Got a new alloy ebay job radiator. The original radiator was hard mounted against the radiator support panel. Must I use rubber bushing bolts on the new aluminum radiator?

Must you use = no
Should you use = yes.
Electrolysis will destroy your radiator if you hard mount it, also vibration is a big killer of aluminum radiators.
A soft mount absorbs vibration and greatly reduces electrolysis. 2 birds with 1 stone.
Or you can hard mount like your copper core radiator and disregard anything i just typed.
Should you use = yes.

Thats pretty much the straight up answer I needed. Thanks. What about intercoolers?

If I were to 'soft mount' a generic alloy radiator, what hardware should I use?
Just a rubber grommet with a big washer and a bolt through it?

I can't really see how that kit would work, unless one of those nylon bushes slides inside the other, how would they prevent the radiator coming into contact with the bolt?

Maybe it doesn't matter if they come in contact with the bolt and it isolates the bolt from the support panel. Will let you know when they arrive.

mines hard mounted, its polished and does not show any signs of electrolysis or cracking etc.
shouldn't a good coolant stop any corrosion inside etc, hard mount will give u more clearance between fans and engine if needed

Had mine hard mounted for 10 years now. Haven't had any of the issues stated above? I had always wondered if that was true or a myth. Done 3 other cars the same. Hard mounted and no issues

Intercoolers do not have water flowing through them that is attached to an engine block that changes current all the time. So meh, I still would though.

THat is literally how I mounted the rad in the LJ, just take the holes out a touch more, rubber grommet, bolt it up. Literally to cheap and easy to not bother IMO.

Go kart shops usually stock nice looking rubber bushings & bolts. That's what ive used in my modified torana days, some friends were right into karts & had plenty of them, i would use the rubber myself.

So the bolts pictured by Bigfella are 'well nuts'. They expand when tightened. They include a spacer which also helps insulate and moves the radiator away from the support panel.
Otherwise I'm told these are popular from repco. They get used for radiators and fuel pumps to eliminate vibration:

I just wouldn't F#$ken worry about it - there only 160 bucks, - if your running a romac balancer then you need all the clearance, also the bottom of the radiator will hit the skirt and you may need some off set bushes unless you raise the radiator - it's a balancing act.
just remember - don't spend more that 160 bucks
