Description

If you’ve noticed coolant puddles under your tractor or your temperature gauge creeping higher than usual, it might be time to check your upper radiator hose. This critical cooling system component carries hot coolant from your engine to the radiator, and when it starts to fail, you’ll know it – either through leaks, overheating, or that spongy feeling when you squeeze an aging hose. Don’t wait until you’re stuck in the field with an overheated engine.

What You’re Getting

Direct replacement upper radiator hose with 49mm connection for proper fit
Heat-resistant construction that handles high-temperature coolant without deteriorating
Reinforced design prevents collapse under pressure and vacuum conditions
Quality rubber compound resists cracking from temperature cycles and ozone exposure
Pre-formed shape eliminates kinks and maintains proper coolant flow

Built for Real Farm Work

This hose connects the hot side of your cooling system on John Deere 40 series tractors – machines known for their reliability in demanding farm applications. Whether you’re running a 3040 on the loader all day, pulling heavy equipment with your 4040, or working your 3140 through long field days, these tractors generate serious heat that demands a cooling system that works without fail.

Made to Last

Radiator hoses live in one of the harshest environments on your tractor – constant heat cycles, pressure changes, and exposure to chemicals and ozone that break down inferior rubber. This replacement hose uses quality compounds that resist the deterioration that causes unexpected cooling system failures when you can least afford them.

Good to Know

Before installation, drain your cooling system and inspect the radiator neck and thermostat housing for damage or corrosion. Clean the connection points thoroughly – old coolant residue prevents proper sealing. Use quality constant-tension clamps that maintain pressure as the hose ages. When refilling, bleed air pockets completely and check for leaks before putting the tractor back to work.
