Use of commercially available cooling system cleaners may cause damage to cooling system components. Use only cooling system cleaners that are approved for Caterpillar engines.
A good time to inspect the water pump, replace the water temperature regulator and replace hoses is after the cooling system has been drained. Inspect the water pump and replace the water temperature regulator and the hoses, if necessary.Drain
1. Stop the engine and allow the engine to cool. Loosen the cooling system filler cap slowly in order to relieve any pressure. Remove the cooling system filler cap.2. Open the cooling system drain valve (if equipped). If the cooling system is not equipped with a drain valve, remove the drain plugs. Open the cab heater valve to drain coolant from the cab heater.Allow the coolant to drain.
Dispose of used engine coolant properly or recycle. Various methods have been proposed to reclaim used coolant for reuse in engine cooling systems. The full distillation procedure is the only method acceptable by Caterpillar to reclaim the used coolant.
For information regarding the disposal and the recycling of used coolant, consult your Caterpillar dealer or consult Caterpillar Service Technology Group:Outside Illinois: 1-800-542-8665Inside Illinois: 1-800-541-8665Canada: 1-800-523-8665Flush
1. Flush the cooling system with clean water in order to remove any debris.2. Close the drain valve (if equipped). Clean the drain plugs. Install the drain plugs. Refer to the Operation and Maintenance Manual, "Torque Specifications" in the Maintenance Section for more information on the proper torques.
Fill the cooling system no faster than 19 L (5 US gal) per minute to avoid air locks.
3. Fill the cooling system with a mixture of clean water and Caterpillar Fast Acting Cooling System Cleaner. Add .5 L (1 pint) of cleaner per 15 L (4 US gal) of the cooling system capacity. Install the cooling system filler cap.4. Start and run the engine at low idle for a minimum of 30 minutes with a coolant temperature of at least 82° C (180° F).5. Stop the engine and allow the engine to cool. Loosen the cooling system filler cap slowly in order to relieve any pressure. Remove the cooling system filler cap. Open the drain valve (if equipped) or remove the cooling system drain plugs. Allow the mixture to drain. Flush the cooling system with clean water. Close the drain valve (if equipped). Clean the drain plugs. Install the drain plugs. Refer to the Operation and Maintenance Manual, "Torque Specifications" in the Maintenance Section for more information on the proper torques.Cooling Systems With Heavy Deposits Or Plugging
For the following procedure to be effective, there must be some active flow through the cooling system components.1. Flush the cooling system with clean water in order to remove any debris.2. Close the drain valve (if equipped). Clean the drain plugs. Install the drain plugs. Refer to the Operation and Maintenance Manual, "Torque Specifications" in the Maintenance Section for more information on the proper torques.
Fill the cooling system no faster than 19 L (5 US gal) per minute to avoid air locks.
3. Fill the cooling system with a mixture of clean water and Caterpillar Fast Acting Cooling System Cleaner. Add .5 L (1 pint) of cleaner per 3.8 to 7.6 L (1 to 2 US gal) of the cooling system capacity. Install the cooling system filler cap.4. Start and run the engine at low idle for a minimum of 90 minutes. The coolant temperature should be at least 82° C (180° F).5. Stop the engine and allow the engine to cool. Loosen the cooling system filler cap slowly in order to relieve any pressure. Remove the cooling system filler cap. Open the drain valve (if equipped) or remove the cooling system drain plugs. Allow the water to drain. Flush the cooling system with clean water. Close the drain valve (if equipped). Clean the drain plugs. Install the drain plugs. Refer to the Operation and Maintenance Manual, "Torque Specifications" in the Maintenance Section for more information on the proper torques.Fill
Fill the cooling system no faster than 19 L (5 US gal) per minute to avoid air locks.
1. Fill the cooling system with coolant/antifreeze. Refer to the Operation and Maintenance Manual, "Cooling System Specifications" in the Maintenance Section for more information. Do not install the cooling system filler cap.2. Start and run the engine with the cooling system filler cap removed. Allow the coolant to warm, the water temperature regulator to open and the coolant level to stabilize. Stop the engine.3. Check the coolant level. Maintain the coolant level within 13 mm (.5 inch) below the bottom of the pipe for filling. Maintain the coolant level within 13 mm (.5 inch) to the proper level on the sight glass (if equipped).4. Clean the cooling system filler cap. Inspect the cooling system filler cap gasket. If the cooling system filler cap gasket is damaged, discard the old cooling system filler cap and install a new cooling system filler cap. If the cooling system filler cap gasket is not damaged, use a 9S-8140 Pressurizing Pump in order to pressure test the cooling system filler cap. The correct pressure for the cooling system filler cap is stamped on the face of the cooling system filler cap. If the cooling system filler cap does not retain the correct pressure, install a new cooling system filler cap.5. Start the engine. Inspect the cooling system for leaks and for proper operating temperature.
