197822 - Miller 197822 Radiator Assembly with 14lb Cap and 3-Row Core

Premium Cooling for Miller Equipment

The Miller 197822 Radiator is a critical replacement component designed to restore and maintain the thermal efficiency of your industrial welding equipment. Engineered specifically for Miller engine-driven welders and cooling systems, this radiator features a robust 3-row core design. Unlike standard single or double-row cores, a 3-row configuration offers significantly increased surface area. This expanded surface area allows for more effective heat transfer, ensuring that coolant fluid is rapidly brought down to optimal temperatures even during long duty cycles in hot environments. Overheating is a primary cause of equipment failure in the field; installing a high-capacity radiator like this one is the best defense against thermal breakdown.

This assembly comes ready for installation with a 1.125-inch inlet and outlet. These standard-sized ports are precision-machined to ensure a leak-free seal with your existing cooling hoses. Proper flow rate is essential for the longevity of both the water pump and the engine block, and this OEM part guarantees that flow restrictions are kept to factory specifications. The unit is built to withstand the vibration and rough handling often encountered on job sites, featuring durable soldering and high-quality metal construction that resists corrosion and fatigue over time.

Included with the radiator is a 14# (14 psi) pressure cap. The pressure cap is a vital, often overlooked, component of the cooling system. By maintaining the system at 14 psi, the boiling point of the coolant is raised, preventing boil-over during heavy load operations. Using the correct cap is just as important as the radiator itself, and Miller includes it here to ensure the entire pressure vessel operates exactly as intended. Whether you are repairing a leak, replacing a clogged unit, or performing a complete overhaul of an older machine, this kit provides the essential hardware needed to get your welder back up and running.

Choosing genuine Miller OEM parts like the 197822 ensures compatibility and performance. Aftermarket radiators may not align perfectly with mounting brackets or fan shrouds, leading to installation headaches and potential modification requirements. This unit is designed to drop directly into place, minimizing downtime and labor costs. Protect your investment and ensure consistent arc performance by keeping your power source cool with this premium replacement radiator.
