Hi all. Have a 99 Grand Prix. The heater core was bypassed by the previous owner. Obviously a leak or something. I ordered a new one. I was looking where it was bypassed and teh connectors for the old core, I am not sure which hose would go where. Which one is the intake and exit? I've attached we links to my flicker page showing the bypassed hose and teh connectors for the heater core. I couldn't get the photos to embed in my post. Sorry.
