Evans High Performance Waterless Coolant

Evans High Performance Waterless Coolant


Evans waterless coolants offer several benefits to save you money, time and engine wear.

  • No Corrosion:  By removing water from the cooling components, Evans eliminates water-caused corrosion in the cooling system.
  • No Pressure:  Evans coolants will always remain in liquid form, preventing stress on cooling system components such as hoses, pump seals and radiator seams due to high vapor pressure.
  • No Overheating:  With a boiling point of 375ºF compared to only 226ºF for water-based antifreeze, Evans Waterless Coolants expand the range of safe operating temperatures in you vehicle while eliminating the risk of boil over.
  • No Erosion:  Even under extreme conditions, Evans coolants remain in liquid form and do not vaporize, preventing the pitting caused by water vapor.
  • No Electrolysis:  The absence of water, substantially reduces electrical conductivity of Evans coolants which sharply reduces incidents of electrolysis.
  • Freeze Protection:  Evans coolants have natural antifreeze properties down to -40°F and will not solidify or expand, providing protection from freeze bursts.
  • Extended Lifecycle:  Evans coolants do not degrade and are designed to provide an extended service, in many cases resulting in a lifetime fill.


Evans High Performance waterless coolant is designed to eliminate many problems associated with water in conventional water-based cooling systems, while increasing reliability and engine life.

Evans High Performance coolant is ready to use—no water required. It contains no silicates or phosphates and requires no Supplemental Coolant Additive (SCA).

  • Boiling Point: Above 190°C
  • Antifreeze Properties: Protects below -40°C
  • Benefits: Eliminates corrosion and pump cavitation, reduces system pressure, prevents overheating, maximizes BHP
  • Life Span: Extended life

This is the ONLY coolant permissible to use in any Viking Aircraft Engines.  Unfortunately Evans do not appear to have an Australian distributor at the moment, so Swish Projects purchases Evans Coolant by the pallet load and it’s here for you when you need it.  All other engine consumables are readily available from any reputable auto parts retailer (gear box oil, engine oil and filters etc).

Price INCLUDES freight of a single 1 US GAL (3.8L) bottle to you.  All new engine sales from April 2023 will have two bottles included as part of their standard firewall forward order.
