I don't know what can be causing my 2006 Nissan Altima 2.5 to run hot.
I just changed out both thermostats and the car still runs hot. It would be fine
until driving a couple of miles. Then the gage would start to rise and I would
have to turn the heater on full blast to keep it from getting too hot. Once
stopped and parked, you can hear the coolant bubbling from being to hot.
