COLD WEATHER OPERATION

DANGER
Do NOT, under any circumstances, use starting fluid (ether) on engine whether or
not equipped with an inlet manifold air heater element. An explosion can occur.

Cold Weather Starting Tips

• Save the batteries. Do not overtax the batteries by cranking the starter for
more than 30 seconds without interruption. Allow about two minutes between
attempts at starting the vehicle; this allows the starter to cool and the batteries
to re-energize.
Note: Always make sure that the battery is fully charged in cold weather.
• Use the correct grade of oil for the prevailing winter temperature.
• Drain the fuel tanks and filters regularly to prevent water accumulation in the
fuel system. This accumulation can freeze in fuel tanks, fuel lines and filters.
WARNING
Do NOT — under any circumstances — add gasoline, alcohol, used oil or
additives with metallic particles to the fuel.
• If the fuel gels and starts clogging filters and small passages, mix a small
percentage of No. 1D fuel (kerosene) with No. 2D (diesel) fuel.
Note: Adding kerosene is NOT recommended for general use because both
performance and fuel economy will be reduced.
• Refer to the Maintenance and Lubrication Manual for additional cold weather
operating information.
