The BMW E36 is a beloved model among car enthusiasts, known for its balance of performance and style. One popular modification for this vehicle is the installation of an electric fan, specifically the Mishimoto Electric Fan. This upgrade can enhance cooling efficiency and improve engine performance. In this article, we will provide a step-by-step guide to installing a Mishimoto Electric Fan in your BMW E36, along with a performance review of the upgrade.
Why Upgrade to an Electric Fan?
Upgrading to an electric fan offers several benefits over the traditional mechanical fan. Here are some reasons to consider this modification:
- Improved Cooling: Electric fans can provide better airflow and cooling efficiency, especially in high-performance situations.
- Weight Reduction: Electric fans are generally lighter than mechanical fans, which can help reduce the overall weight of the car.
- Increased Engine Efficiency: By eliminating the parasitic drag of a mechanical fan, the engine can run more efficiently.
- Customizable Fan Speeds: Many electric fans come with adjustable speed settings, allowing for optimal cooling based on driving conditions.
Tools and Materials Needed
Before starting the installation, gather the following tools and materials:
- Mishimoto Electric Fan Kit
- Wire Strippers and Crimpers
- Socket Set
- Wrenches
- Electrical Tape
- Screwdriver Set
- Zip Ties
- Multimeter
- Cooling System Flush (optional)
Step-by-Step Installation Guide
Step 1: Prepare Your Vehicle
Start by ensuring your vehicle is parked on a level surface and the engine is cool. Disconnect the negative battery terminal to prevent any electrical shorts during the installation process.
Step 2: Remove the Stock Mechanical Fan
To remove the stock mechanical fan, follow these steps:
- Locate the fan shroud and remove any screws or clips holding it in place.
- Use a wrench to loosen the fan clutch nut, turning it counterclockwise.
- Carefully pull the fan away from the engine and set it aside.
Step 3: Install the Mishimoto Electric Fan
Next, install the Mishimoto Electric Fan by following these steps:
- Position the electric fan in the same location as the stock fan.
- Secure the fan to the radiator using the provided mounting hardware.
- Ensure the fan is centered and does not obstruct any other components.
Step 4: Wiring the Fan
Wiring the electric fan is crucial for proper operation. Follow these steps:
- Connect the positive wire from the fan to a switched power source, such as the ignition or fuse box.
- Connect the negative wire to a suitable ground point on the chassis.
- If your fan includes a temperature switch, install it according to the manufacturer’s instructions.
- Use electrical tape to secure connections and prevent shorts.
Step 5: Reconnect the Battery and Test the Fan
Once the wiring is complete, reconnect the negative battery terminal. Start the engine and test the fan operation:
- Turn on the ignition and observe if the fan activates.
- Check for any unusual noises or vibrations.
- Monitor the temperature gauge to ensure proper cooling performance.
