Description
When your tractor starts running hot or you notice coolant spots under the radiator, there’s a good chance that lower radiator hose is telling you it’s time for retirement. This is the hose that handles the constant flow of coolant from your radiator back to the engine block, and when it fails—usually when you’re in the middle of harvest or a critical field operation—it can shut you down fast.
What You’re Getting
- Direct replacement hose that fits like the original factory part
- Heavy-duty rubber construction that handles the heat cycles and pressure of farm work
- Proper diameter and bend angles for clean installation without kinks or stress points
- Quality TISCO manufacturing that’s built for the demands of agricultural equipment
Built for Real Farm Work
This lower radiator hose is designed for International Harvester tractors that put in serious field time. From the Hydro 100’s smooth hydrostatic operation to the reliable power of the 66 and 86 series tractors, these machines are workhorses on farms across the Midwest. Whether you’re running a corn head through the rows, pulling a disk through stubble, or pushing silage with a blade, proper cooling system function keeps you moving when time is critical.
Made to Last
Farm tractors generate a lot of heat, and cooling system hoses take the brunt of constant temperature swings, pressure changes, and engine vibration. This TISCO replacement is built with the same attention to durability as the original equipment, using materials that stay flexible in cold weather and resist cracking under summer heat.
Installation Notes
Before installing, drain the cooling system and inspect the hose clamps—replace them if they’re showing corrosion or lost their spring tension. Check that the radiator outlet and engine inlet are clean and smooth to prevent leaks. After installation, run the engine and check for proper coolant flow and any signs of leaks around the connections.
