Engine overheating is a major cause of vehicle breakdown, often resulting in permanent damage.
In 2013 the AA responded to more than 56,000 breakdowns caused by engine overheating
The most common reason for engine overheating is coolant boil-over, when the boiling-point of the liquid coolant is exceeded and it turns to steam (vaporises).
Water-based engine coolants are prone to boil and vaporise when;
*Overheating caused by restrictions to air and coolant flow increase with vehicle age and mileage.
Evans coolants have a boiling point greater than 180°C, compared with 104°C for 50-50 water-based coolants. Evans high boiling point guarantees the waterless coolant remains in liquid form and does not vaporise - thus eliminating overheating.
Evans cooled engines always achieve thermal equilibrium (heat balance) with the ambient air and run perfectly well at temperatures between 105 - 115°C.
