How to Install a Derale Series 8000 Plate-Fin Transmission Cooler Kit on a 2011 Chevrolet Express V


Ryan: How's it going Ryan here @etrailer.com. Today, on our 2011 Chevrolet Express van, we're going to be taking a look at and showing you how to install the Derale 8000 plate-fin transmission cooler kit. Many of our Express van customers, use their vans as work vehicles, and that usually entails towing heavy trailers that are having a lot of weight inside, which can put some strain and heat into your transmission whereas with the cooler is going to help eliminate.It's going to help lower those transmission temperatures, prolonging the life of it, and making it more reliable. And that's going to put you and your passengers mind at ease, knowing that your transmission is running cool. You're not going to have to worry about breaking down or overheating. On the way, it's essentially going to work, this is going to act as a heat exchanger.

So hot fluid is going to come in through one side and transfer over to the other and back through, down to your transmission, while these fans are going to disperse the heat from fresh air flowing over them.Now, what sets this one apart from some of the other styles, such as the tube fin, is that this one is the plate-fin. so it's going to have these little plates that run through that, carry the fluid from one side to the other, as opposed to a tube fin, which is going to have tubes that run through like that. Now, in my opinion, the advantage with these is they're much more sturdy and solid and all the fins don't get bent up near as easily.Something I do want to point out more often than not, you are going to have to pick up a few small items to make your install a lot easier, such as, an extra length of hose and adapter. Now the cooler itself is going to be 11 inches wide, seven and one quarter of an inch tall and seven eights of an inch deep. And that's going to be how thick it is.

Even though it looks like a lot of work for moving the grill to get enough for him to get this installed, it's really not all that bad. And it doesn't take up a whole lot of time. Speaking of which, let's go ahead and put the on together now.To begin our installation, we're first going to pop our hood. And then we're going to remove our grill to give us some room to work. You can first take our headlight out, which is held in place by two, 10 millimeter bolts.

Once we have those out and grab our light, we work it out. That's a little tight in here so you might have to sign that perfect angle to get it to slide out. And once we get it so far, what we're going to have to do is disconnect our lights from the back.So we're going to have two lights disconnect and get them off, simply just lift up on these tabs and push down. Let me just set this off to the side. So, now we're going to go ahead and pop out our running lights.

Now here in the corner, it's going to be a white tab that we need to push in that way we can go ahead and pull our light out. So just from the outside of the vehicle, I'll use a flathead kind of put inward pressure on that tab. And we're going to simultaneously hold the light out away from the vehicle.We're able to take that light out, once again, we're going to disconnect the bulbs. What you're going to do is push up on this one, that'll allow us to pop that out, same thing for this one, just push up on that tab and pull them out, we'll set this off to the side. Now the other side was set up the same way. So I just repeated that same process. Now in the center of our grill, we're going to have two 10 millimeter bolts attaching it to the radiator for support. So we'll go ahead and pop both of those out.Now, if you move back over to our running light pockets, if you're on the edge, we're going to have a 10 millimeter bolt. So we'll take that out and then repeat that same process on the other side. Now we're going to be able to release two clips here on our grill. Now, usually you can just use your hands to pop it out. But if it's a little tight, you can just take a flathead screwdriver, just put it behind there, prying outward on it, and it should pop out just like that.Now to completely remove our grill we have two more clips to take off, just like the ones that we did in a moment ago. They're going to be right here straight down. Can be a little tricky to see, I use that same method with my screwdriver to pry it away to release that clip. We'll do the same thing on the other side. Both the clips removed, you can go ahead and take it off. Just to give you a better idea, that's where those clips are and what they look like.Now with the grill out of the way, we can choose a spot to mount our cooler. And that's one of the main questions we get asked. Well, you want to choose a spot that's out in the open and that's going to receive maximum air flow for maximum efficiency. The spot that I'm going to choose is our factory bracket here. And so we're just going to kind of eyeball it, where we'd want to mount it and go from there.Now, before we secure it, what I'm going to do is attach our hose to each end of our cooler. Because it is really tight and it'd just be a lot easier to get those ends on now, as opposed to trying to do it while it's attached to the front of our van. Now I went ahead and put one line on one end of our cooler. And before we put the other end on, you want to make sure to grab two hose clamps and just slide them onto the hose. Now, what I like to do is just take some transmission fluid and coat the end of that fitting to help give it a little lubricant. Because it is a pretty tight fit.Just grab the hose and work it on over that fitting as far up as we can get it. And you just want to get it far enough up that we can easily get a hose clamp on it and we know we're going to have a good connection. So, once you got both ends on, you can just take your hose clamp, hold it in position, and you can just go ahead and snug it down. You don't need to crank down on these, you just want them to get snug. We can go ahead and cut our hose in half. And now we can focus on mounting up our cooler.Now I'm just going to use some self-tapping screws to secure our transmission cooler to the bracket tree. So now what you're going to do and what we went ahead and did, just start up the vehicle and let it run for a while, get up to 10 and then we actually felt these two lines to figure out which one was hotter. We felt that this one was the hotter out of the two. Now that's the line that we're going to tap into to hook up our new transmission fluid. So to tap into it, we're going to have a little black plastic collar here.You can just pull that down and underneath it, it's going to be a really small clip that we're going to need to take out. So if you look at this really small clip, you're going have to get a pick in there to get it popped out. And I kind of get in there behind it. Start to pull it out. Now, when it gets to about this point, these things like to just fly out and they're really difficult to find. So I'm just going to grab a magnet, get a magnet on it, that way if it decides to do that, at least I'll have some chance of it sticking to the magnet.All right. So that's what that little clip is going to look like. We're going to set this off to the side, be sure not to lose it. It's going to protect take that line, just kind of wiggle it and work it out. And I like to have a rag ready because we are going to lose a little bit of transmission fluid, that'll just help prevent it from making a big mess. Now we're going to take this hose and connect it to this line. Now before we do that, I want to take one of the clamps, slide it over the hose, and then we can just push these two together.Now that we got our hose over our line, go ahead and slid the clamp down, you go ahead and snug it down. Now I'm going to be utilizing this adapter that you can find here at etrailer.com that way I can plug this into my other line like so, and then this will just clip into that factory one and it'll make everything a lot easier. So go ahead and put this end in our rubber line first. Now, once we ever fitting on and then go ahead and take another clamp and snug it down. And from here, we can then take our hose with the fitting on it, push it up into place and then re-install that little clip.Once that clip is in, you want to make sure to pull down on that to make sure that it's not going to be able to easily be removed. So we're all good to go there. I went ahead and just used a couple of zip ties to hold our lines secure. As well as using a couple of self-tapping touch screws to secure the bottom of our cooler. Now, since we are adding some more volume, if you will, to our transmission fluid capacity, it is a good idea to go to your local dealership and have them check your fluid and add any if needed.Now, before you put everything back together, it's a good idea to start it up and check for leaks. And so now we can go ahead and take our grill and put it back in place. Once you got the grill resecured, you're going to put everything back in the opposite order that we removed it. And that'll finish up our look at and our installation of the Derale 8000 plate-fin transmission cooler kit on our 2011 Chevrolet Express van.
