Another dumb rad question... dual core???
Thought this was a bit of a dumb question so asked a couple of knowledgeable users off-list and they don't know either so will open myself up to
ridicule? ***
I can guess, but what does dual core actually mean? By which I mean how do I identify a dual core rad?
Does it mean that there are two pipes running parallel to each other (one behind the other with rad in place on car)? Or does it mean something
else?
If it's the case that there are two pipes running parallel to each other...
...does the Polo rad have this? Is it dual core?
I'm basically only curious as a Polo is clearly good enough for my Pinto!!! But I'm interested for the big power boys. (and also an
argument I was having with my Dad about air flow! )
Cheers,
James

if the same terms that are used for Land Rover radiators, then you are right. It is the number of "tubes" running vertically dwon when
counted from the front. Thye may be behind one antoher or staggered.
By removing the radiator cap, you can see the cores, well you can on a LR one , otherwise you need to look at the cores themselves and maybe use a
wire to poke genlty around.
ther is more to radiator design and cooling than just cores - depends on what the question you disagreed on was.

James, see PPC mag this month. Good article on rads. They reckon single core al. rads are best. Also interesting is that rads. work best at 20degree
inclination due to airflow hitting the tubes rather than the fins. Question now is do I re-site mine? Saw on a thread that a Polo al. rad will cope
with c.200bhp cooling.
Cheers, Pewe

That's exactly right James.
My polo rad is vertical, and will hopefully cope with 200hp!
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

Ok, cool (no pun intended).
Thanks everyone!
So, question is... is a regular motor factor Polo rad a dual core?
Cheers,
James

No, as the al. conducts heat far better than copper so except in race sit. doesn't need to be double. Cheers, Pewe

I would need to look it up but I don't think there is that much difference in thermal conductivity; the reason I've seen given for using
aluminium is that the cores can be made bigger.

Interesting about the 20 degree figure, I was going to mount mine anyway I could in the nose but maybe I'll put a bit more thought into it now
Cheers
