White Smoke
Possible Causes/Corrections Cold Outside TemperaturesWhen the air outside is cold, the cylinder temperature is cooler. Not all the fuel will burn in the cylinders. The fuel which does not burn comes out the exhaust as white smoke. White smoke is normal in cold temperatures until the engine operates long enough to become warm. There will be less white smoke if No. 1 diesel fuel is used. Intake Manifold Heater Not WorkingIf dash light goes out before 60 seconds or is blinking refer to Troubleshooting in Special Instruction, SEHS9773, Installing the 1047618 Intake Manifold Heater. Long Idle PeriodsWhen an engine runs at idle speed for a long period of time, the cylinders cool and all of the fuel does not burn. Do not idle an engine for a long period of time. Stop an engine when it is not in use. If long idle periods are necessary, use No. 1 diesel fuel. Engine Operating Temperature Too LowThis can cause white smoke on startup. If the smoke is slow to clear from the exhaust, check and make a replacement of the thermostat if needed. Low Quality FuelTest the engine using fuel according to recommendations by Caterpillar Inc. For more information refer to SEBD0717, Diesel Fuels And Your Engine. Air In Fuel SystemWith air in the fuel system, the engine will normally be difficult to start, run rough, and release a large amount of white smoke. If the engine will not start, loosen a fuel injection line nut at the through the head adapter and crank the engine until fuel comes out. Tighten the fuel line nut. Start the engine. If the engine still does not run smooth or releases a large amount of white smoke, loosen the fuel line nuts one at a time at the through head adapters until the fuel that comes out is free of air. Tighten the fuel line nuts. If the air cannot be removed in this way, put 35 kPa (5 psi) of air pressure to the fuel tank.
Do not use more than 55 kPa (8 psi) of air pressure in the fuel tank or damage to the tank may result.
Check for leakage at the connections between the fuel tank and the fuel transfer pump. If leaks are found, tighten the connections or replace the lines. If there are no visual leaks, remove the fuel supply line from the tank and connect it to an outside fuel supply. If this corrects the problem, the suction line (standpipe) inside the fuel tank has a leak. Fuel Injection Timing Not CorrectCheck and make necessary adjustments as in Testing and Adjusting Section of this Service Manual. Valve Adjustment Not CorrectCheck and make necessary adjustments as in Testing and Adjusting Section of this Service Manual. Intake valve lash is 0.38 mm (.015 in) and exhaust valve lash is 0.64 mm (.025 in). Defective Fuel Nozzle(s)Defective fuel nozzles will normally cause the engine to "misfire" and run rough, but can cause too much smoke with the engine still
