Coolant leak under dash

Good morning.

If it is coolant, it is leaking from a failed heater core. It is the only component inside the car that carries coolant. It must be replaced to resolve the issue.

Are you going to attempt it yourself?

Okay, I will get some directions for you for this.

I do not know about any free manuals but parts stores have manuals for this.
