TANKS, BUT NO TANKS – OVERFLOW TANK, PART 1: OEM REVIEW AND 3D MODELS
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?
Mishimoto!
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 coolant that is purged from the radiator in high-pressure situations. An overflow tank, unlike an expansion tank, is not pressurized and contains a vacuum line through which coolant is drawn back into the system when needed. An expansion tank is part of a sealed, pressurized system that allows the radiator to purge coolant when it is overly hot and expansive, and to draw it back in when the system cools to a sufficient degree. It does this by utilizing the pressure differential that varies with temperature to create a vacuum condition due to air that is part of the system; another important distinction is that coolant does not have to purge through a pressure cap before entering the tank because it is a pressurized component in the system.
As you can see, the OEM unit is a bulbous hunk of white plastic (although this one is sporting a snazzy Mishimoto silicone coolant line – part of our BRZ/FR-S Radiator Hose Kit). Our Mishimoto tank replacement will be an attractive aluminum piece, and it will hold a larger volume of coolant than the OEM unit. We have already modeled the piece and recently 3D printed it to check fitment.
In order to test fit, we needed first to remove that OEM poltergeist.
After the exorcism was complete, we made quick work of throwing in our prototype.
The tank fit well and looks markedly better than the OEM unit! Check out a photo of the two pieces side by side for a more direct comparison.
Definitely an improvement, and it will look even better in aluminum!
OVERFLOWING WITH STYLE – OVERFLOW TANK, PART 2: PRE-SALE
Hello everyone, and welcome to the long-awaited second chapter in the saga of the Mishimoto BRZ expansion tank! I know it’s been a little while since our first update, and you all have waited patiently, so I am excited to share some good news about these BRZ parts (or FR-S parts).
You might remember from my last update that the stock, ghostly-looking overflow tank that haunts the engine bay of your BRZ, GT86, or FR-S really spooked us. So much so, in fact, that we felt obligated to provide you with an alternative – a way to absolve the BRZ of negative energy and transform your engine bay into something inspiring, rather than terrifying.
Though Halloween may be approaching and ghosts or monsters seem to be appearing everywhere (even around our office), we at Mishimoto don’t think that anything so scary looking should ever be in your engine bay. That’s why we’ve decided to begin the pre-sale for the Mishimoto BRZ expansion tank today, during the week leading up to the spookiest day of the year.
Rendering our Replacement BRZ Parts
We went through several iterations of this design to ensure that it fits your car perfectly, which is why it has been a little while since our last update. We had some adjustments to make along the way, but once we were crystal clear on all of our final dimensions, our drafting team mocked up the final product in their rendering suite.
Pretty darn nice, right? The tank bolts tightly up to the stock location on the side of the fan shroud, and it will work with the stock fan shroud or the Mishimoto BRZ fan shroud.
It’s ALIVE!!!!
Renders are well and good, but the final product is what really counts. Our engineers knew they could work their magic to rid the BRZ and FR-S of this plastic demon, and I am happy to share with you the fruits of their labor: a heavenly-looking, all-aluminum example of aesthetic enlightenment, designed to exorcise your BRZ of the stock plastic tank that struck fear and disgust into even the bravest of souls.
Here it is in its polished aluminum finish.
And for those of you who are going for a darker, subtler, perhaps, more sinister vibe, we are offering the tank in black as well.
