WaterTotal coolants HD platinum premix is up to 25-40% more effective at Transferring heat than conventional Glycol Based antifreeze coolants. | EG (50%)Ethylene Glycol is around 20 times more viscous than water and therefore this viscosity will affect how freely the coolant can flow through the cooling passage. | EG (100%)The lower the viscosity of Total Coolants Platinum Coolant will increase the cooling efficiency of the system. |
