What keeps the radiator fan from running all the time once the engine gets hot on 1999 Nissan maxima?
Possibly a faulty coolant temperature sensor. It could also be a bad fan relay, bad ground at the computer, or faulty wiring of the coolant fan circuit. How about a bad water pump. I don't think in this instance the water pump would be the issue. The radiator fan is designed to cycle on and off depending on the temperature of the coolant circulating in the engine. The water pump is what is responsible for that circulation; from the engine, to the radiator and back again. If the water pump was not functioning properly, the coolant would not be able to circulate from the engine to the radiator, and the engine would overheat. If this were the case, the temperature sensor in the block would signal the computer to run the radiator fan continuously in order to cool the engine. The question being asked is why does the radiator fan turn off, even when the engine is hot? Not why does my radiator fan never turn off?
Why would the fan come on immediately after start up then go on and off occasionally?
Your electric engine cooling fan is controlled by one or more sensors in the cooling system, which turn the fan on and off depending on engine temperature. If a sensor is going bad the fan may run at any time.
Why does the radiator fan on my 2005 Chrysler t and c run all the time?
Either your engine is running hot or the fan switch in the radiator has failed or the relay is stuck.
