197801 - Miller Replacement Radiator Assembly with 14 PSI Cap

Restore Cooling Efficiency with the Miller 197801 Radiator Assembly

Keep your Miller welding equipment running cool and efficient with the Miller 197801 Radiator. This assembly is a direct replacement part designed for specific Miller engine-driven welders and cooling units. Over time, radiators can become clogged with debris, suffer from corrosion, or sustain damage from job site hazards. A compromised radiator leads to overheating, which triggers thermal shutdowns and can cause permanent damage to your welder's engine or power source. Replacing a failing unit with this high-quality OEM radiator is the most effective way to restore your machine's reliability.

The standout feature of this unit is its 2-row core construction. Radiators with a 2-row core are designed to handle higher heat loads by passing coolant through two parallel rows of tubes. This design maximizes contact with the cooling fins, facilitating rapid heat exchange with the surrounding air. This is particularly important for welders operating in high-temperature environments or those running at high amperage for extended periods. The robust metal construction is built to withstand the vibration and mechanical stress typical of portable and engine-driven welding generators.

This product comes complete with a 14# (14 PSI) radiator cap. The cap is not just a lid; it is a pressure relief valve that maintains the system pressure necessary for efficient cooling. A worn or incorrect cap can lead to coolant loss and overheating. By including the correct 14 PSI cap, Miller ensures that the entire assembly is ready to perform immediately upon installation. The fitment is precise, aligning perfectly with factory mounting brackets and hose connections, which simplifies the repair process for technicians.

Investing in genuine Miller repair parts protects your investment. While generic radiators might look similar, they often lack the specific flow characteristics and pressure ratings required by Miller equipment. Ensure your welder is ready for the next job by installing the Miller 197801 Radiator. Please verify your machine's serial number and parts manual to confirm compatibility before ordering, as cooling systems can vary between model years and series.
