How to Choose Mayhems Parts
-
Check Volume Needs
Match your loop capacity to the fluid size. Small builds fit the 250 ml concentrates or the 15 ml dye. Large loops require the 5 Litre premixed options. The XT1 250 ml Coolant Concentrate offers corrosion protection in a compact bottle. You dilute it yourself for precise control. If you have a large system, the 5 Litre premixed fluids save time. They eliminate manual mixing. Choose the size that matches your total loop volume to avoid waste.
-
Decide on Mixing
Choose between concentrates and premixed fluids. Concentrates like the XT1 250 ml Coolant Concentrate require you to mix the fluid with pure water. This gives you full control over the final mixture. Premixed options like the XT1 Premixed PC Coolant 1 Litre are ready to pour. They simplify the process by removing the need for measuring. If you prefer a straightforward fill, pick a premixed option. If you want custom dilution ratios, select a concentrate.
-
Select Color Formula
Pick a color that suits your aesthetic and maintenance preferences. The XT1 line offers Tree Viper Green with strong corrosion protection. The X1 Neon Sunset Orange Concentrate uses a biodegradable vegetable-extract formula. This provides a unique orange hue while being environmentally friendly. You can also use the 15 ml Tree Viper Green Coolant Dye to tint existing clear fluids. Decide if you want a pre-dyed green or a custom orange shade.
-
Verify Base Fluid
If you use concentrates, you need a pure base. The Mayhems Ultra Pure H2O 5 Litre Liquid provides reverse-osmosis filtered water. It has less than 1 microsiemens of electrical conductivity. This low conductivity prevents short circuits and corrosion. You mix this water with your chosen concentrate. Do not use tap water. The Ultra Pure H2O is designed specifically for diluting Mayhems concentrates. Ensure you have this base fluid if you choose a concentrate route.
-
Plan for Maintenance
Include cleaning supplies in your parts list. The Mayhems Blitz Part 2 System Cleaning Kit helps flush your loop during maintenance. It includes the 125 ml Blitz Part 2 solution and testing accessories. This kit is essential for complete loop flushing. You should keep it on hand for regular upkeep.
