    Video Review & Installation

    This Mishimoto aluminum radiator for the '07 and up JKs is for those of you looking to replace your factory radiator. Because it's broken, it's just clogged up, it's got a leak, and you want something that is built much stronger than a factory radiator, and that is also going to have a lifetime warranty. This is a very high-end, very well-built radiator. Now, if your cooling system is performing properly as is, I don't think that this is going to provide a whole lot of benefit to you from a cooling standpoint. However, as I said, if you have a busted factory one and you want to go with an upgrade, that's where this is going to come into play. Now, a factory radiator is going to be about half the cost of this one. Of course, it's not going to have that lifetime warranty and it's not going to be all aluminum like this, and this is definitely not the most expensive radiator out there either. So it is going to be a middle of the road price, but also a lot better quality than a factory one. As it says in the name, this is aluminum, and it is 100% brazed aluminum. This is also going to have an inch and a half-thick core for optimum cooling. It comes with a magnetic drain plug. In case you do have any sort of issue in your cooling system, that's going to help to capture any junk that might be floating around. Of course, you are going to get your radiator cap along with this. The whole thing is TIG welded. As I said, quality, quality, quality. This is very, very well-built. But it would have to be, in order to pay twice what a factory radiator costs. Getting this installed is going to be a one out of three-wrench installation. However, it may take you around two hours to get it done, because there is a good bit of removal and disassembly to do to get your old radiator out of the way. Now, the first step is going to be removing the grille and removing the frame cover from your Jeep. You can also remove the upper and lower radiator shrouds. At some point in the installation, you're also going to have to remove the airbox, as well as the air inlet tube from your Jeep. Remove that ambient air temperature sensor, so you can make sure you don't break that or pull the wires taut. You're going to, of course, have to drain the fluid out of your radiator, unbolt the A/C condenser and move it out of the way, and finally, remove the whole radiator with the fan assembly attached to it out of the vehicle. From there, the whole thing just happens in reverse. Unbolt the fan assembly. Bolt it to your new radiator. Set it in place. Bolt everything back up. Of course, fill this up with fluid after attaching all of your lines, check for leaks, and burp all of the air out of the system to ensure everything is going to work properly. One tried and true way to get all of the air out of the system is to park the Jeep on a hill with the nose facing up, remove the radiator cap, and just let the Jeep run. When the thermostat opens up, all the air will be pushed out of the top of the radiator, and you won't have any air left in the system. This radiator will run you right around $400 and as I said before, it's certainly not the most expensive. We do have a radiator on the website that is more than double that. However, a factory replacement is going to be about half this cost. Now, with this you are getting the all-aluminum construction and the lifetime warranty. Ideally, this would be the last radiator that you would have to buy for your JK. Where if you get something less expensive and you do have some damage to it or it fails on you, you may have to go ahead and replace it again. So it really depends on where you want to spend your money and what you're looking to get out of a radiator. Again, I don't think that you're going to get a ton of additional cooling out of this radiator. If your cooling system is working properly as is, this isn't going to boost it dramatically. However, if your cooling system isn't working properly because of a clogged-up radiator, of course, this is going to have a big impact on your cooling. Overall, I think that you are getting a lot of quality from this radiator. If you're looking for something that has a lifetime warranty and that is an all-aluminum replacement, I don't think this is a bad buy. So if you're looking for an all-aluminum replacement radiator, I definitely recommend taking a look at this Mishimoto aluminum radiator that you can find right here at
