Description
If you’ve noticed coolant spots on the ground or your engine running hotter than it should, your radiator cap might be the culprit. That little cap does a big job – it keeps your cooling system pressurized so coolant doesn’t boil over when you’re working hard on hot days. When caps get old, they stop sealing properly and let pressure escape, which means trouble for your engine.
What You’re Getting
- Proper pressure rating that keeps coolant from boiling at working temperatures
- Quality seal that prevents coolant loss and keeps air out of the system
- Spring-loaded pressure release valve that protects against system damage
- Durable construction built to handle the temperature swings and vibration of farm work
- Direct replacement – no modifications needed
Built for Real Farm Work
This cap fits those legendary Ferguson TO-series tractors (TO20, TO30, TO35) and early Massey Ferguson models (MF50, MF135, MF150) that farmers have relied on for decades. Whether your tractor’s got the original gas engine or you’re running diesel, this cap handles both setups. These are the kind of tractors you see still working – pulling brush hogs, running hay equipment, or handling loader work around the farm.
Made to Last
Farm equipment takes a beating from heat, cold, and constant vibration. This cap’s built with a robust pressure spring and quality sealing material that won’t deteriorate from coolant exposure or compress over time. It maintains the right pressure to raise your coolant’s boiling point so your engine stays cool even during heavy work.
Installation Notes
Always let the engine cool completely before removing the old cap – even a lukewarm radiator can have dangerous pressure. Check the radiator neck for cracks or corrosion while you’ve got the cap off, and clean any debris from the sealing surface. A quick tip: when you replace the cap, it’s smart to check your coolant level and condition too.
