I have to repectfully disagree with some of the others. I would NEVER replace a good fan and thermal fan clutch setup with an electric fan. No electric fan will outperform a really good engine driven fan,
I agree 100%. This car is already just on the edge of overheating. Electric will be big mistake 
I know diesel fords have been running an electrically actuated engine driven fan for years. Can't get straight electric to move enough air.

if your cooling issues are at 40 mph +, the fan has nothing to do with it. Overheating at slow speed indicates airflow issues,high speed heating does not. (with rare exeptions) There is enuff air moving past thru the radiator from the movement of the car.
Also agree 100% but he did say it comes up on the grades, and stays up. Not that it'll run hot on flats. I think the trans cooler is the way to go. The trans makes a lot of heat.

But 210 is not that hot. If that's as hot as it gets ever, I would not be too worried about it.
I also agree, although it can be nerve racking.
I put a remote trans cooler on the winni I tow with. It is mounted by the rear dif, with it's own electric fan. The cooler is huge. It's from a 06 superduty ford diesel. The fan is from a K car radiator.
Huge difference. I switch it on on the hills. On a hot day, if I leave them on by mistake, it cools the motor down an aditional 10 degrees.
I think a remote trans cooler is a great idea. Just plumb it in the return line from the rad trans cooler. Then you still get engine warming on the trans fluid at cold start, and with the fan off, it won't make it too cold.

i'm surprised no one has asked this yet...but where is your temp sensor located? If it's "in-line" comeing out of the trans, that is the hottest point, and seeing 210 there isn't too scary.
On the other hand, if your temp guage is IN the trans pan, seeing 210 THERE, means that even after it got past the trans cooler, its STILL 210. THATS a problem.
So...where is your temp sensor located?
EDIT: OOOPS!!! I just realized that you are referring to engine temp....not trans temp. sorry 'bout that! For what its worth....if the trans temp is getting too hot, it could be effecting your radiator temps. If you do a lot of towing, I'd highly recommend a trans temp guages, preferably, in-line, as close to the trans outlet as possible. If you're running 210 engine temp, you can bet the trans is getting pretty hot too.....

Stay away from electric fans. They won`t move the air volume of an engine driven fan and you won`t find them on anything that`s designed for real work like my little pickup (36" rad and seven blade clutch).
A clutch fan working CORRECTLY will not use any more power than necessary.
Just finished load testing some 3,989 cubic inch, 3,000 horsepower V16 mitsu diesel generators and guess what cools them.
Tell THIS to the Diesel Boyz !
The reason why the OEM runs CF's on "commercial type vehicles" ...is that they see alot of idling ..... and if there is an electric fan failure at that position ... that will kill the engine.
And HORSEfeathers to the electrics not being able to pull/push alot of air ... AND saying that a CF will not use any more power than necessary. Again .... tell, THIS to the Diesel Boyz that see up to 2 mpg by removing that CF. PLUS ...talk to the OEM engineers on why they use electrics on most all of their production vehicles.

Even if an electric fan will save some mpg, that's not what is the goal here. Looking for better cooling.
I know from my own experience, I have never installed an electric fan on anything, and then saw an improvement in overall cooling. Gains at idle only. Never while on the road.
If anything, since cooling is the main complaint, I would even consider a ridged fan on an application like this.
