I have a 2009 mini cooper with a small coolant leak near the right front passenger wheel. Any way to tell whether the leak is from the thermostat housing or the water pump? Thanks

 

Most likely the water pump, the water pump is on the right side ( passenger ) closest to the wheel . If its leaking on or near the transmission on the driver side its the thermostat.

Water pump sets in the back corner of the engine on the passenger side.




Here is what the water pump look like , look for leaks around it.

There is a pic of the engine without the water pump installed if that helps. There is a water pipe behind it also that seals into the housing. Check that also, could be leaking near the water pump side.





Water pipe.

Here is the MINI OEM coolant also once you find out the leak.
