S10 EASA AD Coolant Specification

May 29, 2007 | 2007-0155

Under certain powerplant installation and operating conditions, boiling of conventional coolant with a mixing ratio of 50% coolant and 50% water can occur before reaching maximum permissible cylinder head temperatures (CHT). This can lead to evaporation of the coolant and in consequences to loss of coolant in the coolant system, causing the engine to overheat. This condition, if not corrected could result in engine damage or an accident.
