During the process of changing the heater core I found out that the heater valve is missing (my car has AC). So I ordered the correct hoses for a 69 CJ with ac. I have two questions:

1 - One of the heater hoses is molded with a 90 degree angle on one end. Does this end of the hose connect to the water pump, the intake manifold or the heater core?

2 - I know the heater valve goes on the inlet side of the heater core, but which side is the inlet side of the heater core - the passenger side or the driver side?

Question #1 is to the heater core. It goes from the Heater Valve to the Core it self (Pass. one).
This answers Question #2

the heater hose with the single 90 degree bend goes to the outside (rightmost) heater core connection and runs to the waterpump.

there is supposed to be a short hose with 2 90 degree bends that goes from the inboard heater core connection to the water valve. the other end of which goes to the intake. Off hand I don't know for sure which direction the watervalve is supposed to point. I think ther arrow points towards the firewall.
