Hello there:
This leakage that youare seeing is coming from the heater core which means that you will need to remove the heater core and get a new one
The best way to do this is to Mark and disconnect the 2 hoses that are going thru the firewall to whick pipe they attach to on the heater core then remove the 6 or 8 nuts or bolts that hold it into place then you will find that the box that the heater core is sitting in may have some nuts and bolts on it to so remove them next the box itself needs to be seperated at the seam to assist in the removal of the heater core so cut along the seam with a very sharp knife or a utility knife and then remove the old heater core and install the new one then put everything back and dont forget to reseal the box otherwise you wont get much heat flow from the core de to air getting inside of the box ok then make sure you put sealant on the bolts where they go thru the fire wall and tighten it down firmly then reattach the hoses and you are done
Hope this is very helpful for you
Best regards Michael
You need to replace the heater core which is located behind the glove box under the dash
