Description

When you see that temperature gauge creeping up during long tillage days or notice coolant puddles under your tractor in the morning, it’s time to face facts—your radiator’s calling it quits. These classic John Deere 40 and 50 series tractors have been the backbone of American farming for decades, but even the best cooling systems eventually wear out. Don’t gamble with expensive engine damage when this direct replacement can get you back to work.

What You’re Getting

Direct replacement that fits without modifications or custom brackets
Multi-row cooling core that maximizes heat transfer while handling vibration and debris
Reinforced header tanks built to resist the stress cracking that kills older radiators
Modern corrosion-resistant construction that outlasts original equipment
Proper mounting points and connections for hassle-free installation

Built for Real Farm Work

This radiator fits both 40 and 50 series John Deere tractors including models 1040, 1140, 2040, 2240, 840, 940, 1350, 1550, 1750, and 1850. Whether you’re running a utility tractor on loader work, pulling a chisel plow through heavy ground, or operating PTO equipment all day, these machines need reliable cooling to keep up with the workload you throw at them.

Made to Last

This radiator uses quality construction designed to dissipate heat efficiently while standing up to the vibration and impacts that come with field work season after season. The robust construction features multiple cooling rows that maximize heat transfer while standing up to punishment, with fin design that promotes airflow while resisting damage from chaff and debris.

Installation Notes

Start with a cool engine and drain everything completely. While you’ve got the old one out, check all the hoses—it’s foolish to connect old, cracked hoses to a fresh radiator. Clean any debris buildup and inspect mounting rubbers. Use proper coolant mixture, not straight water, and bleed air pockets carefully. The whole job takes a few hours with basic tools and saves you from costly engine repairs down the road.
