Default Quick Question re: heater core

B6 A4 3.0

The coolant hoses into the firewall - and then heater core - are one on top of the other. Which one is into the heater core and which is the return?

Thanks!

Pray the heater core doesn’t go out! Jk, kinda. Had a B5 a long time ago and rode that through winters with no heat for years, head Nox Vidmate VLC out the window cause no defrost broke and young
