I'm wondering which is the inlet and which is the outlet for the heater core connectors that come through the firewall. Passenger side is ??? And drivers side is ???

Thanks for the help. My computer crashed and I lost most of my tear down pics for my swap

 

couldn't tell you which is which specifically, but I do have this if it helps at all

 

Deesnt matter which one is in or outlet. It just need the hot water foe the heater but most of the time the inlet line is the one with the opening passage. If that makes Any sense. Hahahaha

 

Generally the heater valve in on the inlet line to the heater:

So the copper fitting coming out of the firewall that's on the 'drivers side' is the feed for the heater core then? Kinds tough to tell as I can't trace the hoses on the pics! Lol. Thanks for the input but please more help! I'm putting a 7mge in and need to figure out the hoses

 

so is my previous post correct? the drivers side is 'to heater' and the passenger side is 'from heater' ????? thanks for the help!

 

Ttt. Anyone? From the replys and pics it looks like the drivers side one is the heater feed. am I able to 'reverse' them? ie. Head-hose-valve-hose-enter passenger side-exit drivers side-hose-connect to steel return line would this work or do I HAVE to have the hot water from the back of the head enter on the drivers side? It would be easier if I could switch it but I need to know what's what first!!! Thanks again!!!!

 

It doesn't matter which one goes where.

 

Awesome. So as long as water goes in one end and comes out the other, everything is good? Lol. If that's the case, I'm set! Now I won't have a whole medd of hoses going from one side to the other and back. Thanks for the reply

 

You got it!

 

Sweet man, thanks again!

 

On my 87 the inlet is on the driver's side and outlet is on the passenger's.
