Mishimoto 5th Gen SS Aluminum Radiator R&D

Hey everybody!

My name is Steve and I'm an automotive journalist with Mishimoto Automotive. You may have seen posts by my coworker, Gardiner, on the Camaro 6 forums that talk about our R&D process for our 6th Gen SS parts. Well, I'm here to do the same thing and show the 5th Gen Camaro SS some much deserved love. We're in the process of creating a few new products for the 5th Gen Camaro SS starting off with a performance aluminum radiator. Check out the first part of our R&D process below! Feel free to let me know if you have any comments or questions; we always look forward to your feedback!

Cooling The American Dream – Radiator R&D, Part 1: Design And Test-Fit



A Car for Drivers

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.


Our prototype 5th-gen Camaro SS radiator

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!

Thanks for reading!

-Steve

I understand there's a difference between 10-12 and 13-15 models. I have a 14', would this radiator fit in my car?

I would like to see one that is made for the 2014-2015 ss 1le or the zl1, because I would really buy one of your radiators, however; I do not see the fan shroud bottom tabs the same as the fan shroud tabs for the 14-15 models to work as there is 3 tabs at the bottom of the fan shroud. Also the other issue I see is the oil cooler connection located on bottom drivers side to connect to. Please let me know if you guys ever make one.

Is the fill neck in the same location as the 2010-2011 vehicles? Checking to see if this will still work with the OTR intakes out there

Yes a very interesting modification that could be a real good seller as the plastic/aluminum stock one is doomed to fail .

Hey everybody,

Thanks for the feedback! Hopefully I can answer some of your questions.

It looks like the fill neck design and a few other changes were made between the 2011 and 2012 radiator. This radiator will fit with any 2012-15 SS, so you should be good with a 2014!

This radiator should fit with FI piping. The height and width remain unchanged from the stock radiator. It is important to note, however, that the core thickness has been increased by about 13mm.

The fill neck on the 2010-11 radiators is slightly offset to the right of center (when looking at the front of the radiator), while the 2012-15 is offset to the left. Depending on which OTR intake you're looking at, this may not be an issue. We also offer a performance radiator specifically for the 2010-11 SS if that's what you're looking for: http://mishimo.to/2j0RkHX

I hope that answers your questions! Keep the feedback coming!

Thanks!

-Steve

Thanks for the feedback! I will pass this on to our product development team; if mount additions are all that's necessary we may be able to update this model to fit. I'll definitely keep you in the loop!

I'll take a pic for you of what is needed for 2014-2015 SS 1LE and the zL1. I would buy one if this gets done. Stand by for pics when I get home....

I installed one of these last summer and the bottom rectangular brackets measurements were quite a bit off. I had to take a dremel to the nipples that fit in them to make it work.

I also had a hell of a time getting it to bleed. I've replaced 5 or 6 radiators in my time and I've never had a problem getting this done until the Mishimoto unit. I initially filled it up as far as it would go, then turned the car on with the cap off while I waited for it to warm up. Next thing I know the radiator is spraying coolant all over the place, a behavior I'd never before seen. Usually the radiators fluid level would drop as the car ran in the others I'd worked on, with the coolant filling up the system. Not sure if it was an errant air pocket or what but it did this 5 or 6 times before I said whatever and topped it off and closed it.

Overall good build quality with nice welds all over. It was packed well for shipment too.

That would be great! I ran this by the engineer for the project and it looks like the render and production sample that I have pictured are a version behind. There are 3 fan-shroud mounts on the final design, just need to check on the oil cooler connection you mentioned. I'm working on getting updated renders for you guys.

We should be good for now with Jayjellyfish212's photos but I will definitely keep you in mind and let the project manager know you're around! What color is your 1LE? I've probably oogled it before, haha.

Thanks!

Hey fastbroshi!

Sorry to hear you had difficulty installing and bleeding our 2010-11 SS radiator. Did you by any chance contact customer service about this? I'll be sure to pass this up to them and make sure it's not a recurring issue that we need to address with that product.

We've found with a few vehicles that the upper hose for the radiator sits almost level with the highest point on the motor, which can make it tough to bleed if the rad isn't quite seated or the car isn't on level ground. This rad and the 2010-11 version aren't any taller than their stock counterparts so that shouldn't be an issue.

I appreciate the feedback and apologize again for trouble you had installing the radiator. Definitely let me know if there's anything more I can do to help!

Thanks!

-Steve
