How to Install a Transmission Cooler on a 2017 GMC Canyon


Speaker 1: Today in our 2017 GMC Canyon, we're gonna be installing Derale's 8,000 Series Transmission Cooler Kit, part number D13503. In conjunction with that, we'll be using Derale's Snap In Radiator Adaptor for GM vehicles, part number D13035.And this is what our Transmission Cooler's gonna look like when it's installed. We have our fascia removed to make it easier to see. It can be mounted in any location you like, but this is the closest location to where you hook up your lines.This auxiliary cooler is gonna help keep your transmission fluid at normal, lower operating temperatures. So when you're hauling heavy loads, and putting more stress on your transmission, that fluid temperature's not gonna rise up and cause potential transmission damage. It's gonna keep that temperature more regulated, to it'll be a normal operating temperature even under the most stressful conditions.

This is gonna work with your existing transmission cooler. It hooks right in line with it on the return side, to provide additional amount of cooling.We'll begin our installation here at the front of the vehicle. Under the hood we're gonna need to remove this top plate here, by removing several push pins.To remove the push pin, you'll slide your flat bladed screw driver or trim pan remover tool, pop up the center, and then the entire pin will pop out. We'll do the same thing for the rest of our push pins. Now that all the pins are removed, you just lift the panel off set it aside.

Underneath that panel you'll find some torque screws that we'll need to remove. There's a total of six, three on each side. Use a T15 torque socket to remove those.We're gonna remove six torque screws from inside our wheel well. You'll have three down the side and three along the bottom. You may need to turn the wheel to get access to these.

Here on the inside you'll find three bolts that we'll need to remove using a seven millimeter socket.Then you'll remove the one bolt located at the bottom corner towards the inside, just behind your under liner. You can also use a seven millimeter socket for that.We'll now need to remove the four bolts that hold on our under shield. We use a 15 millimeter socket to remove those. It'll be two towards the rear, and two towards the front. And we can set this aside.

Underneath our panel you'll find a 10 millimeter bolt towards the front we'll need to remove. And there's one just like this on the other side.We're out in the front of the vehicle, just underneath the grill. We're gonna need to go through the slits using a 10 millimeter socket and extension, to remove two bolts, one on each side, through these openings.We're now ready to remove our fascia. Starting on one side, you'll wanna peel outward on the edge. This comes out and down at the same time. And we're gonna do the same thing on the other side. Then you wanna disconnect any wiring that you may have behind it, such as our fog lights that we have here. You'll press in on the tab and just pull rearward. There's one of those on each side if you have the fog lights. And now we'll set our fascia aside where it won't get damaged.We now need to remove the air shutters in front of our condenser and radiator. You'll remove the trim piece first, located here. If you look around, you'll see some pins located here and on top. We'll need to remove all those pins. And now we'll set this aside.We'll now need to remove all the 10 millimeter bolts that go around our panel here. There's a total of eight. We'll need to get our electrical wiring off so we can pull our panel off. So you can pinch it here at the top, pull it down. It's also attached here with a push pin, so you'll just wanna get behind that with your trim panel remover and pull it out.We'll now remove the air deflector off, down here. There's gonna be three push pins on the top. And our last bolt's gonna behind that panel, just here.We'll now lift up on the tabs located here, pull outward. There's one on this side as well, and our panel will fall forward. We'll need to disconnect the electrical connector located over here. Push out on the locking tab, press in on the lever to release it. Then we'll need to pry it off using our trim panel removal tool.We'll now prepare our transmission cooler for installation.u wanna remove the caps off of each end of our cooler. And we'll take the hose that comes in the kit, and we're gonna slide one end on our cooler. It's a little difficult to get on. You can use some lubrication. Just using a little silicon spray, and that'll help the hose slide on easier. You'll take the other end of your hose, and that's gonna go right on the other side, making a loop.We'll now install our hose clamps. You use a 1/4 inch socket. We'll loosen the clamp up, we'll slide it over our hose, and then we'll tighten it back down. I like to position the hose clamp so it's facing in this direction, away from our back piece, so we know that the clamp end's not gonna get in the way of anything. You also wanna make sure that you're not down at the bottom of the hose, and you're also below the bulging area where it's slid over the end. We'll do this on each side.We'll now take the mounting clips that come with it. You're gonna take the button end, that's gonna be towards the front of the radiator. We're gonna slide it through our bracket here. And on the backside, we'll take the foam piece that comes with it, we're gonna peel back the adhesive, that's going to poke through with the adhesive side facing towards the radiator. We're gonna slide it down and stick it up against the back. We'll repeat that for the remaining three outer holes. Now with all four in place, we can mount our transmission cooler onto our condenser and radiator here. We're gonna be putting it in this upper passenger side area because our hose for our transmission line that we're gonna tap into, is located here on this passenger side. That way we'll know that we have enough length of house to do what we're trying to achieve.So we'll line it up and pass it on through. When you're doing this, you wanna be careful not to puncture anything. So if you feel any excessive resistance, you wanna stop and change your spot. It's probably better not to go all the way through, so you've got yourself some room to work with. Just kinda line that up so it looks like you're about straight, and just repeat that process. Now that they're all pushed through, we're gonna need to put our locking nuts on the other side. You wanna make sure that the Derale name is facing away when you slide 'em on. So they'll go on in this direction. They simply just push into place. And you'll wanna work that all the way down, so it's flush up against the radiator. You'll repeat this for the remaining three.When you're cutting 'em off, you wanna cut it off as close to the pin you pushed on as possible, so that way the fan won't contact them and cause any noise. You're gonna do this for each one.We'll now take the looped line that we have on our transmission cooler, we'll cut it to length, so there'll be two pieces coming off of it, and it's gonna connect in line with our transmission line here. This is the return side of our line. If you we're curious how I knew that this was the return side, if you just operate your vehicle and let it run, and feel both this transmission line and the other one, they're both located down there, it's a little bit easier to grab them. The hotter line is gonna be the line coming from your transmission to your radiator, and the cooler line is gonna be the one going from the radiator returning back to the transmission.You can see this panel here blocking out entry point, so we're just gonna trim this panel. So I'm just gonna start by pushing it out so we can make our trim. So we're just gonna make a diagonal cut in this opening here, down to this opening here. Now we've got an access point to get our hoses run.Before I cut my hose, I wanna make sure I've got enough length. So I'm just gonna slide it on through, over to where our other line is on our radiator. And now we've got that ran through, we're just gonna tuck it out of the way for now, and we'll disconnect our transmission line. To disconnect the line, you'll first pull back the plastic covering. So that just pops off, and you can slide that back. And there's gonna be a small clip on there. Now it's very important when removing this clip, that you keep it covered with your hand. So I've got my pick started behind the clip, now I'm gonna place my hand over it because once this clip fully releases, it can shoot out of there, and you don't wanna lose this clip. You have to have it. So I'm gonna get my hand in place over the clip. Once you've got your clip off, this is what it'll look like, so if it shoots off, this is what the clip that you're trying to find.Here's our GM adaptor that's going to go into our radiator coming from our hose. So we're gonna do a quick test fit just to make sure that everything's gonna line up properly. This just pops out, hold up real quick just to make sure you've got the right one. Our look to match up. So we're gonna stick our hose back in so we don't lose too much fluid. Just a little bit ran out there. We'll now cut our lines to the appropriate length. So one line's gonna need to attach to our adaptor, and go into the radiator. The other line is gonna slip over our existing transmission line, and we'll clamp it down with a clamp.So we're gonna cut one side slightly longer than the other, since one just needs to wrap around into there. And the other's gonna be connected to the hose there. So not too much longer, just a little bit. About like that. And when you're cutting this, you do wanna be sure you use a hose cutter. This way, you cut it clean and square. We'll start by installing our adaptor into our shorter hose. So again you're gonna wanna use some lubricant to make the installation easier.After you push in, you don't wanna go all the way to the edge here, because this does have to seat inside of your radiator, and the clip goes between the radiator fitting and the back side of this fitting. That's what holds it in and keeps it from popping out. So we got it out about roughly a 1/2 inch there. We'll install our hose clip on it now. I'm gonna install it in this orientation. It really doesn't matter how you install it, this one just looks like it'll give me the most room to work with. We'll tighten it down with our 1/4 inch socket. Since this adapter is made of plastic, you don't want to overdo it. So we're just gonna get it nice and snug. Next we'll be taking the line out of our radiator, and this needs to slip in right behind it. You wanna try and do this as quickly as possible so you don't lose too much fluid.It's not a bad idea to place a drip pan down below to catch any fluid that leaks down. So we're gonna quickly pull our line out and slide our new one in. The clip just pushes right back on. It's important that these ears seat down inside the grooves. There's gonna be a total of four grooves located on that clip. You wanna make sure that each of these edges go inside of a groove. And now it's snapped in place just like that. You can see it's completely flush, and we cannot pull our hose out.Now the other side of our line is going to connect to our original transmission hose. So we're gonna lubricate the ends here, and slip our hose over the line. We'll now take our hose clamp, we'll slide it over our transmission line, and we'll tighten it down.I'm now gonna use a zip tie to hold this line here in place. I'm gonna zip tie it right to the line harness here. This'll keep our line in place and out of the way from contacting any moving objects such as our belts and pulleys there, or our fan's route. Now you wanna check all of your other lines, and zip tie those if necessary.And now to test it out and make sure you don't have an leaks. This is a good time to start your vehicle and check your lines. Now with everything running, and there's no leaks, you can reinstall the rest of your fascia in reverse order that we took it off. And with everything back in place, we're ready to hit the road.And that completes our installation of Derale's 8,000 series Transmission Cooler kit on our 2017 GMC Canyon.

David is a pretty cool guy and is great at what he does. If you live near the Wentzville, Missouri area or you want to make a roadtrip you can reach out to our customer service team at 800-298-8924 to speak with them about setting up an install. Otherwise if you plan on trying to do the install yourself I hope this video helps out!

Hi there, I am going to install this on a 2018 gmc sierra. Is removal of the front grill the same as above on the GMC canyon video?? Do you have a video using a Sierra? thanks

We don't have an install video available showing the Derale Transmission Cooler # D13503 being installed on your Sierra, however the process should indeed be really similar to what's shown above on the Canyon.
