Hello, I own a 1998 Altima (GXE). 160 000 km. For the last two days, the motor temperature guage needle indicates low motor temperature (1/4 between the C and the H). Yesterday I was in heavy traffic for more than an hour. I notice the needle being a bit lower than usual for the whole drive except that when traffic picked up and was driving at regular highway speed (70 km/hr), the needle got even closer to the C! Its quite cold in Montreal these days, however it is nothing new and never the car behave such a way. This morning, I notice again the temperature needle to be under its regular position. I notice that the heat coming out of the vents to warm up the inside of the car is not as warm like it usually is. Can you please help me? Thank u very much.
