224368 - Miller Bobcat 250 Diesel Coolant Recovery Tank & Bracket

Genuine Miller 224368 Coolant Overflow Bottle and Bracket

The Miller 224368 is a critical replacement component designed exclusively for the Miller Bobcat 250 Diesel Engine Driven Welder/Generator. This kit includes both the coolant overflow bottle and the specific mounting bracket required for secure installation. As a genuine Miller Electric part, it guarantees a perfect fit and seamless integration with your existing equipment, eliminating the guesswork often associated with aftermarket or universal replacements.

Engine-driven welders like the Bobcat 250 Diesel generate significant heat during operation. The liquid cooling system is vital for maintaining optimal engine temperature and performance. The coolant overflow bottle, also known as an expansion tank or recovery reservoir, plays a key role in this system. As the engine heats up, the coolant expands and pressure builds; the overflow bottle captures this expanding fluid, preventing it from being lost to the ground. When the engine cools down, the fluid is drawn back into the radiator. A cracked, leaking, or missing overflow bottle can lead to coolant loss, air pockets in the cooling system, and ultimately, engine overheating which can cause catastrophic damage to your welder.

This assembly is built to withstand the rigorous environment of industrial welding sites. The bottle is constructed from durable, heat-resistant materials capable of enduring the thermal cycles of the diesel engine, while the bracket is designed to resist vibration and corrosion. Replacing a damaged reservoir is a proactive maintenance step that protects your investment. Whether your original bottle has become brittle with age, cracked due to impact, or the bracket has fatigued, the Miller 224368 restores the integrity of your cooling system.

Installation is straightforward as this is a direct OEM replacement. It connects directly to the radiator overflow hose and mounts to the chassis using the factory mounting points. By choosing genuine Miller parts, you ensure that your Bobcat 250 Diesel continues to deliver the reliability and performance you expect from a top-tier welder generator. Keep your equipment running cool and efficient with this essential repair part.
