OPERATION 14. COLD WEATHER OPERATIONS 14.1 PRECAUTIONS FOR LOW TEMPERATURE If the temperature drops real low, it may becomes difficult to start the engine, and the coolant may freeze, so do as follows. 14.1.1 FUEL AND LUBRICANTS Change to fuel and oil with low viscosity for all components. For details of the specified viscosity, see "20. USE OF FUEL, COOLANT AND LUBRI- CANTS ACCORDING TO AMBIENT TEMPERATURE. on page 3-10. 14.1.2 COOLANT WARNING Keep antifreeze fluid away from an open flame. Never smoke when using antifreeze. NOTICE: ! Never use methanol, ethanol or propanol based antifreeze. !
Absolutely avoid using any water leak preventing agent irrespective of whether it is used independently or mixed with an antifreeze ! Do not mix one antifreeze with a different brand. For details of the antifreeze mixture requirements, see "20.3 COOLANT SPECIFICATIONS" on page 3-13. 2-63
