Small drips are running from both driver and passenger side. The leaks look to be coming from two black chamfered rubber pieces. Can anyone help identify those parts?
Update: I found the two pieces to be rubber and to be part of the cabin temp sensor module (

Part Number:5h2219874ab)[size=16px]. They open up very easily and so I can see the coolant dropping consistently. My question is - are they supposed to be dripping coolant like that by design, and if so what causes it? Should I replace the temp sensor module completely?[/size]

Coolant system only holds pressure to -10kPa inHg under vacuum, instead of -25.

Already replaced cross over pipes, water pump, pcv valve, thermostat housing.
