Description
Nothing ruins a good day in the field quite like an overheated tractor. Your radiator cap is the unsung hero of your cooling system, maintaining proper pressure to keep coolant flowing and prevent boil-over when you’re pushing hard through thick hay or pulling that cultivator up steep hills. When your old cap starts venting steam or won’t hold pressure anymore, this replacement gets your International running cool again.
What You’re Getting
- Proper pressure rating raises coolant boiling point by 20-30 degrees, preventing vapor formation that kills cooling efficiency
- Direct replacement design fits your radiator neck without modifications or adapters
- Professional-grade construction prevents coolant loss and maintains system pressure during cooling cycles
- Quality seal that stays flexible through temperature swings and won’t crack from vibration
Built for Real Farm Work
This cap is engineered for the International Harvester tractors that built American agriculture – your utility models like the 100, 140, 200, and 230, plus the bigger row crop machines like the 300, 330, 350, and 400 series. Whether you’re running a 460 with a loader or pushing a 650 through corn harvest, these tractors work hard and need cooling systems that can keep up.
Made to Last
These versatile machines operate in demanding conditions where reliable cooling is critical for preventing costly engine damage. This TISCO cap handles the constant pressure cycles, temperature extremes, and vibration that come with real farm work. The spring mechanism stays calibrated and the gasket maintains its seal even after thousands of heat cycles.
Installation Notes
Always let your engine cool completely before removing the old cap, check the radiator neck for damage or corrosion, and never operate without a proper cap as this can cause severe engine damage from overheating. This cap fits tractors with the standard long filler neck – if you’ve got a short neck setup, you’ll need a different part.
