Sounds like you may have a leaking heater core. A pressure test on the cooling system can determine if there is a leak in the system

ya i am leaning towards heater core but i have put about 75 miles on it and fluid levels are staying the same and no wet spot on carpet and is it true i have to remove dash to replace heater core?

well its in the shop they pressured it up last night and in morning its still the same no leaks so now there thinking maybe a plugged rad maybe so they are going to drain the system ,
