Hi anyone, just notice the mini R53 has coolant in green dripping by drops when parking unused for couple days at a mild slope at home. has anyone had this issue before? just replace a new coolant reservoir 2 weeks ago, from the engine bay, looks clean and no wet hoses at all. just the oil pan. Can anyone tell what might be the problem. thanks in advance.

do you have the blue MINI antifreeze or a green antifreeze. Location shows a possible thermostat housing leak. Normal to need replacing.

Almost defiantly water pump issue on a R53 as it’s located on the end of the supercharger.

Thermostat housing is common.

i am not sure if its blue or green as it can be both.. will take another picture tomorrow to confirm. can it also be the stuff from AC? color should look similar.

The ac fluid is bright green, mine sprayed everywhere when one of the hoses failed!
If it is green I’d check the ac is working and look for leaks on the pressurised ac lines
