Volkswagen Radiator Fan Buyers Guide

If you think your Volkswagen's radiator fan is failing, you've come to the right place. In this article, we'll cover radiator fans, how to tell if your fan is failing, and why it's important to get a quality OEM fan. We'll also show you how to replace it and where to go for help.

What Is A Radiator Fan And Why Is It Important?

A radiator fan helps keep your car's engine from overheating. It really makes a difference during hot weather when you're sitting in traffic or the engine is idling. The radiator fan draws air through the radiator to keep your VW's engine operating at the right temperature. Depending on the size and shape of the radiator, your car will have one or two cooling fans. Without them, your car would overheat and eventually break down. Find more details about the job your radiator fan does in this post.

How To Tell If You Have a Failing Radiator Fan

If your VW's fan turns on and off regularly, it's probably operating normally. Most radiator fans have a temperature sensor that turns the fan on or off as needed. However, if your fan either never turns on or runs constantly, it could be failing. If you notice this, or other symptoms like overheating, odd noises from the fan or constantly blown fuses, you'll want to troubleshoot the fan. You can do this by:

  • Warming up the engine and watching to see if the fan comes on, and how often.
  • Testing the fan power with a volt meter.
  • Checking any belts connected to the radiator fan for wear or failure.

Fan failure can be caused from several issues, so taking your time to correctly diagnose the issue is a must. Learn more about troubleshooting your radiator fan in this article.

How To Replace A VW Radiator Fan

Replacing your radiator fan yourself is a task most can complete at home. Be sure you park your VW in a secure place and properly engage your brake before beginning so the vehicle won't shift unexpectedly. Also, be certain your battery is disconnected and have the following tools handy:

  • Assorted pliers
  • Screwdriver set
  • Metric socket set or metric combination box/crescent wrenches

Replacing the radiator fan on most VWs (with electrically powered fans) can be done in 4 steps, as outlined in this article.

Are OEM VW Radiator Fans Better Than Aftermarket?

You might save a few dollars by buying an aftermarket radiator fan, but it likely won't perform as well and will cost you more money in the long run. Here's why:

  • Aftermarket fans may not fit correctly: Only Volkswagen radiator fans meet OEM specifications and are intended to fit your exact VW model.
  • VW OEM radiator fans carry Volkswagen's warranty. If you have any problems during the warranty period, you can easily exchange the fan. Most aftermarket companies don't offer such a warranty.
  • An aftermarket fan may not last as long or perform as well - which means you'll have to replace it again, and sooner. Another way an aftermarket fan will cost you money, not save it.
