Frank Carbone Posted January 19, 2005 Report Share Posted January 19, 2005 Hello All I have a 92 Seville with a 4.9L engine and have noticed that I dont get hot air much from the heating system. The car runs at 175F all the time but the air comming from the heater is just luke warm. I have changed all the coolant recently and the thermostat was replaced last winter. I also replaced the rad cap when I replaced the coolant. Also every once in a while I can smell collant in the cabin but the widows don't fog up and the coolant level seems to be fine. It's not always either. What is the normal operating temp for this model Caddy? Link to comment Share on other sites More sharing options...
