Radiator Restrictions
SMCS Code:
1353; 1396
Caterpillar discourages the use of airflow restriction
devices that are mounted in front of radiators. Airflow
restriction can cause the following conditions:
• High exhaust temperatures
• Power loss
• Excessive fan usage
• Reduction in fuel economy
If an airflow restriction device must be used, the
device should have a permanent opening directly in
line with the fan hub. The device must have a
minimum opening dimension of at least 770 cm
2
(120 in
2
).
A centered opening that is directly in line with the fan
hub is specified in order to prevent an interrupted
airflow on the fan blades. Interrupted airflow on the
fan blades could cause a fan failure.
Caterpillar recommends a warning device for the inlet
manifold temperature and/or the installation of an
inlet air temperature gauge. The warning device for
the inlet manifold temperature should be set at 75 °C
(167 °F). The inlet manifold air temperature should
not exceed 75 °C (167 °F). Temperatures that
exceed this limit can cause power loss and potential
engine damage.

Fuel and the Effect from Cold
Weather
SMCS Code:
1000; 1250
The following fuels are the grades that are available
for Cat engines:
• No. 1
• No. 2
• Blend of No. 1 and No. 2
No. 2 diesel fuel is the most commonly used fuel.
Either No. 1 diesel fuel or a blend of No. 1 and No. 2
is best suited for cold-weather operation.
Quantities of No. 1 diesel fuel are limited. No. 1
diesel fuels are usually available during the months
of the winter in the colder climates. During cold-
weather operation, if No. 1 diesel fuel is not available,
use No. 2 diesel fuel, if necessary.
There are three major differences between No. 1 and
No. 2 diesel fuel. No. 1 diesel fuel has the following
properties:
• Lower cloud point
• Lower pour point
• Lower rating of kJ (BTU) per unit volume of fuel
When No. 1 diesel fuel is used, a decrease in power
and in fuel efficiency may be noticed. Other operating
effects should not be experienced.
The cloud point is the temperature when a cloud of
wax crystals begins to form in the fuel. These crystals
can cause the fuel filters to plug. The pour point is the
temperature when diesel fuel will thicken. The diesel
fuel becomes more resistant to flow through fuel
pumps and through fuel lines.
Be aware of these values when diesel fuel is
purchased. Anticipate the average ambient
temperature of the area. Engines that are fueled in
one climate may not operate well if the engines are
moved to another climate. Problems can result due to
changes in temperature.
Before troubleshooting for low power or for poor
performance in the winter, check the type of fuel that
is being used.
When No. 2 diesel fuel is used the following
components provide a means of minimizing problems
in cold weather:
• Starting aids
• Engine oil pan heaters
• Engine coolant heaters
• Fuel heaters
• Fuel line insulation

Recommendations”.

Fuel Tanks
Condensation can form in partially filled fuel tanks.
Top off the fuel tanks after you operate the engine.
