Our top pick: Koolance 702 UV Yellow Coolant 700ml.
How each alternative compares
Koolance 702 UV Red Coolant (700ml)
This Koolance 702 UV Red Coolant shares the same 700ml volume and prediluted convenience as the original. It uses the same LIQ-702 series formulation, offering identical corrosion and biological inhibitors for dissimilar metals. The primary difference is the UV Red color, which replaces the original UV Yellow. You get the same 24 fl oz capacity in a bottle with identical dimensions of 8.5 by 2.5 by 2.5 inches. Choose this if you want the same reliable protection and easy squirt-bottle filling but prefer a red aesthetic for your loop. It gives up the yellow glow but keeps all performance specs.
Koolance 702 UV Purple Coolant (700ml)
The Koolance 702 UV Purple Coolant matches the original in volume and convenience. It provides the same 700ml of prediluted fluid with corrosion and biological inhibitors. The main distinction is the UV Purple color instead of UV Yellow. Like the original, it comes in a 24 fl oz container designed for easy reservoir filling. The bottle dimensions remain 8.5 by 2.5 by 2.5 inches. Select this option if you need the same high-performance protection and ease of use but want a purple visual theme. It sacrifices the yellow hue while maintaining identical chemical protection and physical form factor.
XSPC Pure Premix UV Yellow 1L
This XSPC Pure Premix offers a larger 1L volume compared to the original 700ml. It provides UV Yellow color, matching the original aesthetic. As a premix, it delivers mixed-metal protection similar to the Koolance inhibitors. The bottle is slightly shorter at 8.07 inches but wider at 2.56 inches. You gain more fluid for filling larger loops but lose the specific Koolance brand formulation. This option suits builders who need extra volume and standard yellow UV visibility without the smaller 700ml constraint. It gives up the exact Koolance chemical profile for broader metal compatibility in a larger container.
XSPC Pure Premix UV Yellow Coolant 2-Pack
This XSPC 2-Pack provides two 1L bottles of UV Yellow premix coolant. You get double the volume of the original 700ml bottle, totaling 2L of fluid. The color matches the original UV Yellow. It offers mixed-metal protection and low conductivity, functioning similarly to the original inhibitors. The packaging differs, providing two separate units rather than a single squirt bottle. This choice benefits builders needing significant volume for large loops or future expansions. It sacrifices the single convenient filling bottle for greater total fluid quantity and the ability to fill multiple systems or larger capacities.
XSPC Pure Premix UV Yellow 1000mL with Filling Kit
This XSPC Pure Premix includes 1000ml of UV Yellow fluid, exceeding the original 700ml volume. It comes with a filling kit, including a cap and straw, which differs from the original squirt bottle design. The coolant offers aluminum-safe protection, aligning with the original corrosion inhibitor goals. The bottle lacks the original's specific dimensions, focusing instead on the included tooling. Select this if you need more fluid and a dedicated filling tool for precision. It gives up the simple squeeze-bottle convenience for a more structured filling process and greater total volume in a single purchase.
