Adding k seal
Heater core has a leak. I went and bought k seal
but I don't know where to add it to. It says radiator
but I can't find my radiator on my pontiac g6 2007
You add it to the coolant reservoir, but personally, if you are going to keep the car, I would replace the heater core.
Agree with TOM. I wouldn't put that crap in my car. Get the heater core fixed.
