If you contact Peter at TDIParts.com he can get you a compatable fan for not too expensive (IIRC it was about $90). The only problem is that on the the first and third speeds are wired up. (On the stock setup the first speed is activated by the first level of the rad temp switch and the AC being switched on, speed to is activated by the 2nd level of the rad temp switch or the AC high pressure switch, and the 3rd level is activated by the coolant temp switch on the head's side coolant flange.) I wired my ex-ecodiesel so that speed three would be activated in place of speed 2. You only have to move one wire on the relays up by the coolant bottle. The smaller relay does speed 2 and the larger one does speed 3.

If you are in a junkyard and spot the fan motor in a Mk3 VR6 you'll see that the motor is the same power, and has the same connector. But the mounting tabs are in a different spot, and the fanwheel is different

The OE fan system uses 450 watts on high speed. It moves a LOT of air.

and will only last about 5-10 minutes at this speed... ask me how i know :lol:

i thought the resistor pack was for the a/c continuous duty cycle, and then the a/c high temp switch or thermoswitch to kick the fan into medium or high? cars without a/c do not have the resistor to get the additional 3rd low speed...

Right, the resistor pack slows down the middle speed to create the low speed for the first level of the rad thermoswitch and AC.

FWIW the wiring diagrams for that fan system aren't in the Bentley manual. They are on Bentley's website though. But even those aren't totally complete, they don't show the temp sensor on the side of the engine. Also, the 50 amp fuse mounted to the bracket for the middle and high speed relays runs both the middle and high speed. The low speed one is on the normal fuse block.

Why buy something that you know is lowest-bidder Chinese knockoff stuff when you can buy the original OEM stuff with the actual manufacturer's brand on it for not much more? (Granted, some of that is made in China, too, but a lot of what eMiata sells is knockoffs.)

I prefer AutohausAZ.com for most of this stuff... in most cases, they only sell OEM equivalent or better parts. If they don't have something, I fall back on VW-specific vendors such as 1stVWParts and World Impex.

1st things first- I have to get everything back together so I can start testing/troubleshooting.

I would buy good, used fans before a Chinese unit. I am not stupid, and do not prefer to buy chinese over oem, that is just nuts.

I am an Engineer for a government contractor and can make the appropriate mechanical decisions on whether to buy oem, or aftermarket. Thanks for the suggestions.

So, I am a lucky guy with a wife that really likes VW's. She has a Passat 5 speed GLX VR6 wagon.

We are going to resurrect the Eco! I called ThePartsPlace and ordered a New, fully assembled Cylinder head.

It should be here tomorrow. I will post some pics. I will be port matching the intake and cleaning up the cyl head also. :twisted:
