Use several ratchet wrench extensions to get to the battery retainer nut.
VW Cabriolet Radiator Removal and Installation
The radiator brackets slide into a slot on the radiator. Take the brackets out and use them on the new radiator.
That flex hose is the fresh air inlet for the engine. I removed it to get a better grip on the temperature sensor plug. The sensor is the brown thing in the center of the photo. We are looking at the left side of the engine bay. The battery tray is in the upper right of the photo.
Gently lift out the radiator. It is only held in by the two brackets on the top. The bottom has pins that fit into holes on the car. Save the rubber bushings on the bottom of the radiator.
There is a carboard air deflector on the left side of the radiator (driver side of the car). Save it also.
Oh, dont forget to disconnect the overflow hose, seen here in the bottom left of the photo. This hose is right next to the upper radiator hose.
This is a sure sign of a stupid mechanic. That is the factory spring hose clamp still in the middle of the hose.
The radiator out of the car. Four screws hold the fan to the radiator. Remove the fan and its shroud as a single part.
Attache the fan and shroud to the new radiator. Be careful with the screws because you are putting screws into plastic.
Transfer the temperature sensor to the new radiator. Keep the gasket, or replace if it is messed up.
The nice, shiny radiator back in the car, but not screwed in place.
