Low coolant

Same fleetwood as the one with the yanking at 80+mph. I'm losing coolant from my resevoir visibly, but the mechanics at the shop told me it was the heater core but there is no water in or on the carpet inside. How can I tell if the heater core is really leaking? I've only had the car a year and I've changed the t-stat and gasket last summer. The low coolant light is on now but as soon as I fill it with anti freeze it will go off but when I drive it for a while and then park it, let it sit overnite. When I come back to it in the morning all of the coolant is on the ground. Yes there is a leak but I really dont know where. PLEEEEASE HEELP AGAIN

Sometiomes they leak only cold or only hot.

There are a couple ways to go after it.
One is to put dye in it to see where the leak looks like it is coming from. You may already be able to narrow it down by looking for dried coolant stains.

You may have to periodically check it as it cools to narrow it down. There may be things needed to move to see it.

You can also pressure test the sytem and search for your leak.

And yet still ask the guys where they see it.
