[urq] Dialynx rad vs Stock rad w/ Aux rad delete

[SpotatAshleys]

Mauritz
when I rebuilt my car and engine I replaced the stock radiator set up with a
coupe/coupe quattro rad which I had re-cored with a 5 core matrix (standard
was 2 core) and deleted the auxillary rad.
Been running with this for 2 1/2 years in all weather with no problems at
all. In fact I reckon deleting the aux rad actually lets more cool air in to
the engine bay.
Having the coupe rad re-cored with the most cores you can will be fine and
probably about 1/2 price of a Dialynx rad - although I do believe the
Dialynx rad is good.

> Recently my main rad has gone bad (amongst other things) and needs to be
replaced. The aux rad was deleted a long time ago (also leaked) and never
noticed increasing water/engine temps, not even during high speed travelling
in summer. Although I have to say during this hot summer my exhaust manifold
cracked at several places, but that's just coincidence :-)

turbo.

the exhaust manifold is replaced with the performance Dialynx EM? More

do have a good stock 48cm main rad from a CoupeQ but it lacks the extra aux
rad header. I've read in the archives a few people had no problems what so
ever removing their aux rad while keeping the stock rad.

If the aux rad could be removed while keeping the stock rad, this would be a
major cost-saver.
