Stupid question. I searched to no avail. When replacing the heater core hose, how does it go? Two side ways in the firewall, two vertical under the intake upper. If facing the windshield, is it left to top, or left to bottom? Does it matter? Thanks all! Oh, does anyone have a diagram of how the A/C lines run as well? Again, THANKS!
