BDFHYK 603-331 Mini Cooper Coolant Reservoir Quick Answer
If your Mini Cooper coolant reservoir is cracked, leaking, yellowed, brittle, overflowing, or no longer holding coolant properly, this BDFHYK OE-style aftermarket coolant reservoir is a replacement option for selected Mini Cooper 2002-2008 1.6L L4 applications. Before ordering, compare 17137529273, 17107515499, 603-331, EPT0016, and FRT1103C with your original part, then check the tank shape, hose port layout, mounting points, cap area, and any sensor connection on your original reservoir.
BDFHYK 17137529273 Mini Cooper Coolant Reservoir Overview
This BDFHYK coolant reservoir is used in the engine cooling system as the expansion reservoir and overflow tank for selected Mini Cooper vehicles. When the original reservoir is damaged, coolant may escape around the tank body, seam, hose connection, or cap area. Replacing the confirmed faulty coolant reservoir can restore a proper reservoir body for the cooling system, but diagnosis should confirm that the reservoir is the actual repair target before parts are replaced.

Mini Cooper Coolant Reservoir Leak and Failure Symptoms
From a buyer perspective, this part matters when the original Mini Cooper coolant reservoir is the confirmed source of coolant loss or visible damage. The symptoms below may point toward the reservoir, but they can also involve other cooling system parts.
| User Symptom | What This Product May Help With | Other Parts to Check |
|---|---|---|
| Coolant spots near the reservoir | May help when the coolant reservoir body, seam, or hose connection is leaking. | Hoses, clamps, radiator cap, reservoir cap, thermostat housing |
| Cracked, yellowed, or brittle tank | May be the right replacement if the original reservoir is visibly aged, split, or damaged. | Mounting tabs, hose nipples, cap area, nearby hose routing |
| Coolant reservoir empty after driving | May help if the reservoir cannot hold coolant, but an empty tank can also come from other leaks. | Radiator, water pump, hoses, thermostat housing, trapped air |
| Mini Cooper coolant reservoir bubbling | The reservoir should be inspected, but bubbling may also point to trapped air, pressure, overheating, or cap issues. | Radiator cap, reservoir cap, thermostat, cooling fan, water pump |
| Coolant smell near the engine bay | May help if coolant residue is found around the coolant reservoir or its hose connections. | Hoses, clamps, radiator, heater lines, nearby seals |
| Coolant overflow or repeated level drop | May help when the tank is cracked or leaking, but pressure and airflow issues should also be diagnosed. | Cap condition, trapped air, thermostat, radiator, fan operation |
Who This 603-331 Mini Cooper Coolant Reservoir Is For
- Mini Cooper owners who found a cracked, leaking, brittle, or stained original coolant reservoir during inspection.

Where the 17107515499 Mini Cooper Coolant Reservoir Is Used
The coolant reservoir is part of the vehicle cooling system. As coolant expands when the engine heats up, the reservoir provides a controlled area for overflow and recovery. When the engine cools, coolant can return as the system requires. On the listed Mini Cooper applications, the replacement coolant reservoir should match the original tank shape and connection layout before installation.

Mini Cooper Coolant Reservoir Installation Notes
- Let the engine cool completely before working around the radiator, hoses, or coolant reservoir.
- Do not remove a hot radiator cap or coolant reservoir cap if the cooling system may be pressurized.
- Compare the original coolant reservoir with this replacement before installation, including OE number, tank shape, hose ports, mounting points, cap area, and sensor connection if present.
- Drain or recover coolant as required by the vehicle service procedure and local handling rules.
- Use the coolant type and mixture specified for the vehicle.
- After installation, refill the cooling system and bleed trapped air where the Mini service procedure requires it.
- Inspect hoses, clamps, radiator cap, reservoir cap, radiator, thermostat, cooling fan operation, and water pump area during the repair.
- If the old reservoir failed because of pressure or overheating, diagnose the root cause before installing the new coolant reservoir.
- If the leak source is uncertain, a cooling system pressure test can help confirm whether the reservoir is the correct repair target.
