Description

When your Fiat starts running a little warmer than usual or you notice coolant puddles where you park, it’s often the expansion tank that’s given up the fight. This handy part works alongside your radiator to manage coolant expansion and keep air out of the system—something that becomes critical when you’re working your tractor hard during harvest or putting long hours on the loader.

What You’re Getting

Direct replacement tank that handles coolant expansion without leaks or air pockets
Durable construction designed to handle pressure cycling and temperature extremes
Proper venting system that prevents vacuum formation during cool-down
Compatible design that works with the related radiator system

Built for Real Farm Work

This expansion tank fits a wide range of Fiat tractors from the utility 66 series up through the powerful 90 series and includes the L and Winner series models. Whether you’re running hay equipment, pulling tillage tools, or doing loader work around the farm, these are the mid-range workhorses that handle everyday chores without complaint—as long as you keep them cool.

Made to Last

Farm tractors see temperature swings that would kill most automotive cooling systems. This tank is built to handle those conditions, with materials that resist cracking from pressure cycling and construction that won’t leak when coolant gets hot and expands. It’s designed to work with your existing radiator and maintain proper system pressure through season after season of hard use.

Installation Notes

This is a direct replacement that bolts in just like the original. Before installation, flush the cooling system thoroughly and check all hoses—old coolant and deteriorated hoses will contaminate a new tank quickly. Always let the system cool completely before starting work, and refill with the proper 50/50 coolant mixture your Fiat’s engine needs.
