200Tdi Electric Fan Preferences

I just ordered an Ex-Fan switch and am shopping for an electric fan setup for my 200Tdi.
I have seen that the Taurus setup may over tax my stock alternator. Will my stock alternator work? What else have you guys had success with?
Thanks!

All the electric fans I've ever seen have a thermostat controlling them.

That is correct. That is what the X-Fan switch is.

The Taurus fan is a great fit. You can use the low speed connector on it if you do not want as much draw. On high speed it will only come on for 10 seconds max. It will really never need the high speed.

My personal preference for control is the Dccontrol dual relay controller. http://www.dccontrol.com/relay_controllers.htm Waterproof and designed and built beyond OEM levels.

This was my install: http://www.landroveraddict.com/forum...threadID=56139 I used a Flex-a-lite controller as the Dccontrol one was not available. If I were doing it today, I would get the Dccontrol unit.

I have both VC and electric as I have AC. I wired up a thermostatic switch so the electric fan comes on at 205 if the AC is off (automatically comes on when the AC is on) and then the VC comes on at whatever temp it is supposed to (it was coming on at 220 climbing a huge grade with the turbo having massive boost leaks and dropping temp to 210). The switch is adjustable if need be (ie climbing off road on a hot day can have it on at what ever temp I want). I also installed an 82C thermostat so now fully loaded at 65-70 mpg i run 188-190F. Been a long road for me (as it has for most of us) but this set up is working well.

Just spent 2 weeks in southern California with my 200tdi 110. Running the viscous fan only fresh tstat and a recored radiator. Had a higher efficiency core put in last summer. Also ran the cooling system depressurized the whole trip and had no cooling issues whats so ever. Hottest temps i saw on the vdo gauge were 195 and thats running about 1150 egts up a long grade Normally stays right at 190. Had a full length roof rack and rtt on as well for the trip.

RovingRyan that sounds perfect! How did you run the system unpressurized and what are the specs on that rad? My temp is good but def climbs while I am climbing.

Sounds to me like your VC is not locking up early enough.

There is no way mine has ever been above 90 C (195 F) with the Taurus fan and it never is on for more than 10 to 20 seconds at a time.

Yeah when i took it in for the turbo boost leaks the shop figured that out as well and put a new viscous hub on, now i haven't heard it come on. warmest it got was 205 up a long climb. Not sure what temp the VC is supposed to come on but my electric fan is set for 205 and it works well

What? Is your mechanical fan not getting the job done? Or is the fan shroud just too unsightly?


Fwiw I've got a 200tdi radiator in my Series 1 and I'm using a Spal 16" fan. Fits perfectly.

The first worry was about the alternator. What alternator do you have? The fans never run enough to matter. Regardless, if you have a 45 A, it is best to at least change to the 65 A one. Besides the higher output, the voltage control is better.

I had my doubts but just came back from a freeway road test at 70 MPH. I think it is fine but I may still go electric anyway.

Pretty sure its a 65 A but I need to check to be sure. The motor came out of a Disco so it is whatever was standard for that.

My mechanical fan seems to keep my 200tdi cool enough, but then again I don't live at the fiery gates of hell like you do.

If it is a Disco motor, you can also add a 100 Amp unit as those were OEM and fit without problem.

My lower radiator hose developed a leak at the fused connection on day three of the trip so I wrapped it with some thin rubber and a clamp. After that I didnt want to push my luck so I ran the remainder of the trip with the expansion tank cap loose and wedged so it would not come off...This kept the system depressurized and I had no issues, although I had my doubts early on.

I had a local radiator shop do the recore.. Receipt doesnt really say anything useful other then HE 3 Row TQLF core

Quick update. I installed the fan today on the hottest day of the year so far. I started using Red90's write up as a guide and didn't like the way it was going to come out. I had a 300Tdi fan shroud laying around so I cut the Taurus fan out of the included shroud and riveted it into the 300Tdi shroud. It looks like a factory install.
