Air compressor and drill engines with connected driven loads are difficult to start in cold weather. Starting of the engine is even more difficult in high altitudes.The following recommendations are given in the order of their importance.Auxiliary Heating Aids
For cold weather operation of Diesel Engines, auxiliary heating equipment is necessary. Know the type of application, expected low temperature, and make plans for auxiliary heaters before cold weather has started. To help find the level of auxiliary heaters needed, use the information below as a guide.Different starting temperatures need different levels of engine preparation before starting. This guide is given for an engine that has been given correct regular maintenance. Given below are five temperature levels.* Level (1) +50°F to +32°F (+10°C to 0°C)* Level (2) +32°F to +10°F (0°C to -12°C)* Level (3) +10°F to -15°F (-12°C to -25°C)* Level (4) -16°F to -40°F (-26°C to -40°C)* Level (5) below -40°F (-40°C)The following procedures of engine preparation for starting, are the recommendations at the five temperature levels. Fuel Heaters
a) Waxing of fuel and freezing water are the most common causes of difficult starting. A change of fuel filters and thoroughly priming the system can correct the waxing problem. Make sure water is kept out of the fuel; this is important. Fuel heaters can also be used. Suppliers of fuel heaters are: (See page 8 for complete addresses)* J/McQ Fuel Heater - Water Separator* Phillips Temro, Inc.* Webb Enterprises, Inc.* South Wind Division of Stewart Warner CorporationTypes Of Auxiliary Heating Aids
Electric
If 110 or 220 volt (50 or 60 Hz) current is available, electric heaters can be used. There are two types of electric water heaters for engines:Immersion Water Heaters
a) The in-block immersion water heaters are available from Caterpillar dealer parts departments. They are made to keep an engine warm after it has been shut down. Normal procedure is to put the unit near an electrical power supply to keep the engine warm until it is started again. These heaters are not made to heat a cold engine. They are installed in the cylinder block core plugs or oil cooler connections.b) The chart below gives engine displacement, weight, thermostat opening temperature and water volume that should be sent to suppliers when heaters are ordered. Available heaters from Caterpillar dealers are: b) Other suppliers of immersion heaters are: (see page 8 for complete addresses) * Phillips Temro Inc.* Kim Hotstart Manufacturing Co.The pictures below give the element installation location for in-block immersion water heaters. a) Right side location for 3208 Engine. b) Left side location for 3208 Engine. Do not damage the bore when the core plug is removed. c) Element location for 3300 Series Engine. d) Element location for 3406 Engine. e) Right side location for 3408 and 3412 Engines. f) Left side location for 3408 and 3412 Engines. Remove the cover and install a 7N210 Adapter.Tank Water Heaters
a) Tank water heaters use a location outside the engine and need electrical power. The difference in temperature moves the water from
