Miller Bobcat 250 Diesel Upper Radiator Hose Replacement

Keep Your Bobcat 250 Diesel Running Cool

Don't let a blown hose stop your work in the field. The Miller 223559 Hose, Radiator Upper Fill is the exact replacement part you need for your Bobcat™ 250 Diesel™ welder. When you are out on a job site, your engine-driven welder is the heart of your operation. If the cooling system fails, the machine shuts down, and work stops. This genuine Miller hose is designed to replace worn, soft, or leaking upper radiator hoses to restore your machine's cooling efficiency immediately.

Why Choose Genuine Miller Parts?

Your Bobcat 250 Diesel is a workhorse, but it relies on a complex cooling system to handle heavy welding loads. The 223559 hose is not just a piece of rubber; it is a pre-formed component shaped to navigate the tight spaces of your welder's engine bay without rubbing against hot metal or vibrating components. Universal hoses often kink when bent to these specific angles, cutting off coolant flow and cooking your engine. This OEM hose fits perfectly right out of the package, making installation quick and hassle-free so you can get back to welding.

Maintenance Tips

Radiator hoses degrade over time from the inside out. Electrolysis and heat can cause the rubber to become soft or brittle. We recommend inspecting your Bobcat's cooling system every time you change the oil. Squeeze the upper hose—if it feels spongy, crunchy, or shows signs of bulging, it's time to replace it with the Miller 223559. Replacing a hose is a cheap and easy fix compared to rebuilding a diesel engine that has overheated. Keep your equipment in top shape with parts that match the original factory specifications.

Compatibility

This hose is specifically for the Diesel version of the Bobcat 250. It connects to the upper fill neck of the radiator assembly. Trust Welders Supply for all your Miller repair parts and consumables. We help you keep your arc lit and your machines running smooth.
