Why is the heat not working in my Nissan Altima?
The most common reasons a Nissan Altima heater isn’t working are a broken heater blower motor, a problem with the thermostat, or a failed heater blower motor resistor.
What kind of antifreeze does a 2003 Nissan Altima take?
Prestone 50/50 Coolant/Antifreeze.
Why does my Nissan Altima overheat?
While there are a variety of reasons your Nissan Altima is overheating, the most common 3 are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
Why do some cars have 2 thermostats?
Their purpose is more for aerodynamics than engine cooling. The dual thermostat system was designed to accomplish the same temperature control under different load conditions. Instead of manipulation of the air side of the radiator, the coolant flow to the radiator is varied.
Why is my car blowing out cold air when the heat is on?
There are a few basic issues that usually lead to the blowing of cool air from one’s car heating system: There isn’t enough coolant in the engine. There is a problem with your heater core. Your thermostats are not working correctly.

What is blue coolant?
A blue engine coolant temperature light only indicates one thing: that your coolant, or antifreeze, is too cold. In fact, the temperature is so low that it is possible for your radiator to get too cold, thus resulting in your engine freezing up and not being able to start.
How do you know if your car thermostat is working?
Start your car’s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
Why does the lb7 have 2 thermostats?
Their purpose is more for aerodynamics than engine cooling. The dual thermostat system was designed to accomplish the same temperature control under different load conditions. It may be necessary to block the air side of the radiator to allow the liquid temperature to get high enough to evoke full coolant flow.
