Coolant Leak on 2005 Chevy Impala

Unread post by Sanity » Sat Dec 12, 2009 7:25 pm

Our car leaks fluid. (2005 Chevy Impala) There is a puddle of antifreeze underneath, but when we go to add water or coolant, the radiator seems full and overflows if we add more. We can't seem to find where it is leaking from. Also the heater stops working and when we add a little antifreeze (as much as we can fit) it starts working again but only if we add the stuff we buy from Napa. If we buy it from a c-store or Walmart it doesnt make the heater work. Do you have an idea of what the problem is?
