Q: Car temp reading hot but not overheating

Hi Jennifer. One of the most common causes of an engine that runs hotter than normal is due to air bubbles in the cooling system. If repairs were made to the radiator and the replacement coolant was not correctly bled as recommended by Nissan, this tends to occur. However, there are other possible issues, ranging from an obstruction inside the heater core or the coolant being too thin (meaning more water than coolant). It’s supposed to be a 50/50 ratio of coolant to distilled water. To ensure you have the right repairs completed to resolve this problem, it is best to have a professional mobile mechanic come to your location and complete a car is running hotter than normal inspection.
