1.Engine Overheating Prevention: The most vital function. By dissipating heat, it keeps the engine below its maximum safe temperature (typically 105°C/221°F), avoiding damage like warped cylinder heads, seized pistons, or cracked blocks.
2.Consistent Engine Performance: Diesel engines (like the SAA6D107E) lose power and fuel efficiency when overheated. The radiator ensures the engine stays within its optimal temperature range for full torque output (e.g., when lifting heavy loads).
3.Coolant Storage & Protection: The integrated tank eliminates air pockets in the cooling system (which cause overheating) and protects coolant from contamination by sealing the system from dirt and debris.
4.Vibration Resistance: Mounting brackets with rubber gaskets absorb engine and machine vibration, preventing damage to the radiator’s aluminum core (which is prone to cracking from constant shaking).
