A radiator hose carries engine coolant between the engine block and the radiator, allowing heat to be transferred away from the engine during operation. On a diesel light welder like the DLW300ES, maintaining proper coolant circulation is critical — the engine runs under sustained load while powering welding output, generating significant heat over extended use. When a radiator hose cracks, softens, or develops a leak, coolant loss occurs rapidly and the engine is at risk of overheating, leading to power loss or engine damage if the condition goes unaddressed.
