OIL COOLER AND LINES 5P9639 - Caterpillar

See Gas Engines Application and Installation Guide, LEBW4980 for more information on the following topics:
Recommendations for the size and installation of jacket water heaters and oil heaters
Requirements for cranking torque and air starting motors at various temperaturesConsult your Caterpillar dealer for more information on the starting aids that are available for cold weather starting.Jacket Water Heaters
Jacket water heaters are available as optional equipment. Jacket water heaters are recommended for improving startability in ambient temperatures below 21 °C (70 °F). These heaters are recommended for all installations that have automatic starting.Lubricating Oil Heaters
Note: Oil pan immersion heaters are not recommended for heating the lube oil. To ensure the compatibility of the components, only use equipment that is recommended by Caterpillar.
Heating elements that are in direct contact with the lubricating oil can cause coking of the oil.To aviod coking of the oil when the oil is heated, follow these recommendations:The temperature of the heating surface must not exceed 150 °C (300 °F). The maximum heat density of the heating surface must not exceed 1.24 w/cm2 (8W/in2).
Oil viscosity affects the amount of torque that is needed to crank the engine. Oil temperatures below 10 °C (50 °F) require cranking torque that is excessive. Oil heaters are recommended for heating the lube oil to 10 °C (50 °F) when the ambient conditions are below this temperature.Requirements for Starting with Air
To start the engine at colder temperatures, a larger volume of starting air and/or a higher air pressure is necessary. Ensure a sufficient supply of air pressure for cold weather starting. Do not exceed the maximum air pressure for the starting motor.Water Separator
Condensation of vapor in the air supply can freeze in cold weather. This can enable the following problems to occur:
Ice that forms in the supply lines will restrict the air supply.
If particles of ice enter the inlet of the starting motor, the starting motor can be damaged.A water separator removes vapor from compressed air prior to the air storage tank. Dry air is required for cold weather in order to help prevent ice from forming in the supply lines.
