I know i have seen many post about cooling fans but I have a situation that I can not find in any threads. I have a 03' 1.8 turbo, We (Father and I) have replaces Intake valves, head, turbo, fuel pump, spark plugs, and MANY sensors. Now I have a small leak in a plastic T in the upper radiator hoses that has been dripping on the cooling fan motor, then all of a sudden the fans will not come on. I say it is because the motor has shorted out due to the leak, Father doesn't believe that is the motor he thinks it is just a fuse or relay. I can't seem to find a 4 wire/plug fan for under $300. Does any one know a secret on where to go? Also I have heard that you can splice a 3 wire into a 4 wire plug but is that save or recommended. I assume that I have a 3 speed fan for a reason, being turbo or something. Any input would be appreciated.

I bought the VDO/Continental oem fan. Passenger side from AutoZone and it was identical to the one that was in my beetle. Do you have a single fan or do you have dual fans? Got a Volkswagen part number for your fan?

Look up the parts here:

VDO / Radiator Fan Assembly Part Number: FA70006

Notes: Passenger side Single fan assembly.

rebuilt fan

I just had a similar issue and I knew you can remove the fans and remove the back cover on the fan and repair. Mine were just dirty from all the brush dust and so I just flush out with plastic safe cleaner ie maf cleaner. I would not pay 300+ for a fan that's only worth $60 either. I have not seen anybody actually wire a 3 wire fan to the 4 wire plug. The fourth wire(red) actually only gets 12v when the coolant sensor mounted at the front by the Y hose connection is at above 115 degrees Fahrenheit and puts both fans in high speed. And that signal comes through the relay panel mounted under the dashboard by the steering wheel. There is a diy thread around here titled summer is coming check your fans, you might want to do a search for that.

oh forgot to tell you that my problem wind up being the fan control module and the fans themselves binding because of brush dust/grime/dirt and whatever. good luck

It is a dual fan. The drivers side is the one with the attached motor that runs the passenger side fan. I believe. No I do not have a part number.

Dude, each fan has it's individual motor and the large driver side 4 wire fan part number which I believe you need is
1C0959455A It's a 345mm size, the small fan is a 3 wire and it's a 290mm size. both fans are in parallel and come on at the same time.
