Description
When your John Deere’s cooling system starts acting up, the bottom radiator hose is often the first place to look. This hose carries coolant through the radiator and back through the engine to keep it operating at an optimal temperature. A cracked or worn bottom hose can leave you stranded in the field with an overheating tractor—something no farmer has time for during busy seasons.
What You’re Getting
- 54mm diameter hose designed specifically for your 20 and 30 series tractors
- Durable construction that handles the pressure and temperature swings of daily operation
- Direct replacement that fits exactly like the original factory hose
- Flexible design that absorbs engine vibration without cracking
Built for Real Farm Work
These compact John Deere tractors are workhorses on smaller farms and specialty operations. Whether you’re using your 3120 for loader work around the yard, running a finish mower with your 3030, or handling light tillage with the 3130, proper cooling keeps your engine running strong through long days.
Made to Last
Radiator hoses live in a tough environment with constant heat cycles and coolant chemicals. This hose uses quality rubber compounds that resist cracking from ozone exposure and stay flexible even in cold weather startup conditions.
Installation Notes
Replace both the top and bottom hoses at the same time if one’s gone bad—they’ve both seen the same stress and age. Drain the coolant first, and this is a perfect time to flush the system and check your thermostat while you’ve got things apart.
