V8 radiator on V6 - is this you?

[savage1987]

I need some ideas for options regarding cooling fan and air intake

Currently I am running neither.

VN, VR V6 engine, VL V8 radiator.

nobody?

[savage1987]

OK, set of AU fans being chopped and crammed into place, almost done, and without removing the trans cooler lines from the radiator too!

Still no idea on air intake, will try to knock something up.. maybe a 'custom' chopped up VS SC one.

I heard about this.. Few years ago a mate said he wanted to put a v8 Rad in with a v6 engine. Dont think he did it tho, to much "Hassel"

Keep us updated.. B'coz Im keen to do this myself!

[savage1987]

Oh I've got a V8 rad in it already, had a VL V8 one in since the new motor a few months back. I've had no problems with overheating which is surprising because i've had no fan for the past 10,000km or so..

Fitting the radiator is piss easy man, just do it drops straight in. Not THAT much point to it though, I just love over-engineering things really.

Perhaps for prolonged burnout sessions ? VN-S V8 radiators drop straight into VN-S V6 body's. Only change is the rubber feet have to be moved from the outer holes in the lower radiator support panel to the inner holes on the support panel. Had some M6x1.0x30mm braised onto the header tanks so my electric fan could be bolted back onto the radiator. Inlet and outlets are slightly larger on the V8 radiator. Little bit of vaso and they slide on no worries.

Im with Michelson. Move the grommets to the inner holes dropped the VR V8 radiator in and on with the hoses. Too easy. The V6 fan shroud slotted in the lower clips that the V8 one usually does on the bottom of the radiator. Then i drilled a couple of holes in the top of the shroud to match the position of the screw holes in the top of the radiator and presto. Clipped in the fan wiring plug and all done.

[savage1987]

I won't be running the rubbish V6 thermo any more.. not sure if I moved those grommets either, I can't remember having to. I'm running a VL V8 radiator, pretty sure it just dropped right in. AU thermos will go on soon (almost ready to wire up) and a front-bar CAI if I can find a way around all this custom trans cooler pipework: Seems transmission coolers really are beneficial...

[Michelson4301]

Suppose it wouldn't matter with a VN as their electric fan is only single speed, VR/VS have a two speed fan and really do pull a fair amount of air through.

My VP is only a daily so it doesnt worry me with the standard fan but i can understand why you want something a little better Savage. I think the AU fans need trimming back to fit properly. The Mondeo ones i think are slightly smaller and fit right up apparently. Im on the lookout for some for the VR.

[savage1987]

Yeah my VN is only a daily as well at this stage... but I like knowing I have the best gear I can find for it.. within reason of course. I was going to go turbo 6 but am fast changing my mind to building a stroker 8 for the car myself instead.

The AU fan trimming was pretty basic, I've done just about all the trimming I need to (and yes, it's a fair bit) with just a hack saw. Just need to fix and wire them in now. I got an AU set for just $90 so I used them, after experimenting with an EF $50 set, which didn't seem like they were going to fit at all, ever; those are now on a work mate's VL V8

[Commydoor]

$90 is ok. They seem about that price at all the swap meets ive been to lately. Better than $175-215 on Ebay even if their new. Ive also got a Davies Craig system to trigger the big single ive got off and i cant get it to stop leaking under the hose. When i get my twins i think i'll just wire them up for manual. What do you use to trigger yours off Savage?

[savage1987]

Haven't got that far yet but mine's a V6 which means it's already got the switch mechanism in the ECU.

When we put a set in my mate's VR 215i Senator, we'll have to work out how to set it up properly with an ECU control output..

[savage1987]

Small update:

I got the AU thermos mounted, hooked up and working fine yesterday. They kick in with air con, haven't been able to test with temperature yet.. I used the plug from the old V6 thermo fan, bridged the two earths and the two live from the AU fans into that plug, and upgraded the blade fuse labeled 'eng fan' to the biggest I could find lying around (30A, up from 25A factory). I thought it would just blow on startup but it works OK. They suck a hell of a lot of air through the radiator, even though my shrouding is very hacked up from when I fitted them. Very happy with this mod

[Morton]

AU twins are such a good investment on the V6 engines The standard fan and shroud really suck once summer kicks in. Pics?

[savage1987]

No pics for now, too much fussing around to get them on the computer.. BUT keep hassling me, I'll get some later on
