Never Over Heat Again! Evans Waterless Technology coolants are chemical blends that yield more efficient engine cooling compared to conventional coolants. Lack of coolant vaporization results in better metal temperature control and the increased boiling point (375¡ at zero psi.) eliminates boil-over, cavitation and detonation. WhatÕs more, cooling system electrolysis and corrosion (critical issues with Jaguar engines) are eliminated. While not inexpensive, these are lifetime products that never need to be replaced; given all the benefits, they represent an excellent value. Evans Waterless High Performance Coolant Suitable for all gasoline and light-duty diesel engines and is safe for stored vehicles and those operated in extreme cold. It meets modified ASTM D 1384 corrosion testing. Note that the entire cooling system must be drained and refilled with 100 percent Evans Waterless Coolant. NO WATER. Sold per gallon.

We also offer a conversion kit designed for DIY installations.
