viscous fan

Apparently Viscous is the way to go - as designed by Landrover.......

I thought about a second set of air con fans. You can pick up a pair on ebay for not much money. Then you can have your 2 new aircon fans as your viscous replacement and 2 existing ones as backup...

Just pull one from a modern car from a breakers/scrappers

just make sure you get enough cable to connect it to your existing wires - spend your savings on beer

Good idea, not so easy over here

Viscous fans are an abomination Used only by manufacturers stuck in a 70's time warp.

Slim ones off Volvo or the like would be better

But, but, but they were designed by "highly paid and highly trained engineers" and we shouldn't change what is obviously the ultimate solution

True, kiddies straight out of uni in the 70's with about as much common sense as a turd

When did yu finish yo training?

but they work more than adequatley whats the point of changing something that works ,youd expect them to fail on 10 or more year old motors ,simple enough to change unless you dont know how to undo them

Viscous fans in those days were the latest design concept. And a must have feature. But to be honest a quantum leap from the fixed fan. So an understandable addition. Electric fans in those days were generally something they used on the design office desk in summer.

In the 70's maybe, but by the 80's wifes Renault and my MR2 had only electric fans as did many other cars.
As I said, P38 design stuck in a 70's time warp or LR had stock left over from the Classic.

cars only switched then because engines were fitted tranversely most longitudinally kept simple viscous system ,some of those electric systems were prone to more heat shock than the viscous ,obviously the future is ecu controlled electric

Oh for the 70's/80's. British motor industry at its best. The classic Rangey had exact same door handles as my old Triumph Tr7, another masterclass of British design (from the parts bin).

Don't you mean the TR7 had the same door handles as the older Range Rover?

Glad they introduced them as well. Have you ever tried to change the 6 foot long fan belt on i think an old transverse Pug. It was a bloody work of art.

He He, the only belt I've seen on a car the did a 90 degree turn at right angles to the crank pulley. Truly the work of a madman

Yes. I should have said the Tr7 had the same door handles as the Morris Marina which had the same door handles as the Rangey Classic (and no doubt a few others).

Quite a lot had the same ones. Some of the stuff produced by BMC/British Leyland was truly shocking. They went out of business for a reason unfortunately. But then again Rootes group stuff and Vauxhall around the same time were not any better. Ford just about managed to scrape through with the skin of their teeth.

Viscous fans aren't as bad an idea as they sound - especially on an off-roader, you are spinning the fan up as soon as you're putting the engine under more load, where as an electric fan responds to heat being dumped into the system - after the event. On the down side when you're ticking over after loading the engine the viscous fan is running slowly.
