Product Information

Evans NPG waterless coolant, available in a half-gallon bottle, is recommended for racing engines that run on tracks or in series where propylene glycol-based coolants are allowed but there is a “No Ethylene Glycol” rule. NPG can be used in high performance street vehicles with high flow cooling systems, as well as for food service equipment where ethylene glycol products are contraindicated. NPG is not recommended for daily drivers or cold weather operation, and may require system modifications to ensure a successful conversion.
