What does a cooling fan do for your car?
Basically, a radiator fan blows cooler air through the radiator to lower the coolant temperature and cool off the heat from the car engine. Obviously, when the engine is running, it produces heat. That heat must be dispersed so that the engine will not experience any form of overheating or become too hot.
Why is the radiator fan not working on my Nissan Altima?
Without the coolant hitting the sensor, the temp reading will be significantly lower than the actual engine temp. Your Altima’s radiator fan will not kick on. If you do have low coolant, don’t fill it up until the engine has cooled off.
Why are the cooling fans always on in my car?
One thing is for the cooling fans to come on when the engine is hot and another is for it to be stuck on when the engine is first started. When the cooling fans are stuck always running then typically it means that the ECU is not detecting the engine coolant temperature (ECT) sensor or something thereabouts.
What to do if your Altima has a bad temp sensor?
If your Altima has a bad engine temp sensor the radiator fan won’t know to come on, because the ECU won’t know how hot the engine is. You’ll need to locate and test the engine temp sensor. Depending on the model year and engine, the location varies. If it does end up being this sensor, they are very affordable.
Why is my radiator fan not working on my Toyota Camry?
If you do have low coolant, don’t fill it up until the engine has cooled off. Adding coolant to a radiator dry enough not to trigger the engine temp sensor can cause problems from drastic temperature change. Let it cool down first. Like any other clutch, a fan clutch will wear out over time.

When does the fan always on Nissan club?
Click to expand… no only when the car starts. Also before they install the new T-Stat they hook up their reading and it says coolant low and after they install the T-Stat the coolant reading says high and they flush out the coolant and mix the coolant 50/50 and it still says high. Low & Fast…
