OPERATION
350
For cold weather operation, follow these recommendations:
앫 When starting the engine in temperatures below –15°C (5°F), use
engine lubricants of lower viscosity. See the Operator's Manual
Vehicle Maintenance for additional information.
앫 When the temperature is below freezing, make sure the
concentration of antifreeze in the coolant is sufficient to prevent
freezing. Refer to the Operator's Manual Vehicle Maintenance for
additional information.
앫 During cold weather, pay more attention to the condition of the
batteries. Test them frequently to ensure sufficient power for
starting. A dead battery may freeze.
앫 Fuel cloud point is the temperature at which wax crystals become
visible, which is generally above the pour point of the fuel. To
keep the fuel filter elements from plugging with wax crystals, the
cloud point should be no higher than the lowest ambient
temperature at which the engine must start.
To prevent wear and possible damage to the engine when it is cold,
gradually bring it up to operating temperature before operating at high
engine speeds or full load. After starting and before moving the vehicle,
run the engine at 800 to 1000 rpm for 3 to 5 minutes. Operate at partial
engine load until the coolant temperature reaches 75°C (165°F).
