Tricky Coolant Leak
New to the forum and it's my first Benz. I'm having trouble finding an intermittent coolant leak on the passenger side thermostat / auxiliary water pump area. It will leak out half a reservoir container when I'm not looking, won't drip a drop when I'm searching for it. I see drips on the alternator, area around the auxiliary water pump and thermostat housing. Not a lot, like it's really leaking, but just little droplets. One time I saw some coolant drips on the bottom of the bottom radiator hose.
I've heard the short 2" rubber hose at the thermostat is a usual suspect, but as I recall it only seemed to have droplets in that area when I checked.
Any help would be appreciated. Thanks.
