When a cylinder head gets hot, coolant can boil right at the surface. Those vapor bubbles stick to the metal and act like insulation creating a hot spot. Fluid can still be moving through the system, but heat is not leaving the head.
NANO-COOL reduces that vapor barrier. It helps the fluid wet the metal instead of sitting on a layer of steam. More coolant contact means better heat transfer from the head and block into the radiator. That can lower engine temperature up to 30 degrees.
It can also be added to any antifreeze, green, yellow, red, orange, glycol, or OAT. Or use it in a water only mix. It does not replace freeze protection. If you need winter coverage, keep the correct antifreeze blend in the system.
