Heavy Duty Radiator Cap for John Deere 9560/9660/9760/9770 STS Combines

Description

Harvest season waits for no one, and when you’re pushing through tough conditions with your combine running flat-out, the cooling system is working overtime. This heavy-duty radiator cap maintains the precise pressure your John Deere 9560, 9660, 9760, or 9770 STS needs to keep coolant from boiling over when the heat builds up. A failing cap that can’t hold pressure will leave you sitting in the field when you should be filling bins.

What You’re Getting

• Exact pressure specifications for your combine’s cooling system
• Pressure relief valve that protects against system damage while maintaining optimal pressure
• Heavy-duty construction built to handle the extreme heat and vibration combines generate
• Quality rubber seal that stays flexible through temperature cycles and coolant exposure
• Vacuum valve allows proper coolant flow from overflow tank as engine cools

Built for Real Farm Work

Whether you’re combining corn in 90-degree heat or pushing through heavy wheat stands, these STS series combines generate tremendous heat that puts your cooling system to the test. This cap is calibrated specifically for these big machines that work from dawn to dark during harvest. The 9760 and 9770 STS models especially need proper cooling system pressure to handle their increased power output.

Made to Last

Combine radiator caps take a beating from constant heat cycles, engine vibration, and exposure to coolant chemicals. This one’s built with materials that won’t crack, warp, or lose their sealing ability after thousands of hours in the field. The spring maintains proper tension season after season, and the rubber seal resists the hardening that kills cheaper caps.

Installation Notes

Always let the engine cool completely before removing the old cap – pressurized coolant can cause serious burns. Check that the radiator neck is clean and undamaged before installing the new cap. Keep a spare in your combine’s toolbox, because radiator caps have a habit of failing at the worst possible times during harvest rush.
