Q: 93 buick century 6 cylinder. Overheating. Thermstat, and fluid serivice done.

asked by on April 21, 2017

Takes about 20 mins of driving for heater to start blowing warm (not even hot) air. About 30 mins and the engine starts smoking from underneath. Recently had the thermostat changed out, and full coolant service done at jiffy lube. The issue preceded that service. Just hoping that would fix it. It did not.

My car has 90000 miles.
My car has an automatic transmission.
