Answer
Hi Raewyn

Typically when there is coolant coming out inside the car, especially passenger side, it is the heater core. If you use the heater in the vehicle, you should replace it. Part of the duct work system will have to be removed to get to the core. It looks like a small radiator within the system.

The other option is to remove the heater hoses, and replace with heater plugs. This will disable the heater core, and coolant will no longer go through it. This is a inexpensive option, but remember you will not get heating capacity in your cab.

Hope this helps -
