My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
A broken wire can generally fixed, but if the break is too close to the connector, you may want to replace the connector itself. If there is any corrosion inside the connector, then definitely replace the entire connector and the component it connects to for the best result. Consider having an experienced technician, such as one from YourMechanic, come out and take a closer look to offer a more personal diagnosis on the radiator fan.

A 3-wire fan has power, ground, and a tachometric (“tach”) output, which provides a signal with frequency proportional to speed.
In most cases, a properly maintained radiator fan will last between eight and ten years. When the radiator fan fails, it should be replaced as soon as possible. This is because without a cooling fan to help remove heat from the engine, your car is more likely to overheat and cause damage to important engine components.
Engine overheating: A bad radiator fan can cause the engine to overheat, especially at low speeds. If your car starts overheating, pull off the road as quickly as you safely can and turn off the engine. An overheated engine can quickly get ruined and lead to expensive repair bills.
A 3-pin case fan can easily be connected to a 4-pin connector on the motherboard. The fourth pin is simply left blank in this configuration. In most cases, it will then run unregulated at a fixed speed. Some newer boards offer the possibility to adjust the fan speed by voltage.
Wiring a ceiling fan with four wires is the most common. However, an additional color wire might be included.
The three parts that commonly cease working after the radiator goes bad are the thermostat, water pump, and heater core.
Yes, you can drive your car without a radiator fan in your car, but you never should. Every time your engine overheats, damage is done to your vehicle`s cooling system, which is vital to its performance.

If you notice a decline in your vehicle`s air conditioning performance, especially at low speeds or while idling, it could be due to a malfunctioning radiator fan. Insufficient airflow caused by a faulty fan can impair the cooling efficiency of the air conditioning system.
Your radiator fan should kick in at about 200 degrees Fahrenheit. If you notice your vehicle is overheating or at the very least running hotter than it normally does, listen for the fan to see if you can hear it.
If the fan isn`t operating properly, it can lead to overheating fast and stop you in your tracks. Prolonged overheating can also damage engine parts, so it`s important to get the problem checked out as quickly as possible. Suspect the radiator fan has failed?
Please Note: You can connect a 3 Pin Fan to a 3 Pin or 4 Pin header on the motherboard. The fan will function normally no matter type of fan header is used.
The 4-wire fans have a PWM input, which is used to control the speed of the fan. Instead of switching the power to the entire fan on and off, only the power to the drive coils is switched. The PWM signal drives the fan directly; the drive FET is integrated inside the fan.
The average cost to install ceiling fan wiring can run between $350 and $2,000. If the area has no circuits, it can cost an additional $1,000 to $2,000. If the installation area has never had a ceiling fan, a mounting kit and a fixture will need to be installed. An electrician will then run power to the location.
It can be used to allow separate control of the light and fan on a ceiling fan, if the other end is found and properly connected. If it was unused and you don`t need it, just cap it off with a wirenut and leave it alone.
Can a Radiator be Repaired? It is possible to repair a cracked radiator if the crack is small enough, but it`s important to remember that your radiator is subjected to high temperatures and pressure during normal operation, so the product you use must be designed for that environment.
As long as the damage isn`t severe, repairing your radiator may be a much better option. A professional technician can evaluate the overall condition of the part, ensuring that your radiator won`t fail again shortly. If your mechanic discovers more damage or weak spots, then those can be repaired at the same time.
Pins: The leads in a 3-pin connector are designated for power, signal, and ground. In a four-pin variant, the fourth lead is a control lead; in a fan application, it would control the speed of the fan. These connectors are often available in low halogen or halogen-free versions, especially in those used in appliances.
We`ll jump right into the heart of the matter: An electric fan is the better performance solution, freeing up maximum horsepower and mpg. But it`s not always the better cooling solution.

A three pin connector is basically power (5/12 volt), ground, and signal. The signal wire measures how fast the fan is moving without any controls for the fan speed. With this type, fan speed is typically controlled by increasing or decreasing the voltage over the power wire.

Radiator valves have numbers or symbols to represent how much heat the radiator is putting out. Normally, these numbers range from 1 – 6. Turning the valve to 3 should give you a room temperature around 20°C. Each number above or below then represents a single degree.

If the wire on my radiator fan is bad, do I have to replace the entire fan?
ANSWER : A broken wire can generally fixed, but if the break is too close to the connector, you may want to replace the connector itself. If there is any corrosion inside the connector, then definitely replace the entire connector and the component it connects to for the best result. Consider having an experienced technician, such as one from YourMechanic, come out and take a closer look to offer a more personal diagnosis on the radiator fan.
I had my radiator replaced also my lower radiator holes replaced and my car keeps shaking really bad when the car is still
ANSWER : The shaking could be the result of a number of issues, including the engine having a misfire (not firing on all cylinders). The radiator replacement would not have created this condition. The vehicle should be inspected in order to diagnose this issue. A YourMechanic certified mechanic can come to your home or place of business to perform a car is shaking or vibrating inspection on your vehicle.
fan wiring is wrong
ANSWER : There are aftermarket electric fan controllers that enable the fan to be turned on by a temperature sensor or by a switch inside the cabin. This is a much safer alternative than to tap into the vehicles ignition wiring. The kits use a power source with circuit protection so there aren’t any hot wires or sparks to worry about. If the fan draws too much current through a small gauge wire, it may cause a fire. If you need help having this checked, a certified professional from YourMechanic can come to your car’s location to diagnose the electrical issue and let you know what needs repair.
I have issues with my radiator and radiator fan assembly.
ANSWER : You are correct in thinking that the combination of leaking radiator and non-functioning cooling fan is contributing to your overheating issue. Generally, modern radiators are not repairable and will need to be replaced entirely. The cooling fans can also be sourced from a used parts dealer. It will be used, but less expensive than a new set of fans. Replacement just means that it is designed just like the OEM unit and should fit perfectly. A certified technician, like one from YourMechanic.com, will be able to inspect or replace these components for you, if you are not comfortable doing the job yourself.
Radiator fan cycles on once then never again
ANSWER : Hi, thanks for writing in. There is a pressure sending unit that is used by the AC system that runs the radiator fans to maintain proper head pressure (mounted on the top of the accumulator). If this unit is defective, the computer goes into a default mode and runs the fans. I would recommend having an expert from Your Mechanic come to your home to diagnose and repair. I recommend having one of our certified automotive technicians from YourMechanic come to your home or office to inspect, diagnose, and repair the issue.
I have a bad oxygen sensor, bad power steering sensor, and a bad cam shaft sensor? Should I replace any of them?
ANSWER : When you say you have three bad sensors I can only assume you have had them tested and the end result is three bad sensors. If they tested bad then they should be replaced. The power steering sensor senses the load of the steering on the engine so it can raise the idle during parking maneuvers. The O2 sensor is used for fuel control and it may effect engine power and fuel mileage. The camshaft sensor cay cause no starts, engine running problems and all three will turn on the check engine light.
fan somehow putting hole in radiator
ANSWER : Hi there. If all the mountings are secure, the only thing I can think of is something that is pushing the fan into the radiator. Have the engine and transmission mounts checked. If the engine and transmission are moving around more that normal, the engine may be bumping the fan into the radiator. You may want to try having another qualified professional take a closer look at the car in order to see if they can pinpoint the cause of this problem.
Radiator fans wont turn off unless I turn off the car, why?
ANSWER : It sounds like you have checked just about everything that controls the fans other than the fan power relay itself. As you may know the coolant fan relay turns the fans off and on by receiving information from the coolant temperature sensor at specific temperature thresholds. When this relay is not working properly, this can cause the fans to come on intermittently, stay on all the time or sometimes not at all. When this happens you will notice a temperature spike and drop occasionally as the fan comes on and off. I would suggest having an expert from Your Mechanic come to your home to diagnose your coolant fan.
