Hi Bill –
My car is leaking coolant from under the car from a spongy looking box.
I am quite sure it is not a frost plug. Is it likely the heater core? Thanks Bill. Any info would help.
Hi Paul –
Take a clear picture of the leaking area and send it to us. If you cannot take a picture, take the car to someone ( your mechanic or a radiator shop ) who can pinpoint the leak for you. We can then possibly determine what is leaking and arrange to send you the necessary repair part or parts. We cannot see the leak from here of course, therefore my opinion without more information would be flawed and worthless.
