Hi All,

Simple opinions please.

Is it worth the hassle and cost of fitting electric fans to replace the viscous one (noise/consumption/power)? Does the engine warm up faster and is the cooling more efficient?

Has anyone done this and did they buy a kit or trawl the breakers looking for fans (one big one or two smaller ones)?

What do you do after removing the fan given there is now a pulley missing? Do you need to go to the local Partco and hope they can come up with a belt of the right length/width or do you leave the pulley in place and just whip the fan itself off?

Cheers!

Malcolm

No need to buy a fan, if you have aircon just remove viscous fan and rig a thermostat in top hose through a relay to switch aircon fans on as rad coolers.
 
Having fitted 2 "Kenlowe" electric Fans on my MGB Roadster they "Usually" fit IN FRONT of the rad (Rather than where the Viscous fan is fitted) & blow INTO the engine.

As you have both the Air cons fans fitted there + the Gearbox Oil cooler it would be nye on impossible to fit them there on a Rangie.

I doubt you would have enought room BEHIND the rad (Even with the Viscous fan blades removed) Having fitted "A fair Few" Eletcric fan on "Classic Cars" you'd be surprised just how many people assume the Viscous fan BLOWS AT THE RAD it does'nt it SUCKS thru the rad pulling in Cool air accross the radiator surface.

On a scale of 1 to 10 ........... I'd give the idea a 2 .... Naaawww Don't do it!!!!

Or rig up a switch to bring on the Air Con fans to cool the engine Thermostat phile in the top hose & a relay to power them THAT would be far easier

I agree, just buy an adjustable thermostat and tap into the aircon wiring and use the existing fans, I can provide details if you wish:D
 
I read an article somewhere that stated that you didn't get anything like the same airflow from an electric fan vs a viscous.

Worth checking first...

On a V8 that's prone to get warm anyway is it really worth the risk?

You would get MORE AIR FLOW whilst "Standing Still" (Coz the fans are "Pushing" rather than "Pulling") when yer moving it would be roughly the same if not slightly more thru-put ect
 
hi all, id like to remove my viscus fan and replace with an electric one.is it better to buy the kenlowe or is the ac fan good enough ps the car raely leaves the city. many thanks for any advice
 
I've just removed a retrofit pair of electric fans off the classic and replaced the OEM viscous.. if you want them.. you can have them.

The AC fans are more than adequate on the diesel but not on the V8 which needs the viscous.
Kenlowe are pretty poor these days and overpriced. I would not trust a kenlowe to cool a V8.
