which radiators should work better, new or old?
ok, since i am always being different, and since my exhaust runs down the centre of my bay kombi, i cannot fit my radiator where i wanted to in the
middle of the chassis like other bay kombi subi conversions. as an alternative i am planning to run 2 small rads, one on either side of the main
chassis rails, betwen the rail and the edge of the body (see dodgy paint diagram). i have been scouring wrecking yards for radiators and have found 3
options, my question is which will be the most effective radiator? the first is what i believe will be the worst, the thin and flimsy looking
radiators from the diahatsu miras and similar, which are the perfect dimensions, but about 1/2 the thickness of a standard radiator. the size would
seem an advantage to me but i cant imagine the thin little rads would cope. the next 2 are the ones i am tosing up between. there are the radiators
out of the suzuki swifts/holden barinas that are also the perfect width but have a more normal thickness, i assume these will be better then the super
thin diahatsus? and then i found the rads in the old austin freeways, they are super thick, are already setup on the side of the engine bay with an
enclosed fan attached to them, they draw through a louvre on the body and have fins that are super close together, the only downside is that they are
an inch too wide. in my mind these would be the best, but what do you think? should the newer ones be as good? or better then the almost purpose
built older ones?

The older radiators would be copper and the new ones aluminium with plastic tanks. Maybe?
One of the reasons radiators are thinner these days is the material and fin design is much more efficient, and they are able to make them thinner.

cool, thats about what i thought, the main temptation of the austin ones was that they were setup for a very similar application to what i had
planned.

got a pair of swift ones, fit nicely, and after taking a bit of a look i reckon i will get better air flow on these side ones then on 1 central one,
as i can use the outer side as well as the rear to let the air out.
