Replace radiator

Replacing the radiator fan assembly is a bit tedious due to the space you have to work with. VW recommends putting the radiator support panel into the service position to gain access. I found this to be quite difficult. I simply removed the entire radiator support to gain clearance. Make sure that the radiator is supported underneath while working.

Gaining access to the radiator fans requires removal of quite a few items. See our articles on Front Bumper Cover Removal, Front Bumper Removal and Radiator Support Panel Removal for more information.

Shown here is the radiator fan assembly for the Mk4 Jetta 2.
Figure 1

Shown here is the radiator fan assembly for the Mk4 Jetta 2.0. Replacement is a bit tedious, as there's a lot of flimsy plastic that can snap easily.

Locate the electrical connectors for the fans at the right lower side of the radiator.
Figure 2

Locate the electrical connectors for the fans at the right lower side of the radiator. You'll need to disconnect the top one first. Press the tab (green arrow) with a small pick and pull it apart.

The second electrical connection requires you to pull the plastic bracket for the fans out of the radiator fan assembly.

The second electrical connection requires you to pull the plastic bracket for the fans out of the radiator fan assembly. Use caution, as it's easy to damage the plastic. Once free, use a small pick to press the tab (green arrow) and separate the connector.

Now loosen and remove the T30 Torx screw underneath the electrical connectors (green arrow).
