got the same issue with fx45 2004. Could not figure out what is causing this.
The average length of desktop in centimeter is 14 cm. It comes in different lengths.
While your car is running the engine is heating up. While your driving you have air being forced over the radiator cooling it off. When you are sitting still you don't have that air so your engine is heating up even more so the cooling fan comes on to help cool you engine off. Via cooling the radiator.
One is for oil pressure. The other is for the alternator. And if THAT light comes on, for God's sake get to the side of the road and shut the engine off NOW!!! The cooling fan for your engine is bolted to the end of the alternator shaft, and the most common reason that light comes on is that your fan belt broke. No belt = no cooling = no engine.
When 1990 Honda is running cooling fan does not come on but comes on when engine is off and I thermostat and temperature switch changed?"
The cooling fan comes on when the engine reaches a certain temperature and is controlled by a sensor switch that kicks the fan on when the temperature reaches the preset temp.
the engine temperature has to get to 225 degrees Fahrenheit to turn on. If the engine is reaching 230 degrees and it is not turning on the sensor for the engine cooling fan is most likely the culprit. As for the fan operation of the fan with the a/c that is normal
If your engine light comes on and your temp gauge is lower then normal. listen for cooling fans. if they are also running chances are you need a new thermostat
the cooling fan comes on at 230 and normal engine temperature is usually around 218 depending on the outside temp.
The cooling hose flange is usually not equipped with a plug. That would defeat the purpose of having a cooling hose. If the flange pulls out of the radiator, you will loose all the coolant and you should shut down the engine so it won't burn up.
Whenever the AC is turned on, both cooling fans also come on. Otherwise, during normal operation only one fan comes on when activated to maintain correct engine temp.
It is heated to such a high temperature by going over the engine which is really hot and is part of the cooling system, the cold air goes over some part of the engine and comes out hot. It is part of the cooling system of a car, so therefor if your car has overheating problems turn the heater on.
The engine cooling fan is not suppose to stay on. The temperature sensor on the motor tells the fan to kick on if the motor ever gets too hot, usually comes on at 210-215 if I remember right.
