Got my car back today from the shop. Driving on the freeway it stays about halfway between 80 and 100. Sitting at a stop for a while, it climbs to about 3 mm above the 100 degree mark and stays there (in 75 degree weather today). Definitely running hotter on the gauge than my last engine. Not sure why. Same radiator, different water pump and different water temp sensor??? Is this a good thing?
