Cheap Electric fan conversion - any one done one?

Thing is there fine just day to day but when your asking that bit extra, like when towing up a steep hill. That's when they become woefully lacking and forever after you'll have one eye on the temperature gauge.
IMO they're just not worth the hassle and expense.

I have a kenlowe fitted to my disco. I also have a full width allisport intercooler infront of the rad. I tow a transporter trailor and landy on the back, and have never seen the temp gauge move. I do have the larger of the two kenlowes fitted, but that shouldnt make that much difference.
It is niceto have a hot heater blower in under half an hour too. :)

The type of fan you have shouldn't make any difference to how quickly it heat sup though, that's what the thermostat does.
Admittedly the TDi runs cool most of the time, Julie's had lost most of the fins on the rad and it was still woring fine, 'till it bust open on the motorway and cooked the head :roll:
My overheating problems were with the LSE, I tow a big 'van and often have the airconn on too, the electric fans on that are useless (for some reasn they only fitted 10" fans to the soft dash). Even though I'd flushed the rad out I eneded up replacing it and the viscous hub, I'm happy to report it now runs quite cool, unless you deliberately make it overheat.
There's no denying though that the best airmover is a viscous fan that works properly.
Sharpshooter:
It will make a difference, as the viscouse fan is always turning over. Thus fanning the engine bay.

Your running a diesel of only 2.5 litres. Now try it with a 4 litre jeep with an already marginaly sized but brand new rad with an air con rad in front. Fine for the most part but ask it to work hard and the 2 electric fans just couldn't shift enough air.
The main electric fan I used was the biggest and most powerful I could find, a pacet profan that shifted 2139cfm @ 3.75mm static, compared to around 3500cfm for the viscous fan. The second electric was the original aircon fan.
I did my homework and spent my money, time and effort. TBH it was a waste of time, had I just replaced the viscous coupling I would have had more money in my pocket and a whole lot less worry. oh! and I never saved a penny on fuel :roll:
In fairness my 3.9 disco seems to be overcooled (non aircon model) and I have run it without a fan at all, which was fine if I didn't get stuck in traffic for more than 20 minutes. but for the sake of £50 and an hours work is it worth all the hassle of trying to fit an electric fan then set it up to come on and off at the right times etc, not to mention the wiring in of override switches.
I'm not trying to start an argument, i'm just making the point that the cost versus gain has to be carfully looked at, that why I put a new couping on my disco instead of electric.
