It's almost always the water pump/thermostat housing - there is a v. thin gasket between them and at least on mine, that's where it was leaking from. Can see it if you use a mirror.Found a small coolant leak under my car. It’s coming from the front of the engine and dripping down in the area of of the oil level sensor on the sump.
This is a new development and doesn’t appear to be connected to my Auxiliary radiator install (Sept 2020), although I plan re-checking everything I touched.
I’m assuming water pump weep hole but, but not sure whether the MK7 water pump as a weep hole when the seal fails.
What are the most common failure point? Water pump or thermostat housing?
Are the quick disconnect hose couplings a problem?
