BDFHYK Engine Coolant Expansion Reservoir Overflow Tank Replacement
This BDFHYK engine coolant expansion reservoir overflow tank is designed as an OE-style replacement for selected Ford Super Duty and Excursion applications. It is intended for drivers replacing an aging, cracked, stained, or leaking coolant reservoir and who need to confirm fitment before ordering.
A coolant reservoir helps provide a visible coolant level reference and supports normal coolant expansion and recovery within the vehicle cooling system. If the original reservoir is brittle, difficult to read, or showing coolant seepage around the tank body or hose connection points, replacing it with the correct reservoir can help restore the cooling system layout to its intended configuration.
Vehicle Fitment Reminder
Please confirm your vehicle year, make, model, engine, and OE reference number before ordering. This coolant reservoir is designed for selected applications including Ford 2003-2007 F-250 Super Duty, 2003-2007 F-350 Super Duty, 2003-2007 F-450 Super Duty, 2003-2007 F-550 Super Duty, and 2003-2005 Excursion 6.0L V8.
Fitment may vary by trim, engine configuration, production year, and cooling system layout. Always compare your original reservoir shape, mounting points, hose connection locations, and OE number before installation.
OE / Interchange Reference
- 603-217
- 3C3Z8A080AE
- 6C3Z8A080B
OE numbers are provided for fitment comparison only. Please verify that one of these numbers matches your original part or your vehicle parts catalog before ordering.
Common Replacement Signs
- Visible cracks, yellowing, or brittle plastic on the original reservoir
- Coolant stains or wet areas around the tank body
- Repeated low coolant level after topping off
- Sweet coolant smell after driving
- Coolant puddles under the vehicle after parking
- Hard-to-read coolant level marks on the old reservoir
These symptoms can also be related to other cooling system components such as hoses, clamps, radiator cap, thermostat, radiator, or water pump. If coolant loss continues after replacement, inspect the full cooling system.

FAQ
How do I know if this coolant reservoir fits my Ford Super Duty?
Confirm your year, model, engine, old reservoir shape, mounting points, hose connections, and OE number. Do not rely on the model name alone.
Can a leaking coolant reservoir cause low coolant?
Yes. A cracked or leaking reservoir can allow coolant loss. Low coolant may also come from hoses, radiator, water pump, thermostat housing, or other cooling system parts.
Does this coolant reservoir fix overheating?
This part replaces the coolant reservoir. Overheating can have multiple causes, so inspect the full cooling system if the issue continues.
Should I replace a yellow or brittle coolant reservoir?
Aged or discolored plastic may indicate heat-cycle wear. If the reservoir is brittle, cracked, leaking, or difficult to read, replacement may be needed.
