cheers,
ian

ok cool im not wanting to get a custom rad made if i can help it, thanks tho.

Why not get a custom one?? ... there is a Tripple core available for the MY models and also there is 2 different size top and bottom brackets.... if you can find the larger ones then u can end up with a tripple core radiator with the largest available radiator fitting in the normal spot... with no body mods.

I don't beilve an EJ one can be wedged in there without some major work.

yea ok, i wasnt aware there was a 3 core one available for the ea's, SWK said that i have to cut the bottom out of the support pannel and weld in some angle bar and weld the mounts for the ej rad to sit in, but if theres a 3 core available ill just get it and get the bigger outlets welded on

I just used a EA dual core and got the outlets modded to fit with 90 degree angles. Seems to work perfectly fine, and I know of a few others who swear the EA dual core is more then enough for an N/A EJ.

But if you want to spend money, a 3 core custom sounds great.

well i have a custom dual core rad, with brass jackaroo end tanks..works soo well. Keeps my ej22 real cold with just one 12inch davies craig fan..

take sum photos for u tomorrow..

I only went tripple core cos i wanted to know i went with the best i could find.... im sure a double core would be fine... even a single core i belive would have no problems if in good condition.

My knowledge of the mountings only extends as far as L series, MY is abit different from what i gather.
In my opinion it's a better option to get a custom radiator made up to fit the standard mounts rather than extensively modify your lower radiator support. Couple of reasons..
- You get a brand new radiator (who knows, the EJ one you use may need a re-core soon anyway).
- It's easier. Just buy it then plonk it in. The radiator guys are the ones who have to mess around.
- In the event of maybe one day transplanting everything into another car body (maybe yours gets too rusty or rear ended or something) then theres no need to re-do all the custom mods.

fyi - don't forget you will need to factor the cost of a couple of electric thermo fans into your costs. They aren't usually too cheap and it sometimes gets overlooked (the EJ ones won't fit, they are too thick).

hope this helps!

You make good points there, ill look into a custom alloy one(oooo shiney) and yea i was planing to find a few 626 a/c fans at the wreckers like Phizinza did.

hehe Shiny is always good, although I've heard they are difficult for radiator places to repair in the event of a crack or split.
Mine's a Liberty core with Holden Gemini brass end tanks. Easy to solder up to repair it one day.

With the fans I probably should have looked into getting some secondhand fans off some other model of car but I ended up buying some Davies Craig fans. They are very very thin profile so they fit well between the radiator and motor. Waggaclint recently came accross a cheaper brand which claims to be better on an Ebay shop too.

Hmmm interesting, what are the davies craig fans worth roughly? they were a pit pricy last time i checked

Just some radiator facts to throw around .

Aluminium cores cool far better than brass/copper in this application . People always claim that copper is a better conductor of heat than aluminium which is true but - always the but - it the method of holding it all together that kills their efficiency . Copper/brass rads are stuck together with solder meaning gills to the tubes and tubes to the cores end plates . Solder has a very high lead content and lead is a very poor conductor so heat transfer from the gills to the tubes is not what it could be . Aluminium cores a furnace brazed so head transfer properties are far better . Your typical late type radiator also weighs ~ 1/4 to 1/3 of the older type which is valuable to me anyway . My only problem with late type rads is the plastic tanks which can fail after thousands of heating/cooling cycles when getting old .

Elec Fans . Manditory on east west engine because the crank faces the wrong way . Some people go out of their way to toss the engine driven fan for electrics and I think is a bad call because :

With the "part time" fans you have no reserve of cool water in the rad for the engine to call upon when the thermostat opens right up . What happens is the engine starts to get hot under load - thermostat then opens and the rad temp goes up with the engine temp . Elec fans are usually set to come in reasonably high so the whole cooling system is getting up there before the fans do anything . When they do switch on they dump all that heat into the engine bay so its temperature goes up as well . Far better to leave the std engine driven fan and if really necessary add the elec fan that A/C cars have .

Your call .

Note - Brumby boy is doing an EJ engine conversion....the EJ engines use two electric thermo fans only by default (both controlled by the engine ECU) - they never had an engine driven fan. (that being said I love the old EA engine driven fans, they do blow a gail!)

The Davies Craig 12" ones are about $160 each from most retailers. Two of these cool an EJ very well.

yea id can the engine driven fan if i had one on the EJ, personaly i think they look out of place (read UGLY) and replace it with one full time fan and one part time (ecu controled fan) but because the ej does only come with electric fans i will be using two electric fans anyway, however i am yet to decide weather or not to have one hooked up full time or splice both fans together as my harness only has one fan plug in it.

$160 bucks thats cheap to me, last i checked they were bit over 200
