Waterless Engine Coolants for your Classic, Vintage or Performance Car

Evans waterless coolants

We are able to convert your Classic, Vintage or Performance vehicle's water based coolant system to a waterless one using a unique range of non-toxic waterless coolants specifically produced for internal combustion engines. Evans coolants are proven to overcome the problems and limitations associated with water-based coolants.

No Water - No Corrosion - No Pressure - No Problems!

Water is the root cause of corrosion in engines. Current antifreeze formulations regularly fail to prevent cavitation, oxidation and galvanic action, eating away pumps, radiators, liners etc. Corrosion build-up, inhibitor drop-out and lime-scale precipitation significantly reduces heat transfer efficiency and accelerates overheating. Evans Waterless Coolants eliminate all causes of cooling system corrosion.

Evans waterless coolantsHotspots within the engine cooling system cause localised boiling. The steam generated significantly increases the pressure within the system putting stress on hoses and other components. As water flows through an engine cooling system it is subjected to many obstacles and constrictions. Evans Waterless Coolants have a boiling point of above 180°C and will not vaporise within the cooling system, as a result cooling system pressure is greatly reduced.

Evans Waterless Coolants have a much higher vapour pressure than water which means it is far less likely to vaporise when subjected to the turbulent pressure changes. Tests performed by the Southwest Research Institute conducted on behalf of John Deere concluded that Evans Waterless Coolants achieved results that can not be matched by any water based coolant. The 250 hour engine dynamometer test, approved by ASTM international, quantified the amount of cylinder liner pitting caused by cavitation errosion. Many coolants were tested during the trial period and results confirmed that up to 75% less pitting occured when using waterless engine coolants.

  • Evans has been proven to last more than 20 years and could reasonably be considered as ‘The coolant for engine life’
  • Evans does not oxidise inside an engine or support galvanic activity, effectively eliminating all corrosion – permanently!
  • Evans has natural antifreeze properties freezing below -40ºC, does not degrade inside a cooling system and is Non-Toxic. Thus eliminating the worry about topping-up or recharging with antifreeze every winter
  • Evans coolants have a much lower vapour pressure compared with water-based coolants

What's wrong with water coolant?

First used in engines some 100 years ago, water-based coolants are universally acknowledged to have inherent physical and chemical limitations that effect long-term reliability, increase maintenance costs and often restrict engine performance.

Statistics published by manufacturers and motoring organisations confirm, that water is the root cause for 60% of engine breakdowns and 40% of catastrophic failures.

Whilst internal damage goes mostly unnoticed in new engines, the cumulative effects of corrosion, cavitation and cyclic pressurisation become increasingly apparent over time.

For decades engine designers and antifreeze formulators have persisted with water whilst endeavouring to overcome its intrinsic shortcomings - primarily because there has been no viable alternative.

The waterless coolant solution...

Jack Evans, a cooling system designer, also struggled for many years with waters limitations and was determined to find a better solution.

Finally, in 1993, Jack formulated a synthetic coolant which eliminated corrosion, erosion, overheating, significantly reduced system pressure and maintained heat transfer equilibrium.

Over the last twenty years Evans waterless engine coolants have been tested and proven by OEM’s, fleet operators, racing teams, professional restorers, plant operators and automotive aficionados to increase reliability and reduce operating costs.

The high boiling point of Evans coolants are also facilitating improvements in engine design, performance and fuel economy.
