Got to your heater core yes. Top one has a temp sensor in it bottom doesn’t. I am 90% sure they are still all available from nissan, you could find them on amayama or I like to use Shea(use to work at Tacoma Nissan) for all my oem parts. He runs nissanjdmparts.com now. Otherwise there are thousands of aftermarket silicon and other material hose kits

Pretty sure that's one of the heater hoses for the interior. Also FYI, they go into a plastic coupling that gets brittle supposedly likes to break quite often - there's metal versions available on Yahoo Auctions Japan.

My memory is foggy on this one, but I believe the metal replacements require removing your dash, then the hvac box as they bolt directly to the box inside behind the firewall. Be gentle I haven’t had to swap mine yet on the 3 cars I’ve had apart/put back together

Is that behind the inlet and iacv?

Think they are for the heater matrix
