Which heater core hose is the inlet and which is the outlet? I'm afraid mine might be hooked incorrectly.
Could someone look at their grand prix and see which hoses go where? Would be really appreciated.
Heres a diagram to show how my hoses are connected.
The pink is connected to the top hole in the firewall.
The blue is connected to the bottom hole in the firewall.
Is this correct? Which of these are intake and which is the outlet?
