Upper Radiator Hose for John Deere 3010, 3020, 4000, 4010, and 4020 Series Tractors

Description

When you’re dealing with an overheating tractor or coolant puddles under your John Deere, a cracked or soft upper radiator hose is often the culprit. This replacement hose connects your radiator to the engine’s thermostat housing, carrying hot coolant to the radiator where it can cool down before heading back to the engine. It’s the kind of part that works fine for years until it doesn’t—and when it fails, you’ll know it fast.

What You’re Getting

• Direct replacement hose that fits like the original without modifications
• Heat-resistant rubber construction that handles temperature cycling from cold starts to hot field work
• Pre-formed shape maintains proper routing and clearances around engine components
• Quality construction prevents collapse under vacuum when the engine’s running hot
• Reinforced design resists cracking and splitting from engine vibration

Built for Real Farm Work

This upper hose fits the classic John Deere workhorses that built many farm operations—the 3010 and 3020 utility tractors along with the 4000, 4010, and 4020 row-crop machines. Whether your 4020 is your main field tractor, that 3020 runs the hay equipment, or the 4010 handles loader work around the farmyard, keeping these engines cool is critical to getting the job done.

Made to Last

Quality rubber compounds in this hose handle the constant heating and cooling that destroys cheaper alternatives. The reinforced walls won’t balloon or collapse under pressure changes, and the pre-formed bends ensure proper fit without kinking or restricting coolant flow.

Good to Know

Replace this hose when the engine’s completely cold—hot coolant and pressurized systems don’t mix well with maintenance work. It’s false economy to connect old hoses to a new radiator, so if you’re doing cooling system work, consider replacing both upper and lower hoses at the same time along with the clamps.
