They say that good things come to those who wait, and we'd certainly say that's the case with the Mishimoto 2016+ Camaro expansion tank. Note that I did not specify "SS" here. This tank also fits on the 2.0T, but we haven't gotten a change to test it out on a V6 model yet, though it should fit. If any V6 owners are local to the Philadelphia area and want to come on by for a test fit so that we can be 100% sure, please reach out!

We've tested the tank on both of our Camaros, and we've gone through several stages of refinement, ultimately ending up with quite the fine-looking aluminum piece. Oh, and did I mention it's already on Pre-Sale?

Let's take a gander at how the final product came out!

Expanding on the Stock Design

As a reminder for those of you who have been following along the whole time, and as a quick catch-me-up for those of you who are just joining us, the stock tank design in this car actually comprises two different

I have been a big fan of Subaru vehicles for a substantial part of my life, and I have lots of experience with WRXs, but the BRZ (and FR-S) is still very new to me. Not too long ago, one of our engineers had his 2013 Subaru BRZ out in the parking lot, and I asked him to pop the hood so that I might check out the power plant. Have you ever seen an old episode of Scooby-Doo when Shaggy opens a door and jumps about a mile in the air, screaming, having revealed the spooky ghost residing therein? Well, you can call me Shaggy, and here is the ghost:

Like, zoinks! Look at all that hideous white plastic - nobody wants a haunted Toyobaru, but how on earth would one solve this problem? Who ya gonna call?

Overflow Tank Functionality

Our ghostbusters engineers are already chugging right along in the development of an awesome new overflow tank for the 2013+ FR-S/BRZ. An overflow tank is an important part of a car's cooling system; it serves to receive and store

Design work and refinement continue with our 2016 Camaro expansion tank. To verify fitment within the constraints of the engine bay, we've 3D printed a prototype in plastic to install on our test vehicle.

Check out a few shots of this prototype installed!

The image above shows the tank with a sight tube instead of a sight glass, which we used on our previous 3D models. We are experimenting with both designs to determine which is easier to read and which is going to provide the most durability. Let us know what you think!

Along with the mounting points, we also need to ensure that all the hose connection points are in the same location as the stock tank.

A few minor adjustments are needed on the design, but this first prototype fit quite well.

Coming Up - Functional Prototype

Now that we've made design adjustments, we can begin constructing our first

While we were deep in development of various new components for the 2016 Camaro, we received numerous requests for a replacement for the coolant expansion tank. While an upgrade here won't net any horsepower gains or drop fluid temperatures, a replacement tank can certainly improve the appearance of your engine bay.

Since we are experts in producing innovative aluminum replacement expansion tanks, we decided to tackle the Camaro unit as one of our new projects.

Stock 2016 Camaro Expansion Tank

The stock 2016 Camaro expansion tank is quite a unique piece. GM has combined the expansion tank and overflow tank into one unit. If you've ever peeked under the hood of a Cadillac ATS, this unit should look familiar.

Before designing our own aluminum counterpart, we needed to inspect the stock 2016 Camaro parts and evaluate each of the features.

We last left you with some details of our initial design and a hint of an upcoming pre-sale for this overflow tank. Unfortunately, since that initial test fit we hit a few snags in the design process. Our goal with this product is to provide compatible fitment with all our other 2008+ WRX and STi components. This required numerous stages of test fitting, one of which revealed an issue. With our larger 3-row X-Line aluminum radiator installed, our sight tube on this expansion tank design ended up too close to the belt drive system on our Subaru.

We decided a revision was necessary. Although the two components were not physically touching, the clearances were just too tight for our comfort. Luckily, our team had an alternate means of measuring fluid within the tank. This comes in the form of a dipstick!

If you haven't noticed, the folks here at Mishimoto are not fans of plastic use for cooling system components. A large number of our products provide a more durable material, aluminum, to replace the failure-prone plastic parts, and now we are focusing on another line of products, our aluminum coolant expansion tanks. We offer two different options for the WRX/STI and one for the new Mustang EcoBoost. This article is focused around our newest addition, an aluminum overflow tank for the 2008+ WRX and STI.

Product Design

We won't be making any significant changes to the design of this tank compared to the stock unit, except for the construction material. Enlarging the tank's capacity will have no impact on fluid temperatures or cooling efficiency, so this will not be necessary.

We snagged a stock overflow tank and started gathering
