    Review & Install Video

    Hey, guys, Stephanie with here with my review of the Mishimoto performance aluminum radiator, available for your S550 GT Mustang.This aluminum rad from Mishimoto is gonna be for any automatic or manual GT owner that's looking to upgrade their cooling capabilities, no matter what plans they have for their car, whether they're looking for more performance for the street, the strip, the track, or a combo of all of them. This rad is an upgrade over the factory radiator for sure, even the already upgraded performance pack rad, and for a few reasons. I'll start with the fact that it has a three row core. The three row core and the aluminum construction mean more tubes and fin surface area. So this will be able to dissipate heat quickly. It'll increase cooling efficiency and be lightweight all at the same time. And I'll discuss just how much more tube and fin surface area that you're seeing with this rad in a second.A few more things that I like about this radiator, it comes with this precut rubber trim seal, which is actually gonna divert air to the rad. It also comes with Mishimoto's limited lifetime warranty for some added comfort and a magnetic drain plug too, which I think is just a nice thing to have.Even if this rad has that bigger three row core, it's still a direct fit product. So it's gonna fit fine in the factory location. And as far as performance, the three row core and the greater surface area are a big improvement over the factory rad, even the performance pack rad. Mishimoto boasts a 77% increase over the performance pack rad. Thanks to a 26% increase in coolant surface area and a 55% increase in air surface area. And the gains over the regular stock rad are even larger.When it comes to price, this radiator's gonna cost between $500 and $600. Now, this isn't what I consider breaking the bank, especially considering the performance upgrade that you're getting here.One other thing that you might wanna consider is picking up a new set of silicone hoses while you're doing this. If you wanted to do that, you're gonna be looking at spending a little over $100 more for everything. And you also have to keep in mind that you should refill a fresh coolant after this is installed. So you should pick that up while you're at it.And speaking of the install, you're probably looking at about two hours, since you'll have to drain and remove your old rad first and then drop the new one in. I'll say that it's a one out of three wrenches on the scale. But the most annoying part will be the drain and refill process. This process isn't hard, but it can be a pain. The job can be done on jack stands if you don't have access to a lift. But as usual, a lift would make things a lot easier. You need a handful of tools, but nothing out of the ordinary. And of course, just make sure you have a catch can to drain into.So, of course, you've got to drain your stock rad before pulling it out. And the flush pan will have to come off in order to get to the drain plug. The rad hoses will need to be disconnected too, and you'll have to drain some from those as well. Removing the rad itself isn't hard. It's just a matter of pulling the cover in the overflow tank and your aftermarket cold air intake if you have one.The rad comes out with just a few bolts, so it doesn't get much easier there. You have to transfer over your fan to your new rad as well as your rubber mounts, your metal clips, and your hoses too. The new one goes in the same way that the old one came out. You can bolt it down and get your hoses attached and your overflow tank back in place. And lastly, you'll just to refill.So this aluminum radiator from Mishimoto fits both automatic and manual GT Mustangs and is a pretty big upgrade over the factory radiator, even if you have a performance pack car. There's more fin surface area and more tubes, which means a much higher cooling capability. You can check this thing out more online if you'd like to. And for all things Mustang, keep it right here at

    Keep Your Cool. You love every opportunity to experience your S550 Mustang's power. After all, that's what it was built for. But your pedal to the floor laps at the track can significantly raise engine temperatures, resulting in loss of power and even possible damage. Maintaining proper temperatures is critical to an engine's efficiency and longevity. Do your engine a favor and upgrade from the stock GT/GT350 radiator to this high quality 3-row Mishimoto Performance Aluminum Radiator.

    Numbers Talk. Engineered as a superior upgrade to stock performance radiators, the Mishimoto Performance Aluminum Radiator increases coolant capacity by 129 percent (77% over performance pack/GT350 models), coolant surface area (tubes) by 26 percent and air surface area (fins) by 55 percent. That's a whole lot of improvement, so you can keep pushing those RPMs and not worry about overheating. Mishimoto is certain this radiator will keep your engine temperatures down and backs it with their Lifetime Warranty.

    Quality Construction. Designed with a 52mm, 3-row core, this Performance Aluminum Radiator has been TIG-welded to perfection and features a fully brazed aluminum core. The lightweight aluminum construction has been polished to deliver a sharp underhood appearance and it's a direct fit replacement for your stock radiator and comes with a magnetic drain plug.

    Application. The Mishimoto Performance Aluminum Radiator is a direct fit for all 2015-2020 Bullitt, GT, and GT350 including manual and automatic models.

            Best aluminum radiator hands down!

            Why pay about the same for the GT350 radiator when this one is fully aluminum and bigger! For and finish second to none! The black “M” is a nice touch even though you don’t see it once it’s installed and the a/c condenser is mounted in front of it. Fan mounted perfect, as well as the hoses and a/c condenser. The upper and lower mounts are nice and solid being aluminum and not the cheap oem plastic. If you were on the fence about buying this radiator, I shopped around and this turned out to be the best piece out there all around! If you can’t swing the price up front do the Affirm payments and pay it off little by little per month like I did. American muscle stocks some of the best mods out there and shipping and customer service are phenomenal!

            Not the day I was hoping for

            I’d like to give a review on the radiator but after spending several hours taking the front end off and my old radiator out, I found out that I was sent the wrong one. Ya bummer for me. So I got to put everything back together for absolutely nothing. Waste of a half a day.
