Description
When you start seeing steam or notice your temp gauge climbing higher than it should, a failing radiator cap is often the culprit. This 13 PSI cap maintains proper pressure in your cooling system, which keeps coolant from boiling over and helps your engine run at the right temperature. A good seal is what stands between you and an expensive overheating problem.
What You’re Getting
- OE-type pressure cap that maintains proper 13 PSI system pressure for efficient cooling
- Deep neck design fits 3/4 inch radiator necks found on these John Deere models
- Built for overflow reservoir systems that cycle coolant as temperatures change
- Direct replacement that restores proper cooling system operation
Built for Real Farm Work
This cap fits a wide range of John Deere compact and utility tractors from the smaller 330 and 430 models up through the 950 and 955 machines, plus newer models like the 3320, 5105, and 5320. These are the tractors you’ll find mowing pastures, running bush hogs, operating loaders, and handling the day-to-day chores that keep a farm running.
Made to Last
Farm tractors generate plenty of heat, especially when you’re pushing them hard in summer conditions or working with heavy implements. This cap’s spring-loaded pressure valve and rubber seals are designed to handle the constant heating and cooling cycles that come with real farm work, maintaining a tight seal season after season.
Good to Know
Always let the engine cool completely before removing the old cap – hot coolant under pressure can cause serious burns. Check your coolant level while you’re replacing the cap, and look for any debris or corrosion around the radiator neck that might prevent a good seal.
