Need heater core hose help
1994, club wagon, 5.8
Years ago the previous owner had a shop bypass the front heater core in the engine compartment. Theres also a rear heater core. I bypassed that one myself at the core.
There are two hoses not connected to anything hanging in the engine compartement that are coming off two hard line tees at quick disconncts. The old heater core is still there.
Does anybody have a diagram or know where these hoses are supposed to go?
I have searched to no avail.
It looks like one might go to a line coming off the pump because there is a hose looped back and connected to a hard line with a hose clamp.
Thanks.

At the engine, you should have one off the pump, and one off the intake near the T-stat, like so:

Looks like the one off the manifold is the "supply" hose, going into the lower heater tube.
Your hard lines should just be replacing longer rubber hoses, and should end near the heater cores with the final connection made with rubber hoses.
Do your hard lines look like this?

Maybe a little different since theres a rear heater core as well.
I am pretty sure I traced the lines coming from the core to the hard lines but cannot figure where these loose hoses go.
Next chance I get I will see if there is a hose coming off the intake. I see one coming from the pump.
