The ModWater coolant lineup has grown with four new UV-reactive colors, joining the existing catalog of clear, red, and blue formulas. All ModWater coolants share the same non-toxic, corrosion-resistant base, so you can pick purely on aesthetics without worrying about performance differences between colors.

As always, avoid mixing coolant with metals it is not rated for, and double check your loop's block and radiator materials against the compatibility notes on each product page. Mixed metal loops should use the neutral formula unless a specific mixed-metal coolant is called out.

Bottles are available in 1-liter sizes, and a mixed-metal-safe version is available on request through customer support for anyone running an unusual combination of materials.
