A question for the fellas with aftermarket turbos and especially the fellas who've done the v8 conversion into their hiluxs. What radiators are you guys running in there? I've got the 2.8D with a CT20 running around 10psi. Occasionally it gets hot especially running up long steep highway hills on hot days. I'd prefer to keep the temps down and under control.

What kind of aftermarket radiators, or mods have you guys done to keep the temps down? and also wherabouts can i get one in Brisbane or SE Qld

Just put a dts kit on mates and fitted new radiator at same time (stuffed old one a week prior) he hasn't had no problems yet also have anoter mate runnig dts kit and hasn't had a drama with it might be tine to get the cores flushed or maybe the fins betwwen coresare falling apart/stuffed also do you do alot of mud driving my mate found with his it all looked clean but there was a layer of mud between A/C radiator and main Radiator it got hot going up cunninghams gap that was all. If you wanted to run a after market one i think PWR make them available through repco and prob other places

anyone else? What about you fellas with the v8's? I'll have a look into the pwr's are they aluminium or still copper?

copper 4 core.

I didn't say it was a PWR

Original Holden V8 radiator mounted on the back with twin thermo's.

where do you get a copper 4 core from? What kinda cars are they out of? Much work to fab em up to fit?

in my 75 ive fitted the originial diesel radiator with the marks clutch fan adapter kit to suit the holden v8 and just made up my own fan showd and its hasnt over heated yet

Some thing a bit random but mates ran a forklift radiator in holden inline 6 corona mounted where passanger seat was with twin thermos on it in a bunout car sat on 5500rpm for around 4+ min and didn't even look like getting hot also was a mad rally/bush basher

I run a custom jobbie in my Surf.
Its a 4 core copper with Toyota top & bottom tanks and the hoses have been swapped around to suit the 5ltr .
I run a steel VK commodore fan with a 14" thermo (set up as a push through)
I use the car every day towing a trailer and the temp sits between 85 - 95 deg all day every day, no matter what type of driving, on & off road I do the temp stays in this region. Even on the last couple of 38+ days we had the hottest I got was 100 deg sitting in stopped traffic and when we started to move it dropped to 90 deg asap .
I've been running this setup for over 2 years now.

Whoops double post

I'm just running a taller and slightly thicker copper core with my Lexus V8. The core is supposedly meant for a surf (don't know what one) bit with the 2" bodylift it fits great, and keeps the V8 cool just about all conditions. The only time it hasn't worked was trip to Fraser for New years. Had the 4runner fully loaded, with also a fully loaded trailer on the back and it couldn't cope doing a high tide run up the beach. But loose the load, and it's fine.

Heres a pic. New radiator on the left, old one on the right.

I use the standard Hilux LN106 diesel radiator with this fan

So you're not sure where that core's from? It looks almost factory hey. Are you going to make up a shroud for it? I reckon that'd keep her real sweet then.

Nah, the only "surf" I can think it would be for is the later 96+ models. Nambour Radiators done it for me but, so they could order one in if needed.

I don't have room for the fan to be on the engine side of the radiator, so the fan is on front of it. Hence the no shroud. But I wanna looking into recessing the radiator into the support panel and trying to fit the dual AU fans on the back side of it. And also maybe look into making it a dual pass radiator.

A good mate of mine did Twistys radiator, i'm sure he said it was a 3 litre turbo surf.

i have a 2.8 with aftermarket turbo and still run standard radiator
i used t geet hot when i first put it on but i changed the thermo stat and got the radiator flushed and now it doesnt go past half way even on a hot day with air con on going up a hill

I've done all that to my rad and put a factory thermo in it a few weekends ago. Just wanted to see what the big boys with their 1uz's were doing. Would be nice to not worry about it heating at all even on the worst hottest days

i'm using the VK V8 rad in mine with the 5ltr and twin 10 inch thermo's fabed some lower mount and modded top mounts from a VR comm so no mods to the rad to make it fit buy one of the shelf and put it in

When I fitted the commodore V6 to mine I used the WB Holden three core V8 radiator and twin thermos from an EF Falcon. Just had to do up some mounts for the radiator to the body. Worked well for what I did with it.
