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
- Hose
- Clamps
- 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)

So during installation I had a difficult time getting my lower radiator hose (the upgraded Z1 silicon kind) to clear my ac compressor after I installed the lower swirl pot return line adapter. It sure would be nice if there was just the slightest bend in it, or maybe not having the 1/8 npt block not be so large. Other than that it seems to work just fine.
I have been fighting getting the air out my motor ever sense I pulled it and put it back in I have bleed my car numerous ways yet overheat with full mishimoto setup I was lost till a friend told me to get this to get the air out of my car in less then an hour I had super hot heat at idle like you should and no more air no more over heating issues either could literally watch the swirl pot swirl instructions where decent only thing I’d add is what the best spot to cut into the lower rad hose is thanks for a great product
Bought a swirl pot to help with my cooling system, install was straight forward and the hose was easy to route. Works an absolute treat! Was super easy to bleed up (these things are not easy to bleed) whole thing took about 40 mins!
After sales support was A++ as always amd delivery was swift!! Love the work you guys do!!
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!!!!
