Change Coolant
At operating temperature, engine coolant is hot and under pressure.Check coolant level only when engine is stopped and radiator filler cap is cool enough to touch with your bare hand.Remove radiator filler cap slowly to relieve pressure.Steam can cause personal injury.Cooling System Conditioner contains alkali. Avoid contact with skin and eyes to prevent personal injury.Use all cleaning solutions with care.
All water is corrosive at engine operating temperature. Use Caterpillar Cooling System Conditioner to treat either approved plain water or ethylene glycol solution.Do not use Caterpillar Cooling System Conditioner or Coolant Conditioner Elements with Dowtherm 209 Full-Fill coolant. Follow recommendations provided with Dowtherm 209 Full-Fill coolant.If the engine is to be shipped to, or stored in, an area with temperatures below 0°C (32°F), the cooling system must be protected to the lowest expected ambient temperature.Clean the cooling system if there is a scale buildup, oil in the coolant, if the coolant is muddy, if engine overheating or foaming is observed. Refer to "Clean the Cooling System."
Typical Example1. Remove the radiator filler cap slowly to relieve pressure. 2. Remove the drain plug on bottom of water pump housing. 3. Remove the two block drain plugs from both sides of the engine. Allow coolant to drain.4. Clean and install all drain plugs.5. Fill the system with a solution of approved water, antifreeze and .5 liter (1 pint) of Caterpillar Cooling System Conditioner for each 15 liters (4 U.S. gallons) of coolant added. See "Refill Capacities" for amount of solution needed.Add solution slowly at 20 liters (5 U.S. gallons) or less per minute to avoid air locks.6. Start the engine with the radiator filler cap off. Operate the engine until the thermostat opens and coolant level stabilizes. Fill the cooling system to the bottom of fill tube. Install the radiator filler cap.Clean the Cooling System
1. Remove the radiator filler cap slowly to relieve pressure.2. Remove the water pump and block drain plugs. Allow coolant to drain. Install the drain plugs when all of solution is drained.3. Fill the cooling system with a cleaning solution. Use a commercially available cleaner or 1 kg (2 lb.) sodium bisulfate per 38 liters (10 gal.) of water.4. Start and operate engine for 1/2 hour. Stop engine, remove drain plug and drain the cleaning solution.5. With the engine stopped, flush the system with water until draining water is clear.6. Install the drain plugs. Fill the system with a neutralizer. Use a commercially available neutralizer or 250 grams (1/2 lb.) sodium carbonate crystals per 38 liters (10 gal.) of water.7. Operate engine for ten minutes. Stop the engine, remove drain plug and drain the neutralizer.8. With the engine stopped, flush the system with water until drain water is clear. Install the drain plugs.9. Fill the system with clean water and operate the engine for five minutes. Remove the drain plugs, drain the cooling system and install the drain plugs.10. Repeat Step 9 until water drained is clear.11. Mix a solution of water, antifreeze and cooling system conditioner. See "Refill Capacities" for amount of coolant needed.12. Start and operate the engine with the radiator filler cap removed until the thermostat opens and the coolant level stabilizes. Fill the system to the bottom of fill tube.13. Stop the engine.14. Install the radiator filler cap.
