• Appliion and Function

1.Primary Use:
This water tank is a critical component of the engine cooling system, storing coolant (a mixture of water and antifreeze) to regulate engine temperature during operation. It ensures consistent heat dissipation, preventing overheating in high-load environments (e.g., mining, construction sites).
Compatible with Komatsu machines featuring water-cooled engines (e.g., SAA6D107E-1 in the WA380-6 loader, which has a coolant capacity of 30.5 liters).

2.System Integration:
Connected to the radiator, water pump, and engine via hoses and fittings, the tank maintains coolant circulation. Its design includes a pressure cap to regulate system pressure (typically 1.1–1.3 bar) and a reserve chamber to accommodate coolant expansion.
