On the 2007-2016 MINI Cooper, both R56 and early F56 Coopers use an electric thermostat housing and electric water pump that are prone to premature failure. The thermostat housing cracks causing coolant leaks, and the water pump impeller can fail leading to overheating.

This issue also affects: MINI GP, MINI Roadster, BMW M3

Common Symptoms

  • Coolant warning light
  • Overheating
  • Coolant puddle under car
  • Heater blowing cold air
  • Temperature gauge fluctuation

How to Fix

Replace thermostat housing assembly and/or electric water pump. Use updated MINI parts. The thermostat housing is on the front of the engine and relatively accessible. Water pump is belt-driven on N12/N16, electric on newer B38/B48.
