Clean/Flush Coolant
Do not perform this maintenance until you read and understand the material in the Safety and Cooling System Specifications sections of this publication.Caterpillar does not recommend the use of cooling system solutions that are intended to stop leaks. Use of these products may result in excessive internal deposits that could reduce the engine's heat transfer characteristics as well as damage to the water pump seals.This procedure is to be used for normal maintenance of cooling systems surfaces to return to "like new" condition. For heavy build-up of scale and deposits, a severe acid-type, commercial cleaner or mechanical cleaning will be required.
Performing maintenance on the cooling system is important because the cooling system has a direct effect on the operation and service life of the engine. Improper maintenance can result in a variety of problems that could shorten the engine's service life, reduce the efficiency of the cooling system, result in poor engine performance, and in some cases, result in an increase in fuel consumption.Add Cooling System Cleaner
There are two types of cooling system cleaners available. One is the Standard-Type and the other is the Fast Acting-Type.The Standard-Type (6V4511) requires approximately 120 hours of engine operation to remove scale, lime and other debris. The Fast Acting-Type (4C4611) requires only 90 minutes of engine operation. Both types must remain in the system for a minimum of specified time to work properly, however, neither type will harm the engine if left in for a longer period of time.The Standard-Type must be added before the Every 3000 Hour maintenance interval. Add 1 liter (1 U.S. quart) of Caterpillar Cooling System Cleaner, Standard-Type, for every 15 liter (4 U.S. gallon) of cooling system capacity. Continue to operate the engine for the specified time before draining.The Fast Acting-Type may be added just prior to draining (such as the same day) and the system cleaned and flushed after operating for the specified time period. Follow the directions on the container.Drain
When you drain, clean, flush and replace the coolant, small particles, undesirable chemicals, scale and other deposit formations are removed. These deposits reduce the necessary heat transfer characteristics of the cooling system.Coolant water drain groups, installed in the jacket water pump and radiator may be available for draining engine coolant. Contact your Caterpillar dealer for assistance.With the engine shut down and cool, use the following procedure:1. Stop the engine and allow to cool. Disable the starting system and place DO NOT OPERATE tags on the START switch on the engine control panel.2. Loosen the cooling system vent cap slowly to relieve pressure.3. Drain the system according to the requirements of your system. Check the water pump breather filter for blockage or debris and replace if necessary.Water Pump Seal
Over concentration of coolant additive (Conditioner), mineral deposits from hard water or cooling system contamination can accelerate the wear on the water pump coolant seal. The cooling system maintenance interval provides an opportunity to inspect and replace the water pump seal if necessary to reduce coolant leakage.Dispose of
