    I have antifreeze leaking under the car on the passenger side. There is no antifreeze in the floor board of the car. I looked at the connections to the heater core and they look fine. Then I look lower toward the floor and see another connection at the firewall that has no pipe going to it and appears that this is where the leak is coming from. Is there suppose to be a plug in this hole?

    The 1st thing that I would suggest, is to check the hose clamps for hardness and visually look for any symptoms (stains from coolant) etc. It is also possible that you got a faulty pump.

    Are you losing coolant? The "pipe" you see exiting the firewall is probably the condensate drain and it you have a bad heater core the leaking coolant can sometimes exit here, depending on how the system is designed. Have you verified visually (I use a clean paper towel) and smell that it's coolant?
