As i said a few years ago i fitted two (2) 12'' pusher fans on the trans coolers i have in front of the radiator which i have thematically controlled and also have a manual override switch, these fans do add some cooling to the radiator in the slow traffic movement via the manual switch.
So yes what you are saying will work okay.
These are the two 12'' pusher fan i have fitted to the trans cooler and water to oil coolers
Thanks Blue.
I will let you all know how I get on once I get the project under way.
The main aim with the electrics was to get air movement
when idleing in city traffic, keeps the air conditioner happening.
As I said I can easily refit the standard fan if the electrics
dont cut it.
I can still use the electrics elsewhere so I have not wasted
too much cash.
I like to tinker and experiment with things, always have, and it's
how I have learned most of what I know.
Sometimes this is disasterous but fortunatley not often.
Learning the theory is good, I have not objection to book
learning at all but there is no substitute for hands on.
By all means go ahead, will happily follow, just wanted to make sure you are aware of the potential pitfalls.
If one of your concerns is the A/C in city traffic, have you already done the change which turns off your heater 100%? I can't recall the process, but it substantially improves A/C performance.
Thanks Blue.

When i fitted the trans coolers i had a AC guy fit a sender in the top AC line, so when the AC was not cooling to good it would switch the 12'' pushers fans on and blow through the trans coolers and onto the air condenser and help cool down the AC air flow, this could assist you with what your trying to achieve.
Just a thought mate.

Thanks for the tip and yes I have done the mod to fix the heater
always on stupidity.
I am once again amazed at the stupidity of whoever thought that
was a good idea.

I did something similar to the Landcruiser as it was not keeping me cool
in city traffic durring Adelaide 30+ degree heat.
I tapped into the power line to the aircon compressor and used that to
trigger a relay that turns on two 10" fans, pushing in from the front.
Basically whenever the aircon is on the fans are running.
It works well and has been doing it's job for close to five years without
a problem.
Thanks again to both of you for your advice, I will keep you posted on
how my fan replacement project goes.
Made up a replacement shroud / mounting frame for the two 14" fans.
A sheet of 1.6mm aluminum and a 25mm aluminium square tube frame.
Added some 25mm x 3mm aluminium flat bar to brace the sheet and
give the fans something more substantial to bolt into.
Engine side view.
Radiator side view.
With fans and relays mounted.
Still have to make up and attach mounting brackets and I will be puting a 24mm x 6mm strip of adhesive backed polyehylene foam tape on the
radiator side of the frame to seal it against the radiator.
You could put little hinges doors on the non fan areas. So when you drive along they allow the air flow and swing backwards, but when the fan is on they create a negative pressure area and suck closed to allow full flow through the radiator and out the back of the fans
Yes, finally got time to finish all the jobs I started.
Still got a couple of minor gremlins to track down though.
The fuel gage is stuck on full, some electrical problem to
chase.
The battery warning light stays on, even though the batteries
are fine and the alternator is puting out plenty, it's keeping the
starting batteries charged as well as the two deep-cycle GELs
in the back running the fridge.
I did some night driving with high beam and the two 100W QIs
on without any problems.
Another electrical fault to track down.
I also have a slight coolant leak, somewhere in the heater
hose I suspect.
All in all they are minor problems that I hope should not be
too difficult to fix.
I have just driven from Adelaide to Catherine Hill Bay, near
Swansea in NSW, fully loaded with the caravan in tow.
The truck performed well the whole trip, with the exception
of a bit of over heating in the tranny while crawling through
Sydney. The tranny overhaul is the next thing to deal with.
This is the first long trip I have done since I bought the truck
and am quite impressed, a much more comfortable and quicker
run than it ever was with the Landcruiser.

Check the float, often the cause is that it is stuck on wires in the tank from on the fuel sending unit. Zip tieing them out of the way is a permanent fix.

are fine and the alternator is puting out plenty, it's keeping the
starting batteries charged as well as the two deep-cycle GELs

Check the grounds and battery connections and clean them. Otherwise it is probably the voltage regulator . The diodes can go bad in them, it will still put out the right voltage, but slightly less current.

Glad to hear you had a great trip.
Speak to Rod at Alcorn automotive if you need a transmission build.
Adrian,
Many thanks for the tips.
I think I have solved the coolant leak, one of the hose clips on the bottom
radiator hose was a bit loose. Gave it a couple of turns and it seems to have
fixed that.
