Description
When your tractor starts running too hot or takes forever to warm up on cold mornings, that thermostat’s likely stuck open or closed. A failed thermostat can cook your engine or leave you shivering in the cab waiting for heat, and neither one helps get the work done. This replacement thermostat gets your cooling system regulating temperature the way it should, keeping your engine in that sweet spot for maximum power and fuel economy.
What You’re Getting
- Precise opening temperature ensures proper engine operating range
- Quality construction handles constant temperature cycling without failure
- Direct replacement design drops right into your existing thermostat housing
- Reliable seal prevents coolant leaks at the housing connection
- Built to handle the thermal stress of hard-working diesel engines
Built for Real Farm Work
This thermostat is designed for the modern diesel engines in your New Holland T6 and T7 series tractors, along with Case Puma and Maxxum models. Whether you’re running a T6.150 with a loader, pulling implements with a T7.210, or working the Puma 185 in the back forty, this thermostat maintains the proper engine temperature that these sophisticated engines need to run efficiently and meet emissions standards.
Made to Last
Farm engines work hard in dusty, dirty conditions with wide temperature swings. This thermostat is built with quality materials that won’t corrode from coolant additives or fail from constant expansion and contraction. The spring mechanism stays calibrated season after season, and the seal materials resist the chemicals in modern long-life coolants.
Good to Know
Let the engine cool completely before starting this job – hot coolant burns and pressurized systems are dangerous. You’ll lose some coolant when removing the old thermostat, so have a catch pan ready and fresh coolant on hand. Clean the housing surfaces thoroughly and use a quality gasket or sealant as specified. Test the new thermostat in hot water before installation to verify it opens properly – better to catch a defective part on the bench than after it’s installed.
