My 89 Sundance is loosing coolant. I think it's coming from the bottom of the motor, or the back of the motor between the firewall, but I am not certain. I have a 2.5 gas. Do these have freeze plugs? Any suggestions or help would be appreciated. Could it be a head gasket? if it were, would the car still run ok? I can drive it around like there is no problem at all, except for the fact that the temperature is rising pretty quickly.
