Success,
the two core radiator along with the genuine Subaru coolant (recommended by Paul) has nailed the overheating problem, also had the twin Davis craig thermos mounted on a bracket in front of the radiator pushing in.
I was heading back from the beach at Wagoe on a 36 degree day and a mild tail wind in fairly soft sand for 8km's and my gauge went up to a maximum of 95 degrees (yeee haaaa).
That's one problem solved now, time to concentrate on other issues now, like front shocks (

Other additions to be completed within that time include an under bonnet ARB Compressor with bull bar fittings

Have just fitted the second light bar, a ridge rider roof basket and hard wired my dual battery (ArkPak 715
http://www.arkcorp.com.au/p/3231/arkpak-715 ) with a 105ah AGM battery, dc to dc charger) and dual isolated led battery monitors.
Should be a weapon when finished.
Two core installed.
Roof Basket
Twin Led Light bars with upgraded led indicators / parkers
Loaded ready to go Fishing / Camping
