Description

When your Case tractor starts running hot or you notice coolant loss around the radiator, a worn-out cap is often the culprit. Your radiator cap does a lot more than just keep dirt out of the cooling system—it maintains the pressure that keeps your coolant from boiling over during hard work. This OE type radiator cap operates at 4 psi and gets your cooling system back to working like it should.

What You’re Getting

Proper “B” size fit with 2-11/16″ OD that matches your original equipment
Designed for 3/4″ deep filler necks found on these Case models
Heavy duty construction built to handle the vibration and temperature swings of farm work
Spring-loaded pressure release that protects your cooling system from over-pressurization
Quality seal that prevents coolant loss and keeps contaminants out

Built for Real Farm Work

This cap fits Case tractors including the 730, 830, 930, 1030, 1470, and 2470 models. These are solid workhorses that handle everything from hay work to heavy field cultivation, and they generate serious heat when you’re pushing them. The right pressure cap is essential for keeping these engines cool when the work gets tough.

Made to Last

Farm work is hard on cooling systems, and cheap caps fail when you need them most. This heavy duty replacement features robust construction that stands up to temperature extremes, constant vibration, and the corrosive effects of coolant. The spring mechanism stays calibrated to release at the proper pressure, protecting your system while maintaining efficient cooling.

Installation Notes

Always install on a cool engine to avoid burns from hot coolant or steam. Check the radiator neck for damage, corrosion, or buildup that could prevent proper sealing—a good cap can’t seal on a damaged neck. When you’ve got the old cap off, it’s a perfect time to check your coolant level and condition. Remember that a 50/50 antifreeze mix not only prevents freezing but also raises the boiling point for better cooling performance.
