How to Replace Power Steering Oil Cooler 2000-04 GMC Yukon

All right, we're gonna take some pliers and take this clamp off right here. This is on the top of the steering box, and it's a good idea to have a drain bucket underneath in case any fluid comes out. And there we go. Pop that off. We're gonna do the same with the hose that goes to the power steering pump. Just take that clamp, slide it back, and slide it off.

All right, let's remove this panel. I'm gonna use a trim tool, take these clips out. Take this panel off. Take this bolt out, use a 10-millimeter socket. And there's four of these twist retainers. Just take a Phillips-head screwdriver and just twist it about a quarter of a turn. And there's another one down here underneath, and two over here as well. And just grab the trim over on the side, you're just gonna pull it forward, just like that. It's clipped in right there on the sides. Do the same for the other side. And it just slides right off.

All right. This vehicle has an aftermarket cooler. Normally, it would be bolted right here and right here. You'd take those bolts out. This has some wire ties. Just cut these wire ties and just slide the hoses out.

Just like that. Take the new cooler, start feeding the hose where the old lines came out. And you might have to grab them from the inside while you're trying to feed these in. Just be careful when you twist it. You don't wanna mess up the condenser. Get this under the cable, the hood cable, and line this up.

All right, so it's gonna line up over here, and we have to take this bolt out here. Use a 10-millimeter socket. Put the bolt back in, and put a new bolt in down here, and tighten them down. All right, take the grille and line it up. Get this lined up on the side. And just twist these. There's four of them. And take this bolt, get that started. And tighten it down. And put this cover back on. And take all the pushpins, put all the pushpins back in.

Take these hoses. The shorter one is gonna go to the steering gear itself. Put that one on first. Then you can a 7-millimeter socket and just tighten that up. Tighten up the worm clamp. And take the other hose. It's gonna go on the pump right there. Then we can do the same, tighten that up with a 7-millimeter socket or a screwdriver.

After you're done, you're gonna wanna check the transmission fluid level. Start the vehicle, let it run. Pull this dipstick out, wipe it off. And there's two areas right here. This is the hashmarks where the fluid level should be when it's hot, and when it's cold, should be down here. You can top off the fluid with the appropriate fluid - get that information from your owner's manual - and adjust accordingly.
