit. Those are actually pretty loose, so I can move them out by hand. I'm going to leave them in there for now. Need to go up to the top part of the pump and get the top two bolts. I also need to undo the low pressure return line. It's got a squeeze clamp here. I'm going to do that now.

I'm going to undo this clamp here on the low pressure hose. I'm just going to use some slip joint pliers. That's better. Reach in and push this up. Just slide it up the hose. That should be off of the neck of the power steering pump. I'm going to lift it up.

You're going to want to have a drain pan ready because some fluid will pour out of here. Not too much actually because we drained a lot out earlier so that's good. I'm just going to push the hose aside right here. I'm going to take some more breaks parts cleaner and spray up in here to try to clean off the upper bolts. The top bolts are really hard to see, but they are pretty much opposite of the bottom ones. There's two on the top and then two on the bottom. Just go on the opposite side and find them, but they're very hard to see from underneath the vehicle.

I'm going to use a long quarter inch drive extension and a 10 millimeter socket and go in from the side here. I'm working on the rearmost top bolt. I think that one's broken free. I'm going to work on the front one. I got that one free. Reach up and grab it. Here's one of the top bolts. You can see how long they are. They go through the power steering pump and then into the block. Pump is now loose. It's only being held in by the bottom bolts, which are pretty much finger tight. You might have to lift up on it. Just thread them out. This will be a bit tricky because the high pressure line is on the other side of it. I'm going to have to unthread this one. I may need to put a wrench in there and now actually unthread it and move it out and the pump all at once. Now it's time to feed the power steering pump out of the engine compartment.

I've got out power steering pump set up on a vice. I've cleaned around this fitting, so there's no garbage or anything that's going to get inside the pump. I'll take an 18 millimeter flare wrench to remove this line. Once you get it pretty loose, you could switch to an 18 millimeter open if you like. The pulley is a little trick. This is why you can't do it in the vehicle. There’s not enough room to get wrench. There it is. Actually no fluid came out of there, that's good. It didn't make a mess.

This bolt here can be removed. You don't need to install it when you're reinstalling the pump. According to the service information, it can be removed and discarded. The only lower bolt we're going to leave is this one. It'll go on there, and of course the two on the top.

Here's our old power steering line out of the vehicle. This is our new one for 1aauto.com. As you can see, it's an exact match in length, same fittings on both ends. This end come with a new Teflon fitting already installed just like the original. It also comes with a new O-ring to go on the end, just like the original. This is the side that goes into the power steering box.

I'll install this little O-ring right now just like the original. Pull this fitting down. Now when you're installing this into the vehicle, because we have to bolt this, or rather thread this into the power steering pump, you don't want to lose this or damage this O-ring. It comes with a plastic cap to put over this so you just leave that on there. While you've maneuvering this into the vehicle, you won't love your ring. You won't get dirt in this end of the line. This will work great in fixing any power steering leaks we've got.

Time to install the new power steering line. Let's try to get it threaded in there. If it helps, you can turn the line to get it started. Take the 18 millimeter open wrench. I'm just feeling it getting tight and I'm seeding that Teflon O-ring. Give it a little maybe quarter turn, and that feels good here and I'm going to stop. Power steering pump out of the vehicle. You can see where the bolt holes are. Two on the top, two in the bottom.

This one here we're no longer going to use. We can omit it according to the service information, so we're only going to put a bolt in here and the two top ones. I'm going to leave this little glove finger that I have zip-tied on here. This is on the low pressure return. I'm going to cut it off when I've got it in the vehicle, but for now I'm going to leave it on there in case there's any fluid in there it doesn't leak everywhere when we're trying to move the pump around. This line is going to come to the front and so I'm just going to spin it around. I'm going to out the bolts right here where I can reach them. I'm going to wiggle the pump up in here on the other side of the oil filter lines.

There are two dowels on the back of the pump. There's one in this bottom hole and one in the top one that I'm going to fit into the engine block. Just move your arms around. That fit in real nice. Take one of the bolts and capture the bottom one. Feed in the top ones. Using a 10 millimeter socket and a long extension for the top bolts. Finished tightening the rear one, and now I'm going to finish tightening the other top one.

Bottom one is hard to reach with a socket ratchet, so I'm using a ratcheting wrench, but first I'm going to tighten it down finger tight, and I'm just going to bring it down tight. Next step will be to route your line to the top of the power steering box.

Install the power steering pressure line into the top of the power steering box. You really can't see the hole that it needs to go into, but here's the yellow can I put in here to protect the O-ring while I was installing it. I'm going to pull the yellow cap off. Make sure your O-ring is still in place. Feed this into the opening. Might have to wiggle the line around a little bit to get it to fit right. I'm just going to thread it in by hand to get it started.

With the thread started by hand, I'm going to take a 14 millimeter line wrench and start to tighten it down. Just have to move the hand a little bit, kind of swing the wrench through the fan blades. I'm going to cut off the rubber glove finger I put over the return hose nipple on the power steering pump. I'm trying to reach up with some side cutters. Might be easier if I spin. Does it tie around to the other side? Okay. Pull that little latex piece off. Reach in and put the line back on. Slip it right over.

I'll get my other pliers and install the clamp. There it is. Okay, the clamp is in place. Take our drive belt. I'm going to feed it down though the idler pulley and the tensioner. I'm trying to get it around the A/C pulley first. I'm going to take half of this belt, loop it around our fan, and then I'm going to go down and around the crank pulley. Now I've got it looped around the power steering pump pulley. With the belt routed, it goes down around the A/C compressor, up through the idler tensioner, down and around the crankshaft, up and over the fan, down and around the power steering pump and then the very last thing will be the alternator on the top because I can reach it. I'm going to relieve the tension from the auto tensioner and pull the belt up over the alternator pulley.

Using the half inch breaker bar, out it into the half inch opening in the auto tensioner, pull it to the driver side of the vehicle. I'm making sure that I've got all the belts on the pulleys. Pull the breaker bar out. The belt is installed.

We're going to reinstall the intake tube. Push that over the throttle body. Plug in the connector that was over here. Push this down into the rubber holders. Reinstall this connector. Reattach the vent hose here. Use an eight millimeter socket or a flat-bladed screwdriver to tighten to the hose clamp. Fix the little vacuum intake box into here. Going to reinstall the cover. Goes over the throttle body. Reinstall the 10 millimeter bolts with a 10 millimeter socket ratchet.

Refill the power steering fluid reservoir with the approved power steering fluid to the max fill level. Use the funnel. You're going to start the truck up, move the wheel to the right and the left repeatedly till any power steering line goes away and the air is bled from the system. Check the fluid level in the reservoir. You may need to add more to bring it up to the max fill level. Then replace the cap and the install is complete.
