I usually don't drive on the highway, but I had to pick up relatives from the airport. One the first trip to the airport everything seemed fine, then when I was heading to the airport again the Temperature Gauge was lower than normal. It freaked me out because it was so low, and I noticed the engine smells more, possibly because the engine is not at the correct operating temperature. What could the problems possibly be? I'm thinking the thermostat maybe not be operating correctly, going to take it into Auto Tech tomorrow and see what my teacher says. Any help is appreciated.
