Description

When you’re running a 300+ horsepower tractor through 12-hour days, your cooling system works as hard as you do. When you’re pushing through thick brush or pulling a loaded grain cart up a hill, your cooling system works overtime. This coolant expansion tank is the unsung hero that handles pressure changes and thermal expansion, keeping your radiator protected and your engine running at the right temperature.

What You’re Getting

Proper pressure relief and coolant expansion management for high-demand operations
Durable construction that withstands the vibration and thermal cycling of heavy field work
Direct replacement design that fits your tractor’s cooling system perfectly
Clear sight lines for easy coolant level monitoring during pre-shift checks

Built for Real Farm Work

These big John Deere 8030 and 8R series tractors are the backbone of serious farming operations—pulling wide planters, running heavy tillage tools, and powering through tough harvest conditions. Whether you’re running an 8330 in the corn belt or pushing an 8345R through sticky soils, this expansion tank helps your cooling system handle the heat generated by engines that deliver maximum power when you need it most.

Made to Last

Farm equipment takes a beating, and radiators get the worst of it – vibration, debris impact, temperature extremes, and chemical exposure. This tank is built to the same standards as your original equipment, using materials that resist cracking and degradation from coolant chemicals and temperature swings that can range from sub-zero starts to summer heat.

Installation Notes

Installation is straightforward—drain the cooling system, disconnect the hoses, and swap tanks. Use proper coolant mixture, not straight water, and bleed air pockets carefully. While you’ve got the system open, it’s a good time to check hose condition and replace any that show wear or softening.
