Red Versus Purple Coolant Comparison
UV Appearance
The primary difference between these two bottles is the visual effect under ultraviolet light. The Koolance LIQ-702RD-B contains UV Red fluid. This dye creates a distinct red glow when exposed to UV sources. The Koolance LIQ-702PR-B contains UV Purple fluid. This dye produces a purple glow under the same conditions. Both fluids are designed to highlight the internal components of your cooling loop. You should choose the color that matches your system theme. The chemical performance remains identical regardless of the dye used.
Protection Level
Both products belong to the Koolance 702 series. They share the same core formulation for protecting your hardware. Each bottle includes corrosion inhibitors to guard against metal degradation. They also contain biological inhibitors to prevent bacterial and algae growth. This is critical when dealing with dissimilar metals in your loop. The data confirms both fluids offer high-performance protection. You get the same long-term reliability from either choice. Neither product offers superior chemical protection over the other.
Capacity
Volume is a practical consideration for filling your reservoir. Both the LIQ-702RD-B and LIQ-702PR-B contain 700ml of fluid. This equals 24 fluid ounces per container. The fluid is prediluted, so you can use it directly. This saves time and ensures correct mixture ratios immediately. Both bottles serve as convenient squirt bottles for reservoir filling. You do not need to mix water or additives yourself. The capacity is identical for both models, making this a non-factor.
Maintenance Interval
Longevity and maintenance schedules are consistent across both options. Koolance recommends replacing the coolant every 2 to 3 years. This timeframe applies to both the red and purple variants. You should inspect the fluid regularly for changes in color or clarity. If you notice any shift in appearance, replace it immediately. The shelf life for unused product is 3 years. This ensures you have plenty of time before opening the bottle. Maintenance needs are identical for both products.
Physical Dimensions
Storage and handling depend on the bottle size. Both containers share identical external dimensions. The width is 2.5 inches for each bottle. The height is also 2.5 inches. The length measures 8.5 inches for both models. The LIQ-702RD-B has a listed weight of 0.32 ounces. The weight for the LIQ-702PR-B is not specified in the data. Despite this missing data point, the volume and shape are the same. You will handle both bottles in the same way.
