Kept my water pump in my pc running since 2008. Just recently replaced the pump due to concern it's gonna give out sometime, but to have a pump run 16 years, pretty good stuff. Also does a great job cooling my pc. Review: EXTREMELY LONG LONGEVITY!!! - Updated review: I am going on 4 years now with this coolant in my custom loop. It looks and works amazing still!!!! There is nothing in the lines visibly, no gunk, and ive only had to top it off once or twice with very little fluid. ## Features - Koolance 702 series coolant is used by many industries requiring a high performance, low-toxicity, reliable coolant with corrosion and biological inhibitors. - A high quality coolant is extremely important for addressing dissimilar metals and biologic growth (bacterial and algae) long-term. - Koolance liquids will not clog components and can typically be used for 2-3 years before replacement is recommended. - (Coolant shelf life is 3 years.)

And would you recommend this coolant?** A: We're the manufacturer. With our products (tubing, cold plates, radiators, reservoirs) and no other coolant additives, we've not seen those types of issues with our blue LIQ-702BU-B coolant. We can't speak for products of other brands because we don't test them. **Q: Can you add distilled water to fill up a loop if one bottle is not enough?** A: You could. You could run the whole loop on distilled water alone. But mixing it with the coolant will dilute whatever anticorrosion and anti microbial benefits the additives grant, and possibly lighten the color if it's a lot of added water. Other than that, I don't think there's any major negatives. **Q: is it alright to mix metals with this** A: You might want to clarify your question. If you mean to mix metals as some kind of additive or coloring, I have no idea. If you mean use a copper water block and a steel radiator, then yes. My setup uses a copper water block, a steel radiator, and metal connectors (which I believe are also steel). I've had no problems other than a minor leak of the tubing at the connectors and this is my second container of coolant in almost a decade. My system is a water cooled Xbox 360. **Q: Can this be diluted with water to make it more clear ( i plan to use this with a alpha cool helex and from the photos i see it becomes very opaqe?** A: Water can't be added, because it negatively affects the corrosion and biological protection. Instead, it can be mixed with clear LIQ-702CL-B coolant to maintain the proper additive ratios. (Do not mix with LIQ-705, which is a different coolant.) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great stuff!!! *by S***X on November 11, 2024* Been using this brand for years.
