Nothing will ruin a good working day faster than a tractor that keeps overheating, especially when you're trying to finish hay before the weather turns. Your radiator cap is the unsung hero of your cooling system, and a worn-out radiator cap might not look like much, but it causes major problems. Without proper pressure, coolant boils at lower temperatures, leading to overheating and coolant loss. This replacement cap brings the proper pressure rating back to your cooling system so you can get back to work. What You're Getting Correct pressure rating and robust construction to maintain your cooling system's efficiency year after year Spring-loaded pressure release valve that protects your cooling system from damage Quality sealing gasket that prevents coolant loss and keeps air out of the system Direct replacement design that fits right on your original radiator neck Built for Real Farm Work Designed for Ferguson TE20 and other compatible models with similar radiator necks. These classic tractors have been earning their keep on farms for generations - plowing gardens, cutting hay, running PTO equipment, and handling countless other jobs around the farm. Whether you're running a Ferguson TE series or Fordson Major series tractor, this cap maintains the right system pressure to keep your coolant from boiling over during hard work. Made to Last This cap is built to handle the temperature swings and vibration that come with farm work. The internal spring is calibrated to release at the proper pressure, protecting your cooling system while maintaining efficient operation. The sealing surfaces are designed to create a tight seal that won't deteriorate from exposure to coolant and engine heat. Installation Notes Always install caps on cool engines to avoid burns from hot coolant. Check the radiator neck for damage or corrosion that could prevent proper sealing. A good cap can't seal on a damaged neck. When replacing your cap, it's smart to check your entire cooling system. Look for white or green crusty deposits indicating leaks, check coolant level and condition, and ensure your overflow system works properly. Remember that a 50/50 antifreeze mix not only prevents freezing but raises the boiling point too.
