Electric fans are an important component of any vehicle, and if you are looking to install one, you have come to the right place. In this article, we will discuss the electric fan relay kit wiring diagram and help you understand how to install one in your vehicle. Whether you are a beginner or an expert in automotive systems, this guide is sure to be helpful. So, let’s get started!
What is an Electric Fan Relay Kit?
An electric fan relay kit is a set of components that allows you to install an electric fan in your vehicle. It includes a relay, a fuse, a wiring harness, and a temperature sensor. The relay is responsible for turning the fan on and off, while the fuse protects the system from electrical surges. The wiring harness connects all the components together, and the temperature sensor ensures that the fan runs only when the engine is hot enough.
Most electric fan relay kits are universal, meaning they can be installed in any vehicle. However, it is important to check the compatibility of the kit with your vehicle before making a purchase. Different vehicles may require different wiring configurations, and you need to ensure that the kit you are buying is compatible with your car.
Why Install an Electric Fan?
Electric fans have several advantages over mechanical fans. First and foremost, they are more efficient in cooling the engine. They consume less power than mechanical fans and do not rob the engine of horsepower. Additionally, electric fans are quieter and less intrusive than mechanical fans, which can be loud and obtrusive. Finally, electric fans allow more flexibility in mounting options, since they do not have to be attached to the engine with a mechanical fan clutch.
Installing an Electric Fan Relay Kit: Step-by-Step Guide
Before beginning any installation, it is important to read the instructions provided with the kit. The following steps are a general guide to installing an electric fan relay kit:
Step 1: Locate the Right Spot for the Fan
The first step is to decide where you want to mount the fan. The most common location is in front of the radiator, where it can draw air through the radiator and cool the engine. However, you can also mount the fan behind the radiator, on the engine side, or even on the firewall.
Step 2: Mount the Fan
Once you have decided on the location, mount the fan using the hardware provided with the kit. Make sure the fan is securely mounted and does not vibrate or wobble.
Step 3: Mount the Relay
Mount the relay in a location that is easily accessible but protected from moisture and heat. Use the hardware provided with the kit to secure the relay to a sturdy surface.
Step 4: Install the Temperature Sensor
Install the temperature sensor in a location where it can measure the temperature of the engine. The most common location is in the radiator fins, where it can detect the temperature of the coolant. Use the hardware provided with the kit to secure the sensor in place.
Step 5: Install the Wiring Harness
The wiring harness connects all the components together. Start by connecting the fan to the harness, making sure the polarity is correct. Then, connect the harness to the relay, following the instructions provided with the kit. Finally, connect the harness to the temperature sensor, again following the instructions provided with the kit.
Step 6: Install the Fuse
Install the fuse in the fuse holder provided with the kit. The fuse protects the system from electrical surges and prevents damage to the components.
Step 7: Test the System
Test the system by starting the engine and letting it run until it reaches operating temperature. The fan should turn on automatically once the engine reaches the temperature set by the temperature sensor. If the fan does not turn on, check the connections and make sure everything is properly connected.
