This radiator puts your tractor back to full cooling capacity, so you can tackle those long days without watching the temperature gauge climb. Whether yours is leaking, clogged beyond saving, or just worn out from years of faithful service, a new radiator means peace of mind when the work gets demanding.

Built for Real Farm Work
Your 1640, 1840, 2040, 2040S, or 2140 is a dependable workhorse that’s probably seen everything from hay operations to row crop cultivation. These tractors get pushed hard in hot conditions – exactly when cooling becomes critical. This radiator handles the heat load whether you’re pulling through tough ground or running a PTO-driven implement all day.
Made to Last
The multi-row core design gives you maximum cooling surface area while maintaining the structural strength to handle farm conditions. Tubes and fins are engineered to transfer heat efficiently while resisting the debris and vibration that comes with real fieldwork.
Good to Know
Radiator replacement is straightforward maintenance that protects your entire engine investment. Work with a cool engine and have coolant containers ready. This is the perfect time to inspect hoses, belts, and other cooling components – replace anything marginal now rather than risk a breakdown with your new radiator installed. Use proper 50/50 coolant mix and follow bleeding procedures to eliminate air pockets that cause hot spots.
