This small but crucial gasket keeps coolant sealed tight where it belongs, preventing expensive engine damage and keeping you running when the work can’t wait.
What You’re Getting

Built for Real Farm Work
This gasket is designed for John Deere’s popular 6010, 6020, and 6030 series tractors—the workhorses you rely on for everything from tillage to hay work. Whether you’re running a 6420 in the fields or using a 6930 for heavy lifting, these engines work hard and generate heat, making a reliable thermostat housing seal essential for keeping coolant where it should be.
Made to Last
Farm equipment cooling systems face constant temperature swings, vibration, and pressure changes. This gasket handles those conditions without breaking down, maintaining its seal through season after season of demanding work. It’s built to the same specs as the original, so you get reliable sealing that won’t let you down during critical farming windows.
Good to Know
Replace this gasket any time you’re working on the thermostat or cooling system—it’s cheap insurance against future leaks. Use fresh coolant and a new gasket for best results. Make sure the housing surface is clean and smooth before installing the new gasket, and don’t overtighten the housing bolts or you’ll damage the seal.
