Use the oil furnace if your car is overheating

Our daughter was making the 6 hour drive from her home to ours.

  • She makes this drive at least once a year so all of us weren’t anxious.

However, she called about an hour from my home and said that her car was close to overheating. She explained that she had checked the fluids and they were wonderful but that the temperature gage had been straddling the red line for over an hour now. I told her to turn off the car’s a/c and to turn on the heater. That would help remove heat from the engine. But, if the gage went into the red, she needed to pull over and call me. I would come get her. It was a absolutely warm day so I cranked the a/c down in our home in preparation for her arrival. Sure enough, our daughter pulled into the driveway about an hour later. She was hot and uncomfortable but her car made it. She was absolutely grateful for the air conditioning in our house. After all, she had just driven an hour with the oil furnace blasting away in her car. The people I was with and I were all relieved that she was here safely. While she napped in the air conditioned home I took a look at her car. It turned out that there was nothing wrong with the cooling system at all. It was just a faulty heat sensor. So she didn’t need to run the oil furnace in the car at all. I didn’t tell her that though. I just fixed it for her. Now she can use her air conditioning when she drives back in a week or several.
