Installing an aftermarket cooling fan can be a great way to improve the performance of your vehicle. However, it’s important to know how to wire the cooling fan correctly to ensure it functions properly. In this article, we’ll discuss everything you need to know about wiring an aftermarket cooling fan. From the wiring diagram to FAQs, this guide will cover all the information you need to know.

Wiring an Aftermarket Cooling Fan: Understanding the Basics

Before we dive into the wiring diagram of an aftermarket cooling fan, let’s first understand the basics of cooling fans. A cooling fan is a device that’s used to keep the engine temperature under control. It removes the heat from the engine and dissipates it through the radiator.

An aftermarket cooling fan is typically used to supplement the OEM fan or replace it altogether. The fan is usually driven by an electric motor, which is controlled by a relay and a temperature switch. The relay sends power to the fan, while the temperature switch turns the fan on or off based on the engine’s temperature.

Now that we know the basics of cooling fans, let’s look at the wiring diagram of an aftermarket cooling fan.
