Evans Prep Fluid - Waterless Engine Flush
Most new customers wanting to use Evans will need to remove the existing water based coolant from their system. To Gain the maximum benefit from Evans we recommend that no more than 3% residual water is present in the coolant. To help achieve this we have formulated a hygroscopic Prep Fluid designed to flush the system before adding Evans.
How Does It Work?
Fill the freshly drained cooling system with Evans Prep Fluid and run the engine up to normal operating temperature. The hygroscopic fluid will absorb any residual water and flush out any loose deposits.
What should I do with it then?
Once the Prep Fluid has been drained from the system, store it in an air tight container as it can be used several times.
Available in 2litre or 5 litre (Please call if you require 25 Litres)
About Evans Waterless Coolant
Since the 1930's engine coolants have been based on a mixture of water, ethylene glycol (antifreeze) and corrosion inhibitors. These mixtures have inherent physical and chemical limitations, they affect engine performance and in some circumstances lead to engine failures.
According to the British Testing Council - Testing Advisory Group... " up to 60% of engine failures can be attributed to cooling system failures"... confirming there are inherent flaws associated to water-based coolants and emphasising the need for something better!
EVANS WATERLESS COOLANT - Waterless coolant represents a major step forward in engine cooling technology which, over the last 20 years, have proven to increase engine reliability, reduce maintenance costs and improve performance.
NO WATER - NO OVERHEATING
Evans Waterless Coolants have boiling points above 180°C, effectively eliminating overheating, boil-over and after-boil.
NO WATER - NO PRESSURE
Evans Waterless Coolants have a very low vapour pressure, eradicating the danger of scalding and reducing the strain on engine components.
NO WATER - NO CORROSION
Water contains oxygen and acts as an electrolyte which leads to corrosion. Evans Waterless Coolants eliminate these corrosion sources.
NO WATER - MORE BHP
Evans waterless Coolants eliminate engine hotspots which lead to poor combustion and loss of power.
NO WATER - NO LINER EROSION
Evans Waterless Coolants are proven to reduce liner pitting by 75% compared with water based coolants.
NO WATER - NO SCALING
Water contains impurities and hardness salts that lead to scaling and poor heat transfer. Evans Waterless Coolants contain none of these impurities.
NON TOXIC
Evans Waterless Coolants are proven to be Non-Toxic. Standard anti-freeze is toxic and known to kill pets.
