Coolant Expansion Reservoir Bottle for Case Maxxum MX Series Tractors SKU: QT400222

A cracked or leaking expansion tank leads to coolant loss, air infiltration, and the eventual overheating that destroys engines. This replacement reservoir bottle maintains proper coolant levels and system pressure throughout the temperature cycles your Maxxum or MX series experiences during demanding field operations.

Why This Part Matters

• Designed to handle coolant expansion and contraction during temperature cycles
• Maintains system pressure for efficient heat transfer and prevents overheating
• Exact-fit design ensures proper mounting and connection to cooling system
• Prevents air pockets that cause hot spots and cooling system failures

Don't wait for complete failure—replacing a worn expansion tank now prevents costly engine damage down the road. Your Maxxum or MX series is built to be the backbone of your operation, and proper cooling keeps it running reliably season after season.
