How to Install the Derale Series 8000 Plate-Fin Transmission Cooler Kit on a 2018 Nissan Frontier


Hey everybody, Ryan here at etrailer. Today on our 2018 Nissan Frontier, we're going to be taking a look at and showing you how to install the Derale Series 8000 Plate-Fin Transmission Cooler. this is what the transmission cooler is going to look like on the front of your Nissan. Now, in our case, we just left the front of the grill off, that way we could actually see what we're talking about here. A lot of our midsize truck customers use their vehicles to do quite a bit of towing. Whenever you're doing that, that can put some extra wear and tear on your transmission.

Well, a lot of them want a way to have a little bit more peace of mind and reliability knowing that their transmission is going to last a lot longer. And that's where the additional transmission cooler comes into play. It's really going to increase the performance and help prolong the life of the factory transmission.So whenever you're towing something, your transmission is going to have to work harder. And whenever that happens, the fluid temperature inside actually rises. And whenever that happens, it's going to break down the transmissions internal components and wear them down faster.

And that can cause complete failure, slippage, erratic shifting, multiple different issues. So with the extra cooler, it's going to help bring that transmission fluid temperature down and eliminating a lot of those problems. Derale transmission cooler is actually going to work in conjunction with the Frontier's factory cooler. So what's going to happen is, warm fluid is going to come through the line into the Derale transmission cooler, and it's going to run over to the other side. And all of these fins are more or less heat exchangers.

So that way, whenever cold oncoming air passes through them fins, it's going to dissipate that heat or draw that heat out of the fluid, making it cooler.So that cooler fluid will go to the other side, back down. Then it's actually going to do the same thing through the factory cooler. That already cooled fluid is going to pass through everything, get even colder and then go back into the transmission. So a lot of people are going to want to know how big the cooler is, especially to figure out where you can mount it. Now, this one's pretty decent size and it fits really with no issues at all on our Frontier.

But that being said, from side to side, it's going to be 11 inches wide, it's going to be seven and one quarter of an inch tall. And the thickness of it or the depth is going to be seven eighths of an inch. Now to compare this one to another different style of cooler, which is the 2-fin, I'm definitely going to have to say, I prefer the plate-fin like we have here today. That's for a few different reasons.This one's almost going to be more of a factory style component. This will be much more reliable and well-built. It's going to be much harder to damage all of the fins and overall just lasts a lot longer. The tube-fin style, as opposed to just having the plates that run from side to side, there's actually going to be some tubes that run along this way and they're not going to be enclosed. And they're just really easy to get beat up. So overall, this is this a good precautionary measure you can take to save potential headache in the future and be a little bit safer as you tow down the road. Now as far as the installation goes, believe it or not, it is really straightforward and easy to do. Once we get the grill out of the way, we're going to have a ton of room to work with and more or less consists of mounting this up and connecting a few lines. Speaking of which, let's go ahead and do that together now.To begin our install, we're going to be working here at the front of our truck. You're going to want to pop the hood. And we're actually going to remove the center section here of our grill. And to do that, we're going to have six plastic push pin fasteners here along this top edge. To get these out, we can just take a small flat head screwdriver. We're going to pry underneath the head of it. Then you can pry up on the base and then pop it out. So we'll go ahead and get all these removed. What we need to do now, if we come down to the bottom of our grill, we're going to have six plastic tabs just like this, and we're going to have to pop those free. So the way to do that is if you get underneath the tab and push up on it, that'll pop it free. And I like to work from one end to the other.So work from one side to the other. And when you push up on it with your finger, you can grab the grill and pull it out. That'll start to free it. We can pop our grill out and set it to the side. Now to give you a better idea of how these tabs work. You can see that little portion there, when you're pushing up on it and pulling the girl out that'll release it. Now we can prepare our transmission cooler. So what we're going to do is put one line on one side. That way we can find a spot to mount this and make sure we have enough line to get everything ran. Go ahead and pull one of the caps off and we'll take our hose. What I like to do, I've just got a little cup of transmission fluid and I dunk the end in it to help lubricate it. Let me just slide that onto the barbed fitting here on our cooler.With one end over hose on the transmission cooler, we can grab one of the included hose plants, and slide that over. You can go ahead and tighten that down. So now we can mock our cooler up in the spot that I think we're going to go with is right here in this area. So we can take our line. And this has got to get connected over here to our factory cooler, here at this bottom fitting. So if you just roughly run our line over there, looks like it's only going to give us about another foot to work with. So what we're going to have to do is grab some extra hose and get it connected to the other side of our cooler. Now that we know how much we have to work with.So I went ahead and grabbed about another three or four foot of line. If you need some extra, you can find it here at etrailer. So I'm going to take this end and put it on the other side of our cooler the same way, lubricate it a little bit with some transmission fluid, push it on. Once I have it all the way on the fitting, I can come back with another hose clamp and tighten it down.Now we can go ahead and mount our cooler up. Just want to line it up with our core support, get it nice and straight, and then I'll secure it using some self-tapping screws.Now we can hook up this hose from our new mission cooler over to our factory cooler. So what I'm going to do is just roughly run the line over to the fitting. That way I can just mark it out and cut off that extra. What I do now is just more or less prepare this to get connected, take a hose clamp, and just slide that over. I can just let this hang out for now. If we come down here, we're going to have to take this manufacturers factory clamp off. So we'll grab a pair of pliers, you squeeze these two ends together and work it back. I'm going to pull this off, and then quickly slide our new mission cooler hose onto it. That way we don't have to worry about making a big mess. So I'll lubricate it a little bit, that way we're ready to go. Carefully, pull this off, slide that on. We'll take her hose clamp and tighten it down.Now we can grab the coupler that comes with our kit and we're going to put one end of it into this factory hose here. We'll go ahead and lubricate it a little bit. This'll just push right in. We'll work it down till we're about halfway through. So you want the other half of the coupler to be exposed because this'll get connected to the new transmission cooler line. So about like that, then we're just going to take that factory clamp and run it back onto the end of the hook. So now we can grab the other hose from our new transmission cooler, the other side of it. And I'll run this over to our coupler and cut it to length. And then we can just take this end, slide it over the coupler and pair the two together. Before you slide that on, don't forget to put on your hose clamp. We have our hose clamp, line it up and tighten it down.So I went ahead and just used a handful of zip ties to just help clean up our install look and secure all the hose. And then what you're going to want to do is start your Nissan, let it run for a while, get it up to operating temperature and inspect all of the connection points for any leaks. Once you verify that there is no leaks, it's not a bad idea to go to your dealer and have them top off your transmission fluid if you lost any during the installation process. Now that we've verified we have no leaks and everything's working properly, we can go ahead and reinstall our grill. And that'll finish up our look at and our installation of the Derale Series 8000 Plate-Fin Transmission Cooler on our 2018 Nissan Frontier.
