I have a leak running down the firewall on the passenger side of the vehicle. It is in the location of where the heater hoses go through the firewall. I do not see any leaks at the hoses.
Do you
have the same problem?

Good evening.

It sounds like your heater core is leaking.

I attached a picture of it for you to view.

Will you be doing this procedure yourself?
