The owner of this R53 Mini cooper attempted to find the coolant leak on his car after having to repeatedly top-off the coolant and replacing the thermostat and gasket. We’ve identified the leak to be coming from the water pump weep hole.
This W11 engine is equipped with a supercharger where the water pump is mounted onto, a tedious location to get to. We’ve dismantled the front nose of the car to gain access to the water pump.
After the water pump is installed, we’ll be flushing out the wrong coolant the customer has been adding with BMW anti-corrosive coolant, formulated to properly protect the engine internals of a MINI Cooper.
This MINI is fully reassembled and ready to hit the road.
