If you like to keep your JK's engine cool, then you might want to look into your radiator. Today on CJ Off-Road, we're gonna be ditching our factory radiator for this upgraded Mishimoto.

This Mishimoto radiator is a direct-fit replacement for all 2007 to 2018 JK Wranglers equipped with either a 3.8 liter or a 3.6 liter engine. This radiator's going to be 60% thicker than the factory radiator, allowing for much more cooling properties, and to give you a nice clean look. This radiator is constructed out of aluminum and then hand TIG welded to ensure durability for a long time. It includes a 1.3 bar high-pressure radiator cap, which is going to effectively raise the boiling point of the engine coolant, providing a safer and more effective system than the factory JK cooling system. It includes a magnetic drain plug to ensure that any metallic debris or fragments in your cooling system are going to easily be collected and removed harmlessly.

Now our JK has been running hot for quite some time now, so we're gonna get it replaced, and thrown into our 2008 JK Wrangler. Tools we need for this installation: quarter inch ratchet, seven millimeter socket, eight millimeter socket, ten millimeter socket, small extension, ten millimeter ratchet wrench, trim removal tool, a pair of pliers, and a pan, or something to catch the coolant.

Before you start this install, disconnect the negative battery cable on your Jeep. That's gonna protect all your electrical systems, and keep you safe in the event that something shorts out.

Use a ten millimeter socket to get this pulled off, just to loosen it up a little bit. And it should pull right out after you get it nice and loose. Set this out of the way, and make sure it doesn't hit the positive battery terminal; just tuck it underneath there.

Make sure you get a drain pan because this is the messy part. We're gonna drain our radiator of all the coolant by twisting this knob. It's up here underneath the grill. Grab it with a pair of pliers, and be easy, it is plastic. Turn it counterclockwise. We're just gonna let it drain out.

Now that you have your radiator completely drained of the coolant, we can now remove the factory airbox. I'm gonna go around and pull these four clips off, just like that, and then we'll get to removing it.

Disconnect this PCV hose in the back, pull the top of the airbox off, set it aside like so. Pull this bottom section of the airbox off. There's going to be two grommets that it goes into, just pull it straight up. It sits in a rubber grommet. It'll just give you a little bit of resistance, and it'll pull right out. Pull these four pushpins off the radiator shroud on the top.

Once you have the last one popped off, pull the shroud towards the Jeep, and you can pop it off. You can now remove this coolant overflow hose off of the top of the radiator just by pulling on it. Make sure there's nothing in there.

Once that's disconnected, honestly, I'm just going to put in the top of the overflow tank, that way if anything has to come out, it'll go right into there, and we can move on to getting this upper radiator hose off.

Before we can knock out that upper radiator hose, we're gonna disconnect the fan shroud plug right here by depressing on the back of it, and pulling it straight out. Disconnect the upper radiator hose by depressing on this clamp with a pair of pliers, and just slowly twist it back. Be careful, there is still fluid in there. I just tucked it behind one of these AC vents, one of the these AC hoses back here, just to keep it, that way that fluid doesn't leak out.

The coolant overflow tank is the next thing to be pulled out. Simply pull up on it a little bit, helps if you can kind of reach in there a little bit awkward. There's a little slot at the top, it'll pop right out of, and pull right up, and you can set this out of the way for now.

Now this is a little bit awkward to get to, but there are three pushpins underneath the lower radiator shroud. Use that same trim removal tool you used up top, and just get them pulled off. There's two eight millimeter bolts that hold on this fan shroud, so use an eight millimeter socket, and get them removed. Make sure you save these for later. You're gonna be reinstalling this fan shroud onto the new Mishimoto radiator. All right, and repeat the same process on the other side. Go ahead and pull the fan shroud out.

The next step of this installation is to remove your grill. Now to do this, you have to remove the six clips at the top, and disconnect the turn signals, and just pull it out towards you. It's a really simple process. Just use a trim removal tool along the top. Pull out the six pins, and on the back of the turn signals, you just turn them counterclockwise, and pull them straight out.

Okay. With the grill removed, we can now pull off the four eight millimeter bolts that are at each corner of this AC condenser in the front, and get that removed. I'm gonna use an eight millimeter ratchet wrench to get this done. Make sure that you save the hardware.

Next, you can remove the lower radiator hose by depressing that same clamp, like you did for the upper, just giving it a little pull back. Make sure that you have your drain pan underneath here because there's going to be coolant inside of it. There are going to be two clips on the side here for this radiator shroud. Pull those off with the trim removal tool. Repeat the same process on other side. We're going to disconnect the lower shroud by pulling two more pop pins. There's one on this side, and one on that side. Trim removal tool's gonna be your best bet. Get under there, pull it downwards. There's two ten millimeter bolts that hold this onto the upper shroud. Go ahead and get those removed. On the other side, I'm gonna use an extension to make it a little bit easier, same ten millimeter socket to get a bolt off.

On the driver's side of the radiator, there's a bracket that actually holds on the AC condenser lines. In between there there's an eight millimeter bolt that has to be removed, so you can get that bracket off of the radiator. Very hard to see, but you can get in there with a simple quarter inch ratchet, and an eight millimeter socket.

With everything disconnected, it's now the long awaited time to pull out this old radiator and get rid of it. Here's a side-by-side comparison of the factory radiator versus the new Mishimoto one. As you can see, the Mishimoto one on the right is much newer. It's all aluminum and TIG welded. It's a lot thicker, close to 60% thicker than the factory radiator, and it's not as beat up. Honestly, our factory radiator has seen years of abuse on the trail, and on the highway, so it was well worth the time to pull this out. We're gonna get started putting our new Mishimoto radiator into its place, and show you how that works.

Now it's time to install the new Mishimoto radiator. Drop it into the location, watch all your wires in that. Then install the two ten millimeter bolts that hold it onto the top support. With the radiator mounted up loosely, with the hardware, we're now going to install the AC condenser, use the included hardware with the Mishimoto radiator, and use the top stud. We're gonna start with the passenger side here, get it mocked up, and then get the other side, and all of them tightened down. These are going to use a ten millimeter socket to get them tightened down. I'm gonna use this ratchet wrench and get it done.

Down on the side of the radiator, there's a small hole for the AC condenser lines to go onto. Use the included hardware to get that bolt started. It's really tricky to see, but use the ten millimeter socket, and you'll get it started up. Now that the AC condenser is fully tight, we're gonna get these two upper bolts tightened down into the upper radiator support, using that same ten millimeter ratchet wrench.

While we were doing this Mishimoto radiator install, we figured it'd be a great time to upgrade the radiator hoses, so Mishimoto hooked us up with a set of these blue silicone radiator hoses for our 2008 Jeep JK Wrangler. These are going to be available for the 3.8 liter and the 3.5 liter engines. So if you have a newer Jeep, you can get a nice set of hoses, and no you don't have to get them in blue. So if you want a different color, we've got red, black, there's olive drab, and even camo to put underneath your Jeep, to give it that custom touch, and make it run a whole lot cooler. Let's get these installed now.

Let's get rid of this factory lower hose. We're gonna have to go underneath. It's right next to the engine, you can't see where that clip is. I'm just gonna use a pair of pliers to see if I can get that connection off, get this yanked. Let's slide this new Mishimoto lower radiator hose into place, then slide a band clamp provided. We'll get another band clamp on, and then attach this to our Mishimoto radiator up top here. Make sure it's fully seated on, clamp over the bulge, and right behind it. We'll get them tightened up with a seven millimeter socket, or a flathead will do the trick too. Tighten both band clamps. I'm gonna get this one tightened by the engine right here up.

Now that you have that lower radiator hose installed and fully tightened, we can install the fan shroud. Use the provided hardware to go into the threaded studs. Tighten them up with a ten millimeter socket. Plug it back in, and you'll hear a click. Reinstall the overflow tank onto the fan shroud. Push the overflow line onto the top of the Mishimoto radiator. Clip it back under here. Put the cap back on. Remove the upper radiator hose, get that clamp out of the way. Let's get it pulled off. Install the Mishimoto upper radiator hose. Get it mocked up into the proper location, then we'll slide a clamp over it, and get that tightened up. Slide one of the band clamps over. We'll use a seven millimeter socket to get that tightened up. Put another clamp over this end, get it onto the radiator. Make sure it's all the way up, a little bulge here, make sure it's over that. We'll get it tightened down, once again with that seven millimeter socket.

We're gonna reinstall this piece here. We honestly debated on not putting it on, but if you're gonna lean in and out to work on your engine bay, this is gonna get really hot if it's been running. Leaning over it, you're gonna burn yourself, so we're gonna put this back on, even though it covers up all that new Mishimoto goodness. Once you have them into place, push these pushpins down.

After that's all installed, it's now time to put your airbox back in. First, put this lower section in, back into the grommets. Then we'll get this top piece back on, and put those clips back into place. Attach your PCV hose to the airbox. Put the grill back into place. Now we'll reconnect the battery.

Well, it is a little bit hard to see, but we just wrapped up the Mishimoto radiator install on our JK Wrangler. We have it filled up with coolant that's recommended for our Jeep, and everything is running smoothly. We started up the Jeep, and turned on the heat, that way it flushes and cycles all the through.

This install takes about five hours, and you can do it in your driveway with simple hand tools. You can find this Mishimoto radiator, as well as the hoses, and a lot of other parts for your JK, right here at CJPonyParts.com.
