I don't know if the 1.6L is the same or uses a similar fan or thermostat setup (two fans, dual speed); the above info is listed for the: 1.9L TDI, 2.0L and 1.8T gas engines.

My guess would be it is possible they are very similar or the same; also, VW tends to use similar parts and possibly specs, in their platforms, in this case the Mark IV platform (Golf, Jetta, New Beetle).

Ok, always good to confirm things; I asked, as there was a "blank" hole, you were running hot and I worked on a Jetta 1.8T one time, some just removed the fan, it was gone! Based, upon my own New Beetle 1.8T, I think VW does do some "localization" modifications; based upon the climate of the delivery area of the vehicle. My car, for example: had a "hot weather package" on the option codes; listed, when I decoded the vin number one time and I wouldn't be surprised, if your car was delivered to a hotter climate, VW may have added a second fan, to help keep it cool. My 1.8T, also has a electric auxiliary coolant pump; that runs, circulating coolant to turbocharger, to keep it cool and runs for awhile, after you shut the engine off.

Well Mr Billy, With your guidance and assistance and my Too-dumb-too-quit attitude, we have finally fixed one smoking 1.6L Luna Beetle Cabriolet, Took her for a 20 mile drive today breaking in the rings as instructed. Purrs lovely, I think the ECU has to settle down everything a tad but idles lovely! drives like a new car! no sounds, no smoke! No overheating, was running 89-90c when driving about. No smoke in traffic. and the coolant comes up to the max line on bottle when hot, PERFECT.

So to fix your 1.6L smoking, all u need to do is a full engine rebuild and get a new battery and exhaust. Thanks and goodnight...(jk)

But yes, my issue was the OIL RINGS being seized and not turning separately and a busted CAT pipe. (Possibly caused by a faulty thermostat making the engine too cool and fouling the rings)

You don't need many specialist tools to do this on your bug, and if you're somewhat handy with them i recommend getting a Haynes manual and saving yourself a grand in garage bills.
Handy tip: YOU CAN TAKE CYLINDER HEAD OFF WITHOUT TOUCHING THE VALVES OR CAMS MEANING U DONT HAVE TO MESS AROUND WITH ENGINE MOUNTS, I RECOMEND A BENDABLE INSPECTION MIRROR AND CIRCLIP PLIERS TO ADJUST THE TIMING TENSIONER IF YOU USE THIS SILVERGRIFFIN21 CHEAT. But u might as well replace the valve steam seals and re-grind the valves while the head is off....might as well..right?

Things I have replaced:

  • Valve stem seals
  • Piston rings
  • CAT pipe
  • Cylinder head gasket
  • Battery
  • Intake manifold gasket (upper and bottom)
  • Valve cover
  • Oil
  • Spark Plugs
  • Coolant
  • Coolant flange sensor
  • Thermostat
Things I fixed:

  • Brake booster vacuum hose
  • Stripped TB bolt
  • Bore honing

Things I HAD fixed:

- Cylinder head re-surfacing
