You’ll have to excuse me but I have no idea what you’re talking about
Ok, you mean to drain the radiator ?? No, it’s coming from this piece that looks like a little pump. The “connector” that looks like it made to receive a hose is leaking. Sorry about the sideways pictures. You can see a drip starting, that’s where it’s coming from
I’ve put that pink summer windshield washer. It’s very well possible. I guess my coolant reservoir happened to be empty at the same time which is odd. Is there supposed to be a hose there ??
