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)
