    2012 - 2015 Chevy Camaro SS



    The Mishimoto performance aluminum radiator for the 2012–2015 Chevrolet Camaro SS is the ideal upgrade over the stock Camaro radiator. The last thing you want is to be limited by the factory unit during a hot day at the track or when you're stuck in traffic. Our engineers know that, and our design reflects this by increasing cooling efficiency by 22%. Curious how much 22% really is? Well, considering our radiator lets your cooling system gain a 0.25 gallon of extra capacity and lowers coolant temps by a proven 35°F, that 22% is pretty impressive.

    With polished end tanks and all-aluminum construction, the Mishimoto Camaro SS radiator looks as good as it performs. As with all our aluminum radiators, this Camaro SS radiator comes with our signature Lifetime Warranty.

    • Direct fit for 2012-2015 Chevrolet Camaro SS
    • All-aluminum radiator provides a 35°F temperature drop when compared to stock
    • TIG-welded to perfection with a fully brazed aluminum core
    • 0.25 gal of additional fluid capacity
    • Core designed for maximum efficiency over the performance package radiator
    • Fits manual and automatic vehicles
    • Includes Magnetic Drain Plug to capture any metallic debris/fragments in your cooling system
    • Mishimoto Lifetime Warranty

    There are 7 billion people on Earth driving over 1 billion cars. Some of those cars were made for people who spend their Saturdays shopping for houseplants and whose idea of speed is doing 45mph in a 40mph zone. Some of them were made for the passengers of the world, whose perfect car is a silent butler. Then there are the cars made for the select few. For those with fuel in their veins and tire smoke in their lungs. For drivers.

    The fifth-generation Chevy Camaro SS is certainly a driver’s car. With a 6.2L V8 capable of 426 horsepower, independent rear suspension, and launch control, the Camaro is not your average run-around. It’s raced in touring car championships, NASCAR, and even Formula Drift (piloted by none other than Mishimoto-sponsored driver Ryan Tuerck). The SS’s bigger brother, the ZL1, clocked a 7-minute, 41-second Nürburgring lap, keeping pace with Lamborghini, Porsche, and Mercedes. But even Goliath fell to the likes of David.

    The first fifth-generation Camaros to roll off the lot are coming up on seven years old now.  While a person of that age isn’t even fit to reach the pedals, these cars have seen a lot in less than a decade. They’ve likely driven enough miles to circle the earth nearly three times, and their pistons have seen more explosions than Michael Bay’s private screening room. All of this means that certain parts of the car are starting to become a bit weary. Plastic parts are starting to crumble if looked at the wrong way. Piston rings and cylinder walls have developed different political views and aren’t as close as they used to be. The little things are starting to chip away and reveal bigger issues.

    The Camaro SS is an icon of American V8 power.

    But fear not, Mishimoto won’t let your dreams of tearing down an open freeway at the helm of a screaming V8 die quite so soon. We’ve become the loving foster parents of a 2012 Camaro SS and have plans to revive its aching bones with a few upgrades. We’ll start with an aluminum radiator along with an oil cooler to reduce engine temps, and finish up with an oil catch can kit to help clean up its lungs. First, let’s take a look at the design and testing of our Mishimoto aluminum radiator.

    The models that our drafters create are so detailed that they’re often hard to tell from the real thing.
    Design, Build, Test – Repeat

    Like many of our products, the fifth-gen Camaro SS radiator was designed through a combination of manufacturer data and measurements taken from the OEM radiator. From these measurements, our engineers and drafters are able to create an accurate model of the part. That model, along with any specifications, is used to create a prototype radiator. That prototype is what we then use for initial testing.

    Once a prototype is finished, we begin test fitting and performance testing. For our SVP vehicles, that’s a pretty simple task of removing the stock component and installing the prototype. For some projects, like this one, the process is a little more complicated. We often reach out to friends in the industry and our customers to borrow their vehicles for testing. For me, it’s pretty exciting to see the awesome vehicles that our customers drive and put faces to names. Recently, we had the pleasure of working on some powerful MOPAR vehicles in testing our LX chassis radiator. This time we were able to borrow Alexis’s beautiful 2012 Camaro SS.

    For this project, we were able to borrow Alexis’s beautiful 2012 Camaro SS.

    Alexis’s Camaro is certainly a beautiful car and I must say I enjoyed hearing its 6.2L V8 start up on the chilly December mornings. Once the Camaro was settled in our shop, the project engineer, Jason, wasted no time getting the stock radiator out and our shiny new aluminum Mishimoto radiator in.

    “I don’t always engineer radiators; but when I do, they’re excellent.”
    The project engineer, Jason, removing the stock radiator from the Camaro.

    With the old radiator out, Jason was able to seamlessly slip the Mishimoto performance aluminum radiator in its place. While the original radiator looked pretty good for its age, it never hurts to have a little extra insurance with a fully aluminum design and thicker core, especially on such a powerful vehicle. Plus, we’re pretty happy with how the radiator looks in the engine bay.

    The Mishimoto aluminum radiator looks as great as it fits.
    Coming up

    Now that we’ve confirmed fitment, we’ll be taking this SS out for a long highway cruise to test the radiator’s performance. Keep an eye out for the next update with those test results. We’ll also be looking at the development of our fifth-gen Camaro SS oil cooler and catch can kit, so be sure to watch for those threads as well!

    If you grew up working on cars, you’re probably familiar with the clamor that a wrench makes when it hits metal. This sound was once the soundtrack of America, the marching drum of industry. But then came the modern age and that clamor was replaced with the dull thud of plastic. Now, everything is made from plastic. Your computer, your table, your car: plastic. Your Camaro radiator is partly made of plastic, but Mishimoto is changing that.

    At Mishimoto, we see ourselves as modern alchemists, turning plastic into gold…well, aluminum really. It’s no secret that aluminum is far more durable than most plastics. Eventually, that plastic radiator end tank is going to crack or break, leaving you and your Camaro steaming at the side of the road. It’s hard to predict when this will happen, but it is easy to prevent.


    Our last post ended with our production sample installed on our volunteer Camaro. The fit was flawless and the time had come to see if our hard work had paid off. It was finally time for performance testing. With the cooling system bled and a trail of wires connecting engine to computer, the project engineer, Jason, and I jumped in the car and hit the road.

    Turning out of our engineering facility, the Camaro’s thundering exhaust cleared the roads ahead of us. We swept up the I-95 on-ramp and, unleashing 400+ horsepower, Jason began the test. After numerous runs, backs shoved into the bucket seats and the LS3 snarling at traffic as it passed by, we headed back to the shop to analyze the data.


    With all-aluminum end tanks, an almost 5mm thicker core, and 22% greater coolant capacity, we were confident that our radiator would significantly out-perform the stock unit. We were not disappointed. These LS3 and L99 Camaros tend to run hot, putting a lot of stress on the cooling system and their owners. With the stock radiator, we were seeing coolant temps averaging around 180°F at the radiator inlet. Our radiator lowered the inlet temperature by almost 40°F under the same conditions. The result is less stress on the engine, and your heart.


    With our performance testing complete, we’re getting ready to start the pre-sale for this 2012-15 Camaro SS radiator. Make sure to keep an eye on this blog and forum posts for a link to the discounted pre-sale.
