the most problems i see with the elec is the conections. i have watched many V8 conversions with problems and even Marc has had his share of problems and he is quite meticulous with his thought process. some guys get it right but most i see using the aftermarket units end up with problems.
once again it comes down to preference and unless it works all the time i am not interested. after all one of the reasons i got into cruisers is because of their history of reliability and once i got into them i realised they can put up with my abuse to boot...
Toyota gauges <shiver>
cheers
 
Assumnig your clutch fan is working correctly, can you still trust it not to fail in the future when you are miles away from anywhere? Seems to me there is a lot of report on failer clutch fans out there to take a risk.

OZ or Canadian back country is not the place to break down..

Thanks

In Oz nearly all the cars and performance cars and a few 4wd are fitted with electric fans now days. Some of the problems with the D.I.Y fans are that the C.F.M of the electric fan does not match the original fixed or clutch fan. I have not found out what a standard Cruiser fan will push in C.F.M. but anyone can tell that it is a hell of a lot. Also with the big fan sets the alternators are not capable of driving them continuously as they were never designed to drive an electric fan or combo of them.Say for instance a 50 amp alternator when new probably makes 40/ 45 amps for real and when lights, aircon , stereo, amps and the fans are running there is simply not enough juice.Most of the newer vehicles are running 60/65 amp or better. Also the shroud is correctly designed to cover the radiator with the fan at the correct distance from the radiator for maximum effect. The benefit here is that the fan can be run at full speed while stationary or moving slow when its needed most. On some of the hot cars here the boys also fit timers so the fan can run for some minutes after the engine is shut down which is good as the water continues to surge through the radiator after shut down .On a moderate day at app 35/ 40 mph a clutch or electric fan should have turned off if the cooling system is in good condition and the air passing through the radiator should be doing the cooling.:idea: Then guess where we put our spot lights and high mount winches :o ,,,aahh love a Cruiser.:beer:

What do you do when your fixed fan goes through the bonnet [hood] or radiator.LOl. Why did Toyota change? Their Engineers are smarter then you or myself LOl.
 
LOL.... :)
Good question.... Can't answer for Toyota... I think the stock fan is quite strong not like some after market "flex fans" which can send blades through a chevy hood when they break.
Whats the diffence thoe a solid fan or clutch when they are both engaued both can fail
Its not a smart selling point for Toyota to put solid fans in.. its to LOL crude.


Thanks

oh my, i love this statement...
where to start?
vacumm pump on the back of the 1980 and later alternators that strip
BEB that fail on the HDT
heads that crack on the 3B, 2LT
no bottom end oilers in the 2H
bell cranks on the old 40 series
the smaller front diffs on the 90 and later land cruisers
drum brakes on the 73 and older cruisers
clutch fans
the autos in the HJ61s
and of course who can forget the great respect we all have for the elec gauges in our trucks

of course i knew you were kidding but i couldn't pass this up...

LOL. Our Holden V8 do the same thing to fans , must be a family thing:o :D
The clutch fan lets the water pump and water pump bearing live a lot longer as its much kinder to it especially at higher revs.:cheers:

Good point,,,ROTFL... We can criticize the engineers but its probably the bean counters that deserve the kick in the ass.LOL. Stuffed if I could design one anyway, have enough problems keeping it running.$$$$$$$$$$ and more. Perhaps they are all design features and we have not caught on yet...LOL cheers :beer:
 
Good point also....LOL ;)

I gues there is a lot of things that can go wrong out there.... So go prepared with spares. A water pump a fan all depends on the trip. Check things before you go.

Thanks
GB
 
actually you can loosen the fan belt before a water crossing i fyou are worried about the fan going through the rad...
as for the extra wear on the water pump from a fixed fan check out how long the old water pumps lasted with the fixed fans...
check the play each time you change the oil as par tof your rutine...
 
If I was to go with an electric I would wire a redundant hardwire switch anyway, it seems to me the weakest link is the temp sender that trips the relay. Most V8s seem to be running 100a alts. nowadays. However, if we are talking about a 24v system, all your components will be drawing half the amps of a 12V system component, no?

Dave,
what is your take on my experience?

Wayne, you must think the world revolves around you :flipoff2: . I was talking about Ens preference to use solid fan spacers vs. the Aussies experience of using the clutch fan. Are trying to say Ens Industrial is using solid spacers because of you?

Since you think Toyota engineers were such fools, I will send you a spool of wire, some tin and plastic free of charge. Let's see if YOU can make a fuel gauge that works. Post a picture of the results here.

Rosco, you are in Western Australia where you also have a lot of underground mining. What are your mines doing with their 1HZ vehicles?

I dont really no what they use but as the landcruiser's are driven till they will no longer propel themselves ,its unlikly they would get a clutch fan service:D

However I am yet to see a sudden failure of a clutch fan,they are just too damned simple to fail suddenly.

I also cannot see how the non operation of fan clutch would cause overheating at highway speeds as it shuts off at about 30-40kph

nope, i do not think anything revolves around me and for you to say such a thing really shows a lot about you.
i am running the fixed fan because of my experience with one of ENS products, because of THEIR expereince. my personal EXPERIENCE is based on a test i tried and the clutch fan FAILED to do it's job.
now pull you head back out of your ass and take a deep breath and relax.
you do a lot of research and i, for one, appreciate your input but how much hands on experience do you really have? if you go back over many of your posts you assume and congecture much, i on the other hand go by what i have experienced over the years.
cheers and peace bro.

the problem isn't that the clutch fan quites suddenly, if it did then that would be better than it slowly loosing it ability to cool.
if it actually shuts off at 40 k/h as you say then how does it work on hills at speed when it is needed?

The bi metal spring on the front puts pressure on the clutch plate when it heats up from the increase in air temperature from the radiator. When the radiator gets hot the spring expands and starts the fan.cheers
