Outer Limits 4x4 Board

how legal is a tray mounted radiator in vic and does any body have any tips on how to do it? My 4x4 has already been engineered and is not a daily driver

dont know about the legalities but,i used a ford AU radiator &
its factory thermofan/shroud setup..bent up elbows,& baught
extra heavy-dute radiator hose by the meter,just chech your
pressure,because you might even get away without using
an additional in line water pump,I didnt need one
(not yet anyway)theres pics of it in THE DIRTCOMP mag
on piglet

Is there any problem (other than water pressure) with mounting it up so high or on an angle?

sofar all is good,have done a lot of long distance hwy work
in it,longdistance high speed sand(at OBC) & slow tight winch
challenge stages,probably drive it out to Tamworth,for rnd3
extreme winch in oct,im running V6 comy,37"tyres on a
feroza ute,& the radiator seems good,sits around norm temp

I just had a length of exhaust tube bent to run most of the way from the front to the rear. Then just got some hoses and cut them to suit regarding bends etc. No extra pump needed.

Only draw back with the way mine is mounted is 100% of cooling is done via the fans, it gets NO air flow even at 110km/hr on the highway. I am going to move mine when I get around to it and mount it under my spare wheel rather then hard up behind the cab.

Drop buy, I have a couple we are building ATM with that setup.

i cant see why it would be illegal

I did the same on my Hilux with a 2poofty3.

Just a thought. Would a wide-mouthed snorkel type setup help to direct air through your radiator?

Yeah it would, man how cool would it look, might put 2 of them on my roll bar and then get a pair of stacks to compliement them

I'm mounting mine with the top of the radiator away from the cab and the bottom closer and putting a scoop on rear roof radius to drag air down into the radiator.

Not needed, just mount it with top of radiator laying forward and the air will come UP threw it without doing anything else. The way your talking about will have 2 different air flows fighting with each other.

Mine only gets no air flow because it is basicly hard up beind the cab (about 100mm off it)

guts do you have any troubles with over heating though?

NOPE, none at all, doesn't matter how hard or for how long it cops it and never gets hot, even on 40deg days .

ATM only 1 of the fans is working and it still doesn't get hot, would if it was a 40deg day.

The ONLY dissadvantage of all its cooling being done via the fans is power usage and this is the main reason I am going to move it. Well that and it will look heeps better being hidden with the spare wheel mounted over the top of it. IMHO it looks crap where it is atm.

Best thing was even after the bog hole in the vid it still didn't over heat as the radiator stayed 100% clean and out of the crap If you listen you'll here me say 80. Oh and the smoke is from a cooked power steering

That sound really good got a nice note to it

it depends on your engineer.

mine is OK with moving the radiator to behind the cab, but i have to do cooling tests to satisfy him that the car will remain at the correct temp when driving on the highway.

i've gone for a late model falcon radiator with a factory twin thermo, as well as an auxillary water pump.

i'm only trying to cool a 1.6L though.

And a few spare aeriels and marker lights like this bloke (not one wire running to 6 aeriels)

on the legal side, in queensland it is perfectly legal, aslong as there is no way of boiling water entering cab. thats from a mad plater and an engineer.

my VASS engineer is happy with a rear radiator provided i can guard it to protect bystanders/idiots from injuring themselves on fans etc or getting burned by touching the rad. i also have to protect them from the event of the rad cap releasing, spewing superheated coolant on their pretty little faces.

heres how mine is goin to be mounted behind the cab its a late model falcon radiator and i have standard thermos to go with it aswell i still need to do the piping but hopefully it shoudl be fine

looks like you have enough space to lie it down flat
with fans above,,put an access floor out of mesh above it
then you have an area for recovery boxes or storage
I only wish ihad that much space to play with

thats looks like its going to heat up your lpg tank nicely, the fans pump out a massive amount of heat, be carefull

Yep, Rob (bourbon) used to have the problem of boiling this fuel in his buggy as the fans used to blow straight on to the tank.
Mine atm blows straight on to my batteries which I don't think would be the best for them either, another reason why I am going to move the rad.
