Description
When you see that temperature gauge creeping up or notice coolant loss, a failing upper radiator hose is often the culprit. This molded top hose connects your radiator to the engine block, carrying hot coolant from the engine to the radiator for cooling. When it starts getting soft, cracked, or swelling, you’re looking at potential overheating that can turn expensive fast.
What You’re Getting
- 37mm diameter hose designed specifically for 40 series tractors
- Molded shape provides proper fit and flow without kinking or collapsing
- Heat-resistant construction handles the temperature cycling your engine puts it through
- Direct replacement that connects with your existing radiator like the one at QTP-58895
- Quality rubber compound that resists cracking from heat and ozone exposure
Built for Real Farm Work
This hose fits right into the cooling systems of those reliable 40 series John Deeres – the 1640, 2040, and 2140 tractors that have been workhorses on farms for decades. Whether your tractor’s running a hay baler in summer heat, pulling a plow through spring work, or powering a grain cart during harvest, proper coolant circulation is what keeps your engine running when the work gets tough.
Made to Last
This isn’t some generic hose that might work – it’s molded to the exact shape and size your 40 series needs. The rubber compound handles the heat cycles from cold startup to full operating temperature without the premature cracking you get from cheaper alternatives. The 37mm diameter ensures proper coolant flow while the reinforced construction prevents collapse under vacuum.
Installation Notes
Before installing, let the engine cool completely and drain coolant to avoid burns. Clean the connection points thoroughly and check that the radiator neck isn’t damaged. A light coating of coolant on the hose ends makes installation easier without over-lubricating. Tighten clamps evenly but don’t over-torque – you want to seal without cutting into the hose.
