Description
When your tractor starts running hot during those long days in the field, you know cooling problems need fixing fast. Nothing ruins a productive day like an overheating engine, especially when you’ve got work waiting. This 4-row radiator assembly is designed to keep your 4000 or 4020 John Deere running at proper operating temperature, whether you’re plowing, disking, or pulling heavy implements.
What You’re Getting
- Four-row core design maximizes heat transfer for efficient cooling under load
- Proper 24-3/8″ height and 19-1/2″ width dimensions for direct fitment
- 10 FPI (fins per inch) construction provides optimal airflow and heat dissipation
- Built to OEM specifications for tractors without factory air conditioning
- Durable construction that handles the vibration and stress of field work
Built for Real Farm Work
This radiator fits John Deere 4000 tractors and both early and late production 4020 tractors (prior to serial number 200999 and serial number 201000 and up). These are the workhorses you’ll find on farms everywhere—pulling chisel plows in spring, running balers in summer, and handling heavy tillage work when conditions are right. Whether you’re working a 4000 on a smaller operation or pushing a 4020 through heavy ground, reliable cooling isn’t optional.
Made to Last
Farm radiators face dust, debris, chaff, and temperature extremes that would kill automotive parts quickly. This radiator uses materials and construction designed to handle agricultural conditions. The four-row design provides extra cooling capacity for those hot summer days when you’re working hard, while the robust construction stands up to the constant vibration of diesel engines and rough field conditions.
Good to Know
Installation requires draining your cooling system and typically takes a few hours. While you’ve got things apart, it’s smart to check your water pump, hoses, and thermostat—cooling system components often wear together. Make sure to bleed all air from the system when refilling, and use proper coolant mixture for best protection. Check your serial number to confirm fitment, as there were running changes during 4020 production.
