I just bought a 1999 ford taurus 6 cylinder 3.0, I am not sure how to tell if I have the duratec or vulcan engine? I found out it has no heat. When I stop and the heater is on I smell a little antifreeze no fog on windows. Black sluge in antifreeze reserve. The engine misses. I used to lose antifreeze I probably put in a gallon and a half in the first month I had the car. For the last week and a half I have not lost any noticable amount of antifreeze
When I noticed i had no heat I took it to a radiator man to have it flushed. He checked the coolent system with and sniffer and told me there is carbon monoxide in the system and that it has to have a cracked head or a blown head gasket.
The car has 150 thousand miles on it and I just bought it for 2 grand. It is very nice except for the problems.
oil and transmission fluid are good and there is no antifreeze in them. No noticable white smoke out the muffler.
can anyone help please thank you
