Koolance Liquid Coolant Bottle High-Performance 700mL Blue LIQ-702BU-B
Koolance fluorescent blue, high performance, non-toxic liquid coolant. Pre-mixed with corrosion and biological inhibitors. The bottle includes a flexible rubber funnel and small segment of 1/8" ID tubing to make reservoir filling easier.
The total amount is 700mL (23.67 fl oz), which should be a little more than you'll need to fill a typical Koolance system. The recommended replacement period is every 2-3 years, or immediately if there is any change in color or clearness. Freezing point = -15°C.
