OPERATION 14. COLD WEATHER OPERATION 14.1 PRECAUTIONS FOR LOW TEMPERATURE Extremely low temperatures may make the engine difficult to start, and cause the coolant to freeze, so do as follows. 14.1.1 FUEL AND LUBRICANTS Use fuel and oil with low viscosity for all components. For details, see "20. USE OF FUEL, COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE on page 3-11. 14.1.2 COOLANT WARNING Keep antifreeze fluid away from open flame. Never smoke when using antifreeze. NOTE: Never use methanol-, ethanol- or propanol-based antifreeze.
Absolutely avoid using any water-leak-preventing agent either independently or mixed with an antifreeze Do not mix one antifreeze brand with a different brand. For details of the antifreeze mixture requirements, see "20.3 COOLANT SPECIFICATIONS" on page 3-14. 14.1.3 BATTERY WARNING Keep batteries away from sparks and open flame. Battery electrolyte is acidic and will cause injury if allowed to contact skin or eyes. If it contacts skin or eyes, immediately flush it away with large amounts of water and consult medical help. Battery capacity drops as the ambient temperature falls. And if the battery charge is low enough, the electrolyte may freeze.
Maintain the charge as high as possible and protect batteries from cold. 2-76 WA320-3MC Rate of charge Temperature of fluid 20 (68 0 (32 -10 (14 -20 (-4 -30 (-22 F) 100% 1.28 1.29 1.31 1.31 1.32 90% 1.26 1.27 1.28 1.29 1.30 80% 1.24 1.25 1.26 1.27 1.28 75% 1.23 1.24 1.25 1.26 1.27
