Description
When your Fiat 90 series tractor starts leaving coolant puddles where it’s parked or you catch that telltale sweet smell of antifreeze in the air, your thermostat housing might be calling it quits. This critical piece of your cooling system holds the thermostat in place and directs coolant flow between the engine and radiator, keeping your diesel engine running at just the right temperature for peak performance and fuel efficiency.
What You’re Getting
- Precision-cast housing that provides proper coolant flow channels for optimal temperature control
- Durable construction designed to resist cracking and corrosion from heat cycles and coolant chemicals
- Direct replacement part that fits exactly like the original factory component
- Correct mounting points and hose connections for hassle-free installation
Built for Real Farm Work
This housing is engineered specifically for Fiat 90 series tractors, including the 90-90, 100-90, 110-90, 115-90, 130-90, and 140-90 models. Whether you’re running a utility 90-90 for loader work around the homestead or pushing a 140-90 hard through long field days, proper cooling keeps these reliable engines delivering the power you need season after season.
Made to Last
Farm tractors face temperature extremes, constant vibration, and coolant that’s loaded with corrosion inhibitors and anti-freeze chemicals. This housing is built from materials that handle these conditions without cracking or deteriorating, ensuring a leak-free seal that maintains proper cooling system pressure and flow.
Installation Notes
Drain your cooling system completely before starting this job—hot coolant will burn you in a hurry. Clean all the old gasket material off the mating surfaces, and while you’ve got the cooling system apart, it’s smart to install a new thermostat and gasket too. Check your radiator hoses while you’re at it—if the housing failed from age, those hoses are probably due for replacement as well.
