A common issue that affects a cars coolant temps is air. Air is far less efficient at cooling than coolant. Air can also become trapped and create heat pockets throughout a coolant system. Unfortunately, the VQ motors are notorious for having air pockets in the coolant system, even when using a vacuum bleeder.
The GKTECH coolant breather tanks are designed to be a more efficient way to fill and maintain the cooling system, and ensure any air in your system can escape. By connecting common points throughout the coolant system the breather tank allows your system to vent so no air bubbles will get trapped in the system causing coolant to not flow optimally and cause your car to overheat. One of the most crucial aspects to maintaining your engine and your car's general performance, is ensuring your engine can run cool, and the cooling system can operate as intended.
Typically, you would have to piece this kit together yourself. We needed a solution for the various VQ powered vehicles that we own ourselves so we make this kit which includes literally every single piece that you'll need:
- Swirl pot
- Blank radiator cap
- Vehicle specific bracket
- Lower radiator hose junction
- Upper coolant system junction (also doubles as a replacement to the factory plastic unit which is prone to breaking)
Some further info on why a coolant breather tank (aka coolant swirl pot) is such a great idea can be seen here: https://motoiq.com/ask-sarah-motoiq-linked-in/2/

Installed easily using online diagram. I would suggest if using the kit with their hoses to get small bolt/screw hose clamps to make tighter as with theirs was a couple small leaks but may have to do with my higher pressure radiator cap. Also a little bit of teflon tape worked for me on top threaded outlet on swirl pot and on lower radiator hose connector. I had a small problem that was my fualt and John the sales manager helped me out tremendously. Been using for about 2 week now and everything works great. 6/5 stars will definitely use GKTECH in the future.
Extremely impressed with the quality of the kit. Super easy to install and adds another element to protect the coolant system. I have installed this setup on my boosted Z and no longer have to worry about spiking coolant temps. 11/10 Wish I had bought this many moons ago!!!!
Very good quality product and easy to install
Completely fixed my coolant issue ran the car for about eight hours last drift event and did amazing! I was recommended to everybody that had a vq
Extremely impressed with this product and it’s function. First of all install was very easy and able to be done very clean. But at the same time I’m a sucker for that “racecar” look and this is subtle but stands out. Car preformed flawless all day at the track. Coolant temp stayed optimal all day long. No cool down laps needed like before.
