Keeping your vehicle cool under all conditions is a huge part of maintaining peak performance. One of the main components of this system is your Honda Civic fan. The cooling fan in your Honda is directly responsible for drawing fresh air through your radiator.
As your vehicle is at speed, your Honda Civic fan should switch on automatically. There is one cooling fan switch that is mounted in the thermostat housing of your SOHC engine that controls the Honda Civic fan. If your Civic fan has died or you notice your Honda running hot, you may need a replacement Honda Civic fan.
When upgrading your Honda Civic fan, there are many options available to you online. Many of these fan upgrades will provide you with a high performance Honda Civic fan that mounts to your radiator. Others may want you to upgrade your radiator completely to a full core unit instead of a half.
Either way, when you are looking for the best way to replace your Honda Civic fan, this guide can help. Today I’ll be showing you how to replace the Civic fan in a 1997 Honda Civic SOHC hatchback.

If you are looking to replace your radiator or cooling fan, you may be wondering if you overheated your vehicle. Because the Civic engine in your Honda is aluminum, excessive temperatures can cause engine failure. Make sure to prevent this from happening by looking at the best Civic cooling fan online.
Before you begin the job of replacing your Honda fan, you’ll need to drain the coolant. Make sure that your Honda is cold before you jack up the front of the car and drain the radiator. Once you have the radiator fully drained, you can remove the Honda overflow tank.
Open your Honda Civic radiator cap to allow free flow of coolant. When the coolant is drained, you can begin removing the 10mm bolts in your Civic radiator stays.
When you have your radiator stays removed, you can begin disconnecting coolant lines. There’s a coolant feed from your Civic thermostat housing, and the return that goes into your engine. These hoses can be brittle due to heat and time, so take care when disconnecting these radiator hoses.
Now that your Civic radiator hoses are removed, you can lift the entire radiator assembly out of the Honda. If you are upgrading to an aftermarket radiator, now is a great time to prepare it. Aftermarket radiators can feature improved flow and cooling characteristics and hold more coolant as well.
Make sure to check your Honda Civic fan thermostat switch. This switch is located in the thermostat housing of the D16 engine. If this component is broken or the connector clip is smashed, you may need to install an aftermarket fan switch. Another huge upgrade you may want to look at is installing slimline fans.
Now that your Honda Civic fan and radiator have been removed, it’s time to swap fan assemblies. When you have the new fan mounted to your Civic radiator, it’s time to reinstall.
Once you have everything put back together, make sure to fill full of coolant. Start your Civic and ensure that there are no leaks before driving off. Have any questions about our guide to replacing a Honda Civic fan?
