Clutchless Fan Replacement for 200tdi

I just installed a clutchless fan, replacing my viscous fan on my 1984 d-90 with a 200tdi. The truck was running a little hot as the viscous fan was not working properly. The direct drive fan supplied by Jim Pendleton, a member on this site. So far, the car seems to be running cooler. I am sold on the direct drive fan replacement for the viscous fan.

Awesome ... You are working the engine harder to cool itself ... Prepare to lose gas mileage and have extra fan noise. The great thing is that the extra noise can be a constant reminder that you should have addressed the cause rather than just mask the problem.

Why not swapped the original fan for an electric one? I did that myself and the fan only started once in... 3 years. The 200 tdi doesn't produce a lot of heat. Your new direct drive fan might be a bit too much and you'll find yourself running a cold engine. Too cold = less performance for more fuel. Remember a diesel engine should run sweetly at normal temp. Your 200tdi might have a cooling problem?

Well said.

When my 200tdi was running hot I diagnosed it as the viscous fan. Once replaced, the truck runs right at temp.

Mike sorry that was probably a bit uncalled for ... I had my sarcastic hat on last night ... actually because I'm English I rarely take it off.

The 200tdi should run nicely without the need for a fixed fan ... the standard viscous fan is designed to work in a complimentary arrangement with the correct thermostat in the engine. The water in the engine is a pressurized system and is very efficient at cooling the engine.

The viscous fans do age out ... and a new one should bring your system back to normal ... however if it doesn't it could be indicative of other issues ... and those should be addressed not masked.

If you don't lose water and your radiator is evenly hot from top to bottom then it's probably just in need of a proper fan clutch.

A fixed fan is probably only useful for situations where the vehicle rarely moves ... like running machinery via the PTO ... otherwise its really just a waste of gas.

Kenlowe fans seems to be all the rage in the UK. Claims to save fuel, improve performance and deal with potential overcooling issues. Does anyone have experience with them?

I think I have bit of an overcooling issue on my 300tdi. Runs very cool for the most part.

You are better to get a real automotive fan and mount it properly. The key to a successful electric fan conversion is to do the mount and electrical to an OEM level. For the TDIs, the Taurus 16", 2 speed fan fits quite easily in the stock shroud mounts. Here are some pics of my install: http://www.red90.ca/photos/land-rovers/taurus-fan/

It will not save any fuel. It will not fix overheating unless the fan viscous unit was the cause. It is more complicated so will reduce system reliability...

It does allow for safer deep water crossings. It does free up a lot of space in a 200TDI for engine access.

Fans reduce temperature once the thermostat has opened - basically after the engine has reached proper operating temp. Over cooling would be the thermostat opening too early ... nothing to do with fans operation.

Kenlowe fans are well respected in the UK. The fuel savings and performance come from the fact the engine doesn't have to turn the fan at all ... their is work required to spin a viscous fan even when it's not locked on ...

I personally don't like the idea of grafting on an electric fan that wasn't designed for the job.

I'm sure Kenlows' are grrrreat, but I prefer the viscous that my (in this case, Td5) came with. not too noisy and designed to work from Arctic to desert conditions.... :-)

Correct! Which is why you need to design the system for the job or leave well enough alone.

Well, thanks for all of the input. I guess I'll find out whether this works for me one way or another. Today it was over 90 degrees and the engine temp guage stayed at the exact mid range. I know some prefer the intended / engineered viscous fan and others like the electric fans (ie kenlowe). To each his own and variety is the spice of life. Thanks for all of the comments.

I ran my 200 to Montauk and back at 90 degrees last weekend with no fan, and it never went above 195, even in stop and go traffic. I did have a flexilite with me just in case. (been too lazy to install since the one in my 90 has only turned on twice in 3 years.)

In the winter you might want to get a cover for your grill. The always on fan might not let the engine heat up enough. I run one in the dead of winter and the diesel runs much better.

I was also concerned about running cold in the winter, and got a rovers north grille cover from one of the members on this site. For what it is worth, my truck seems to run smoothest when it runs a little cool. But, I agree, it might run too cold in the winter, and the cover may help guard against that.

If your thermostat does not leak a rad cover is not needed. It gets -40 here and there are no problems.
