The coolant smells and tastes sweet and I wish they do something about that. Rats, mice, and other critters are attracted to that and will chew some harnesses once they get in there. I would highly recommend extracting the coolant first and cleaning up the remaining that will still drip with some cleaner.
Good video, how did you know it was the sensor fitting that was leaking? Mine just started leaking the amount in the reservoir and I refill it and it leaks out again.
This one wasn’t actually leaking, it was just showing that the level was low even though the coolant stayed perfectly on the maximum line. I’d recommend a coolant system pressure check to try to identify where your coolant is escaping, there will be another video (coming tomorrow) showing how to perform the coolant pressure test.
