Only reason would be that the heater core is leaking.
Soundsw like heater core is going bad. You will smell antifreeze prior to actually noticing water/steam leak
Your intake is probably cracked. I had the same problem as well as others on a 98 LeSabre. I could smell the antifreeze and the fluid leaked down.
The "antifreeze smell out the AC vents" would mean only one thing, you have a small leak in the heater core.
Antifreeze has to be put in at the overflow bottle.
How can you smell gas when I start MY 97 jimmy - most strange!.
Regular antifreeze
dexcool is the proper coolant

Dexcool is recommended.
Blown head gasket.
would a cracked blocked cause a car to bubble antifreeze inside the reservoir of a 97 ford taurus ?
