MINI Clubman F54 Coolant Expansion Tank Malaysia
The plastic coolant expansion tank on the F54 is a shared design concern across F-generation MINIs. For the Clubman, which often accumulates higher mileage as a practical everyday car, the expansion tank is worth replacing proactively at the 4-year coolant change. Hairline cracks cause low-level coolant loss that can go unnoticed until it becomes a more serious overheating event.
