HOSE ASSEM 3C4420 - Caterpillar

Note: There will be an indicator lamp on the dashboard of the vehicle that is marked "AIR INLET HEATER".For detailed information on the operation of the Air Inlet Heater, refer to System Operation, "Air Inlet and Exhaust".Use the following procedure in order to start the engine:
Engage the parking brake. Place the transmission in NEUTRAL. If the vehicle is equipped with a manual transmission, depress the clutch pedal in order to disengage the flywheel clutch. This reduces transmission drag and this prevents movement of the vehicle. Depressing the clutch helps to reduce the battery drain. In cold weather, this can mean the difference between starting the engine and not starting the engine. The "CHECK ENGINE/DIAGNOSTIC" lamp will flash while the engine is cranking. The lamp should turn off after proper engine oil pressure is achieved. If the lamp fails to flash, notify your authorized Caterpillar dealer. If the lamp continues to flash, the ECM has detected a problem in the system. Refer to the Operation and Maintenance Manual, "Engine Diagnostics" topic (Operation Section).
Turn the keyswitch to the ON position. The air inlet heater can preheat the system in order to improve cold weather starting. Note: The "AIR INLET HEATER" indicator lamp will flash for a minimum of two seconds regardless of the coolant temperature. If the "AIR INLET HEATER" indicator lamp flashes for more than two seconds, wait until the indicator lamp stops flashing (approximately 30 seconds) before attempting to start the engine. If the indicator lamp continues to flash, the ECM will control the air inlet heater during a restart of the engine. Restarting the engine at this point can cause excessive white smoke.Note: A buzz may be heard while the air inlet heater is engaged. This is the sound of the fuel injectors that are being exercised in preparation for starting.
Do not engage the starting motor when flywheel is turning. Do not start the engine under load.If the engine fails to start within 30 seconds, release the starter switch or button and wait two minutes to allow the starting motor to cool before attempting to start the engine again.
Turn the keyswitch to the START position in order to crank the engine. The air inlet heater will turn ON if the sum of the coolant temperature and the inlet air temperature is less than 25 °C (77 °F). Do not push the throttle or do not hold the throttle downward while the engine is cranked. The system will automatically provide the correct amount of fuel in order to start the engine. If the engine does not start after 15 to 20 seconds of cranking, release the keyswitch. If the sum of the coolant temperature and the inlet air temperature is less than 25 °C (77 °F), the preheat for the air inlet heater will restart. Turn the keyswitch to the OFF position. Allow the starting motor to cool for two minutes. Repeat Steps 2 and 3.
Oil pressure should rise within 15 seconds after the engine starts. Do not
