How each alternative compares
Koolance 702 UV Yellow Coolant 700ml
The Koolance 702 UV Yellow Coolant matches the original in volume and physical dimensions. You get the same 24 fl oz capacity and 700ml size in a compact 2.5 by 2.5 by 8.5 inch bottle.

The Koolance 702 UV Purple Coolant offers the same core benefits as the red version. It provides 24 fl oz of prediluted fluid in the same 700ml bottle format.

Koolance 702 UV Red Coolant 5L
The Koolance 702 UV Red Coolant 5L provides a significantly larger supply of the same fluid. You get 5 liters instead of 700ml. The bottle is much larger, measuring 10 by 12.3 by 6.5 inches and weighing 13 pounds. This bulk option eliminates the need to mix concentrate. You receive the same UV Red color and inhibitor protection. It is best for large custom loops that require substantial fluid volume. You avoid multiple smaller bottles.
