just did my intake manifold gaskets over reinstalled everything but forgot what heater hose goes from where the one from the water pump and the other from the manifold to which insert in the firewall, can anyone give me a picture or diagram, also my belt is screeching so loud and my alternator isnt at 14 volts because of this.

 

I do not think it really matters all that much, but I believe the top hose at the firewall goes to the water pump and the lower hose (closer to the passenger side) goes to the intake manifold.

 

The hoses and the fittings on the heater core are different sizes, 5/8" & 3/4".
