Why is the radiator fan not working on my Chrysler 300?
Why is the radiator fan not working on my Chrysler 300?
If your 300 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.
What should I do about my Chrysler cooling fan?

Why does my car have a radiator fan?
You probably already know the purpose of the radiator and the cooling system in your car. When you are driving fast, the wind is passing through the radiator to cool the coolant down without issues, but when you are driving slow, there is no wind pushed through the radiator. This is why we use a radiator fan.
Where is the relay on a radiator fan?
The fan relay is often located in the engine bay’s fuse box, but the best way is to check your repair manual to find where it is located. Testing a 4 pin relay is often very straightforward. Remove the relay and give 12 volts to pin 30 and 85. Ground pin 86 and check if there is voltage coming out from pin 87.

What causes a Chrysler 300M engine to overheat?
Higher concentrations may result in poor cooling performance and premature water pump seal failure. This antifreeze/ coolant may not be mixed or substituted with any other type . When Engine is cold: Thermostat is closed, cooling system has no flow through the radiator.
What happens when you turn off the airconditioning on a Chrysler 300?
The engine temperature immediately begins to drop and then settles in at just below the half-way mark. This tells me the system is clean and that the coolant is flowing nicely. BUT, as soon as I turn “OFF” the airconditioning, the lower radiator hose begins to slowly cool down and the engine heats up again.
What does it mean if your radiator fan is not working?
Your Chrysler 300 ‘s radiator fan has one of the most important jobs on the vehicle. It is the last line of defense between you and an overheating engine. If the radiator fan is not working, it’s a serious problem. Just because the radiator fan is not on does not mean that it is not working. They are designed to only run when needed.

What kind of cooling system does a Chrysler 3.5L use?
The cooling system on the 3.5L uses a water pump with a molded plastic impeller. The design is more efficient than a typical stamped metal impeller and produces less cavitation, but the soft plastic impeller can be eroded and worn down by rust and sediment in the coolant.

Is the cooling fan relay on a Chrysler working?
The cooling fans on Chrysler cars are not particularly well-made, but that doesn’t mean you can assume that they are broken the second the cooling system stops working. Watch this video to figure out how to diagnose problems with the cooling fan relay on a Chrysler.
What happens when you fill up the radiator fan?
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.
1. Engine running hot One of the first symptoms commonly associated with a bad or failing cooling fan relay is an engine that runs hot or overheats. If you notice that your engine is running at higher temperatures than normal, that may be a sign that the relay is not functioning properly.

How does the cooling fan relay work on a car?
The cooling fan relay is the relay that controls the engine’s cooling fans. When the correct parameters are met, a temperature switch or the computer will activate the relay, which will allow power to the fans. The relay will usually be activated once it is detected that the vehicle’s temperature…
Is the cooling fan still running when the engine is off?
That is because it is measuring coolant temperature, not engine temperature. The engine is still much hotter than the coolant. Yes, the engine still puts out heat even when it is off. You want to remove excess heat.
Why is my computer cooling fan not working?
A stuck closed relay is the only thing that can operate the cooling fan continuously with the key off. The computer looses power with the key off and the same applies to the coolant temperature sensor. The relay, however, has direct power to one side, the same as a light switch.

What should the coolant temperature be on a GM 3.8L V6?
As the engine runs, the coolant temperature (your scan tool is reporting) will reach 225° F (107° C). When it does reach this is the temperature, at least one of the two radiator fan motors should start (if equipped with two).
When to turn off the fans on a GM 3.8L V6?
When the coolant’s temperature reaches 227° F, the fan or fans come on. The fans will bring down the temperature of the coolant (inside the radiator) which is circulating to the engine (due to the open thermostat). Once the temperature decreases down to around 200° F, the PCM then turns off the fan or fans.
