ok before i go ripping out the dash to change the heater core i have a couple ?'s
if the heater core was bad there would be coolant in side the car right well mine is leaking out of the grommet on the firewall and down onto the underside of the car any suggestions

 

Check the hose and fitting first. Removing a heater core really sucks.

 

i think that the fitting for the haeter core are connected together
