Upgraded radiator with 3 inline tubes and large V shape fins, as used by some Cooper S Historic racers. No drain hole or facility for fan switch.
Has 7 V shape or 14 fins/gills.
C-ARA4442 (2 core) has 12 per inch.
This has 3 large oval shape in line tubes whereas the standard
ARP2000 has 3 offset tubes.
More espensive to produce than the 2 core but slightly better overall with same top tank as all our special radiators. On the road seems equal to our 2 core type but seems to have a better heat dispensation when engine is turned off, or idling by not boiling over, or loosing water and holding pressue when used with 15lb rad cap.
The fins allow more air through when stationary.
As used by Peter Baldwin the Mini Miglia champion and other Historic drivers.
Not suitable for grasstrack or Autocross as any heavy deluge of mud or muck could block or damage the large V shaped fins in the core.
The 2 piece radiator cowling fitted to Cooper and S is avaialbe as
ARA2770 and this rad fits Mk1/2 engine bay perfectly.
If your engine still overheats check the water pump for cavitation as caused on non genuine pumps and always fit an electric fan if engine is well tuned.
If you have the radiator out it makes sence to change to an evolution type lightweight water pump
GWP187[/link with 3 year warranty and new fan belt of course. If you have a by pass hose see [link]GWP134
