When you’re running long days in the combine during harvest or pushing hard with your tractor through heavy conditions, the last thing you need is an overheating engine. A worn radiator cap might not look like much, but it’s the small part that keeps your cooling system working properly. This 7 PSI cap maintains the exact pressure your John Deere cooling system was designed for, preventing coolant from boiling over when the work gets tough.
What You’re Getting
- 7 PSI pressure rating that raises coolant boiling point for better heat protection
- “B” size design with 2-11/16″ outer diameter fits your radiator neck perfectly
- 3/4″ deep reach ensures proper sealing on your specific filler neck
- Quality construction with reliable spring and seal that won’t fail when you need it most
- Direct OE replacement – no modifications or adapters needed
Built for Real Farm Work
This cap fits a wide range of John Deere equipment from the big 9000 series tractors down to CTS combines. Whether you’re running a 9610 through heavy tillage, operating a 9750STS during a marathon harvest day, or using your tractor for loader work around the farm, this cap maintains proper cooling system pressure so your engine can handle whatever you throw at it.
Made to Last
Farm equipment cooling systems take a beating from dust, vibration, temperature swings, and chemical exposure. This radiator cap is built with materials that resist corrosion and maintain their seal through thousands of heating and cooling cycles. The spring stays calibrated and the gasket stays flexible, giving you reliable pressure control season after season.
Installation Notes
Always let your engine cool completely before removing any radiator cap – hot pressurized coolant can cause serious burns. This cap threads on just like the original, but take a moment to check the radiator neck for any corrosion or damage that could prevent proper sealing. A quick tip: if you’ve been mysteriously losing coolant, a faulty cap is often the culprit.
