Actually it is a valid comparison. Everything is bigger and thats about it. New trucks dont to a million km without a rebuild yet i know of cars with a million km still going strong, my old landrover was never rebuilt and all original including alternator with 540,000km. As for the 26si, thats a brushless alternator so it should pretty much never fail. An electric motor is an electric motor, there are better and worse quality ones......

how often has a electric fan failed on the many cars i have owned in many years? ZERO is the number, how many times has a clutch fan failed? quite a few, now there is air operated fans that are prone to leak.

wait WHAT? are you kidding me? it takes 25 amps, does 10,000cfm which is about right, my 2000cfm fan on my car has a 10 amp fuse at 12v.

mine was shocking thus spent a few weeks replacing all push on fittings with compression ones plus all joiners removed and new lines run. I just got the price on the electric fan and lets just say im going to rebuild my air clutch

nobody will give you factory specs and im not entirely sure they bothered to test them, but the 10,000cfm fan is overkill for sure as system tested on a baja truck in the desert

Sorry i ment cca not ah, my bad. As for the electric fan it will power on as required and takes 25amps at 24volts while my alternator is 100amps at 24 volts therefore ample headroom, it wont run 100% of the time and will be actuated by the same computer signal the horton fan was actuated by but rather then pneumatic it will be electric. Mainstream manufacturers do what is cheap not what is best, its about providing a product just good enough to pass the warranty period at minimum cost, a clutch fan is much cheaper to make.

I understand nothing is free, and yes it goes at a single speed irrespective of the engine or alternator output..... thing is i have four 920ah batteries so that will buffer it. As for the electric fan failing, i know it can happen but these fans are made in usa and brushes are easily replaceable while its on the truck and short of that nothing really can go wrong unless i abuse it (which i wont). Reason im looking this way is that i believe i have a horton air operated clutch and it needs a seal kit put through it as is leaking, i cannot understand how it can be 100% leak proof as its a rotating assembly so it must leak by its nature and i hate air leaks.

when a new plastic tank is 300 bucks........ i figured id try.

Update: one radiator hose was recoverable, rest were too close to failure so replacement, given the amount of crud i found in the system i am tomorrow taking the radiator into a radiator specialist and most likely going to rebuild it with new core and while im at it will add a few more cores as my view is can never have too much cooling capacity. Also noticed the truck has a pneumatically activated radiator fan.......... so looking into converting to a 24v electric fan, not a fan of engine driven fans, they rob power, prone to failure and never had an electric one fail in any application yet. Found one that does 10,000cfm which i suspect is ample for the application, waiting on the company to get back to me, their made in USA....... mob is called "electric fan engineering" image of a comparison to a standard thermo fan

On a really rusty looking coolant reservoir/ plastic overflow bottle i used the following: vinager, bleech, CLR (worst crap ive ever used i must note), boiling water, dish washing detergent, and baking soda two types of laundry powder and can report vinegar was the best, CLR was by far the worst and im pretty sure boiling water did more. Trick i found was to use cat littler (non clumping type) into to container an shake it about which did losen the crud quite a bit but 30 flushes and about 6 hours and i must say ive only got to the point i can make out the water level without taking the cap off............win? Not sure.

Progress is slow but stainless pipe really does bling it up a bit (its black ceramic coated on the end as muffler place could not get a stainless end but i think it looks cool)

I got it done by a local turbo rebuilder, very reputable company and excellent reputation. Been around for donkeys years so fingers crossed. Not a chain but a family business.

my understanding too, to be honest i hope it does something for the temps but mainly im a stickler and i hate rust

correct

not temp resistant paint brother, its all black ceramic coating
