The cooling system is an essential part of any car, and the Infiniti G35 is no exception. The cooling system ensures that the engine stays at an optimal temperature, preventing damage to the engine components. The cooling fan is a critical component of the cooling system, and it is responsible for pulling air through the radiator to cool the engine. In this article, we will discuss the 2005 Infiniti G35 cooling fan wiring diagram, including its function, components, and troubleshooting tips.
What is the Cooling Fan?
The cooling fan is an electric motor-driven device that helps regulate the temperature of the engine. The fan pulls air through the radiator, which cools the engine. Most modern cars have an electric cooling fan, which is controlled by a relay and a temperature sensor. The relay receives a signal from the temperature sensor, and it switches on the cooling fan when the engine reaches a specific temperature. The cooling fan will continue to run until the engine cools down to a safe temperature.
Components of the Cooling Fan System
The cooling fan system in the 2005 Infiniti G35 consists of several components, including:
| Component | Description |
|---|---|
| Cooling Fan Motor | An electric motor that drives the fan blades to pull air through the radiator. |
| Cooling Fan Relay | A switch that controls the power supply to the cooling fan motor. |
| Temperature Sensor | A sensor that monitors the engine temperature and signals the cooling fan relay to switch on the cooling fan when the temperature reaches a specific level. |
| Fuses | Protective devices that prevent damage to the electrical components in case of a short circuit. |
| Wiring Harness | A set of wires that connect the components of the cooling fan system. |

Testing the Cooling Fan System
If you suspect that your 2005 Infiniti G35’s cooling fan system is faulty, here are some troubleshooting tips:
Step 1: Check the Fuses
Check the fuses that protect the cooling fan system. Locate the fuse box, which is usually under the dashboard or the hood, and check the diagram to identify the cooling fan fuse. Use a multimeter to test the fuse and replace it if it’s faulty.
Step 2: Check the Wiring Harness
Check the wiring harness that connects the cooling fan system components. Look for signs of damage, such as frayed wires, loose connections, or corrosion. Use a multimeter to test the continuity of the wires and repair any damaged wires or connectors.
Step 3: Check the Temperature Sensor
If the fuses and wiring harness are okay, check the temperature sensor. The temperature sensor is usually located in the engine block or the thermostat housing. Use a multimeter to test the sensor’s resistance and replace it if it’s faulty.
Step 4: Check the Cooling Fan Motor
If all the above steps fail, check the cooling fan motor. Use a multimeter to test the motor’s resistance and continuity. If the motor is faulty, replace it with a new one.
FAQs
Q. How do I know if my cooling fan is working?
A. You can tell if your cooling fan is working by listening for its operation when the engine is warm. The fan should turn on automatically when the engine reaches a specific temperature. You can also check by opening the hood and looking for the fan blades spinning.
Q. Can I drive my car if the cooling fan is faulty?
A. It is not recommended to drive your car if the cooling fan is faulty. If the engine overheats, it can cause significant damage to the engine components, leading to costly repairs.
Q. How much does it cost to replace a cooling fan?
A. The cost of replacing a cooling fan varies depending on the make and model of the car and the mechanic’s labor charges. On average, it can cost anywhere from $200 to $500.
Q. Can I replace the cooling fan myself?
A. If you have experience working with electrical components, you can replace the cooling fan yourself. However, if you’re not familiar with the process, it’s best to leave it to a professional mechanic.
That concludes our discussion of the 2005 Infiniti G35 cooling fan wiring diagram. Remember to keep your cooling system in top condition to avoid any potential engine damage or costly repairs.
