In December I posted a typlical cooling system problem that I have been having with my 98 Sable. Basically no heat do to a clogged system. I had the system flushed including the heater core and my heat came back. The problem now is that I smell antifreeze inside the car when the heat is on. I realize that there is most likely a leak in the heater core. It must be a small leak though because there are no other signs of a leak. I used Bars Leak and it seemed to get better for a short time but now the problem is back.
Beyond replacing the heater core is there anything else that might work to help fix this problem? Is there a better stop leak product that might work? Thanks for your help.
