I have a 1994 GMC Jimmy, 4.3L V-6 Vortec Engine. Inside the vehicle you can smell Anti-freeze when the heat is on and the Water Temperature Gauge does not move much at all. It has good heat, but the smell is getting worse. I believe it is the heater core. I am not a mechanic, so how much does this normally cost to have this replaced?
