Description

Stainless Steel reservoir/fill tank for setting up your air to water cooling system for best performance and eliminate air in the system automatically.

A beautifully polished unit that will outlast the life of your car. The use of this product allows you to run your personalized coolant mix for your setup.   You can run distilled water with some water wetter or a small amount of coolant for pump lubrication.   Water has better heat capacity and transfer than coolant. The unit allows for full-time air bleeding of the system as the air passes through the heat exchanger it is pushed out into the reservoir. this keeps your water in pristine air-free condition for the best cooling.   Air bubbles in the system will reduce performance dramatically.

The unit comes with a bracket that mounts to your car frame for ease of installation.
