I was just wondering. Since I put my new Napa Heater Core in I have not ever though: "wow, that sucker is getting hot!" My temp gauge- yes gauge- I installed one on the passenger side boss, rarely tops 130* for the first 30 minutes or so. Today I got it near 150*. Beats overheating, I know, but I could use warmer air. What is the proper range I should see in the winter?
