    Help !!! Coolant Leak 1994 Deville

    Hi, my car is 1994 Deville 4.9L
    Yesterday while driving i've noticed smoke or vapors coming out from the passenger side of the defroster duct, there was also a smell but not like an electrical burning smell.
    I checked the car today and i saw coolant fluid leaking into the car at the foot area of the passenger seat, i moved the carpet and discover a severe wet all over.
    I think it is the small heater radiator, I need to know if i can disconnect the heater outlet hose and the heater inlet hose and connect them directly so i bypass the heater ?
    If i do so , i understand it will affect with no heater, but will it affect the A/C low temperature ?
    Can i change only part of the heater module, i have the service manual and didn't find any reference about this heater.
    What are my other choices ?
    bye

    I think that what you're planning to do will work.

    Sounds like your heater core is shot. This is a very involved repair for most cars. It happened to my wife's Volvo a couple of months ago. Anti-freeze all over the floor of the car. Good luck.
