![]() ![]() I'm not looking to run my engine a LOT hotter - especially the engine on the 51 year old TR3. This is why we normally don't run 100% antifreeze in our systems, and probably one of the reasons my old TR was originally instructed to run with "clean rain water" unless it was frosty. Densities are less than 5% different, so on a volumetric basis water can carry over 60% greater heat. Propylene glycol is about 2.5, ethylene glycol about 2.4. The heat capacity of water is about 4.2 J/cubic cm-K-degree. So much higher boiling for the waterless. The 0 psi boiling point of propylene glycol is 375 F (190 C). That's a thermodynamic fact.įrom info on the interwebs about the Evans waterless coolant it seems to be a blend of ethylene glycol and propylene glycol (that's speculative in part). They do a poorer job of carrying heat away from the cylinders. Standard anti-freeze is toxic and known to kill pets.We've talked about this a lot on the vintage Triumphs list and the TR Register forum.Īn important thing to remember is that although these ethylene and/or propylene glycol-based coolants have significantly higher boiling point than water or water-glycol blends, it comes at a price of lower heat capacity in the fluid. Evans Waterless Coolants contain none of these impurities.Įvans Waterless Coolants are proven to be Non-Toxic. Water contains impurities and hardness salts that lead to scaling and poor heat transfer. Evans Waterless Coolants eliminate these corrosion sources.Įvans waterless Coolants eliminate engine hotspots which lead to poor combustion and loss of power.Įvans Waterless Coolants are proven to reduce liner pitting by 75% compared with water based coolants. Water contains oxygen and acts as an electrolyte which leads to corrosion. confirming there are inherent flaws associated to water-based coolants and emphasising the need for something better!ĮVANS 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.Įvans Waterless Coolants have boiling points above 180☌, effectively eliminating overheating, boil-over and after-boil.Įvans Waterless Coolants have a very low vapour pressure, eradicating the danger of scalding and reducing the strain on engine components. "up to 60% of engine failures can be attributed to cooling system failures". These mixtures have inherent physical and chemical limitations, they affect engine performance and in some circumstances lead to engine failures.Īccording to the British Testing Council - Testing Advisory Group. Since the 1930's engine coolants have been based on a mixture of water, ethylene glycol (antifreeze) and corrosion inhibitors. Please Note: If switching to Evans Waterless Coolant for the first time you must also purchase EVANS Hygroscopic Prep Fluid to remove any dirt, scale and residual coolant.Īvailable in 2 litres or 5 litres (Please call if you require 25Litres). This enables tuners to squeeze the maximum BHP from their engines. Power Cool 180☌ has a much higher boiling point than water or water-based coolants and ensures the heat-energy is always being removed, no matter what the load. Efficient heat dissipation is often compromised because water-based coolants boil inside the block, sometimes leading to catastrophic engine failure. ![]() This means delivering the greatest amount of fuel possible, without overheating the engine. ![]() To be competitive racing teams have to push their engines to the limit. Optimised for performance car engines primarily fabricated from aluminium plus some steel and copper components. ![]()
