Description
When your MF 399 starts running hot or you notice coolant puddles under the tractor, chances are it’s time to replace that upper radiator hose. This critical cooling system component carries hot coolant from the engine to the radiator, and when it fails, you’ll know it quickly. A leaking or collapsed top hose can leave you stranded in the field with an overheated engine and potential costly damage.
What You’re Getting
- Direct-fit replacement designed specifically for the MF 399 and Perkins A6.354 engines
- Heavy-duty construction handles the pressure and temperature cycling of hard farm work
- Proper diameter and shape ensures optimal coolant flow to keep your engine running cool
- Quality materials resist cracking, swelling, and deterioration from coolant and heat
Built for Real Farm Work
This hose is engineered for the MF 399, a workhorse utility tractor that’s seen decades of demanding agricultural use. Whether your 399 is powering through hay season, running a loader for material handling, or driving PTO equipment, the Perkins A6.354 engine generates serious heat that requires reliable cooling system components.
Made to Last
Farm equipment cooling systems face tough conditions – temperature swings, vibration, and exposure to chemicals and debris. This replacement hose uses quality rubber compounds and reinforcement that stand up to these challenges, maintaining flexibility and seal integrity through countless heat cycles.
Installation Notes
This is a straightforward replacement – drain the coolant, remove the old hose, and install the new one with fresh clamps. Clean the connection points thoroughly and check for corrosion on the radiator neck and thermostat housing. Take this opportunity to inspect other cooling system components while you’ve got the coolant drained.
