Here I am again guys. I am trying to do a heater core flush with a kit i bought however need someone to direct me to they correct Codie because I absolutely cannot identify them and I have watched five different videos and they are no help. I understand that they go into the Dash at some point into the heater core however I cannot find them and really don’t know what I’m looking for other than two black hoses. So if someone could please tell me exactly where these two hoses are I would appreciate it so much and also if someone could tell me which one of those I am supposed to flush the water through. I know my questions sound stupid to you guys but I really need help and will be grateful forever

 

there are 2 black hoses approx 1' round going into the firewall. the have clamps on the end of the hose to remove to have access to the heater core. location is abou0t the center of the firewall below level of the radio. there are no other hoses that go into the firewall. (firewall- metal plate to prevent fire from entering the passenger cabin in the event of an engine fire.)
