107692-5170 ZEXEL 9 400 612 146 BOSCH INJECTION-PUMP ASSEMBLY 9400612146 1076925170 16714z5662

You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures.Cooling System (Extended Life Coolant Only)
Drain/Flush/Replace Coolant
Only clean water is needed to clean and flush the cooling system when ELC is drained and replaced.Drain
1. Stop the engine and allow the engine to cool. Loosen the coolant filler cap slowly to relieve any pressure, and remove the cap.2. Open the cooling system drain valve (if equipped). If not equipped with a drain valve, remove the engine block drain plug. Remove the oil cooler drain plug. Remove the drain plug from the bottom of the water pump housing. 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 disposal and recycling of used coolant, contact your Caterpillar dealer or contact Caterpillar Service Technology Group:Outside Illinois: 1-800-542-TOOLInside Illinois: 1-800-541-TOOLCanada: 1-800-523-TOOLFlush
3. Flush the cooling system with clean water to remove any debris.4. Close the drain valve (if equipped). Clean the drain plugs. Clean the drain plug receptacles. Install the drain plugs. Refer to the Torque Specifications section in this manual.5. Fill the cooling system with clean water. Install the filler cap. Operate the engine until the temperature reaches 49 to 66°C (150 to 120°F).6. Stop the engine and allow the engine to cool. Loosen the cooling system filler cap slowly to relieve any pressure, and remove the 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.7. Repeat steps 5 and 6.Fill
8. Fill the cooling system with ELC. Refer to the refill capacities chart in this manual for the amount of ELC needed to refill your system.9. Start and run the engine with the filler cap removed. Allow the ELC to warm, the thermostat to open, and the coolant level to stabilize. Add ELC if necessary to bring the coolant to the proper level.10. Clean the filler cap. Clean the filler cap receptacle. Inspect the filler cap gasket. If the gasket is damaged, discard the old filler cap and install a new filler cap. If the gasket is not damaged, use a 9S-8140 Pressurized Pump Group to pressure test the filler cap. The correct filler cap pressure is stamped on the face of the filler cap. If the filler cap does not hold the correct pressure, install a new filler cap.11. Install the filler cap. Start the engine. Inspect for coolant leaks and proper operating temperature.
