Description
When your cooling system starts building too much pressure, you need a cap that’ll save your radiator from cracking and your engine from overheating. This safety release radiator cap keeps pressure at exactly 7 PSI – not too high to damage old cooling system components, but enough to raise your coolant’s boiling point and keep things running cool when you’re working hard.
Key Features
- 7 PSI pressure rating raises coolant boiling point for better heat management
- Safety release design prevents dangerous over-pressurization that can crack radiators
- Fits 3/4-inch deep filler necks – just measure your radiator neck to confirm
- Quality construction handles temperature cycling and vibration season after season
Built for Real Farm Work
This cap fits a solid range of workhorse tractors – everything from mid-sized utility machines to larger row-crop models. Whether you’re running a 2155 on hay ground, pushing a 4425 through heavy tillage, or using a 5400 for loader work, these are the tractors that do the real work on farms across the country.
Made to Last
The safety release mechanism is calibrated to open at the right pressure, protecting your cooling system from damage while maintaining efficient operation. Quality materials resist corrosion from coolant exposure and won’t deteriorate over time like cheap alternatives that fail when you need them most.
Good to Know
Before installing, make sure you’ve got that 3/4-inch deep neck – this won’t seal properly on shallow necks. Always let the engine cool completely before removing any radiator cap to avoid burns from hot coolant. If your old cap has been stuck for years, a little penetrating oil around the threads helps.
