Outer Limits 4x4 Board

hey ya'll. have an RN lux with a holden 253, dual fuel gas and petrol. damm thing gets so friggin hot....

changed radiator with a 3 core radiator, installed massive thermo fans... even today i removed the BONNET and went for a bash...

still gets relatively warm. tried removing and now replaced with a new thermostat.

thing is... its fine whilst driving on road, as soon as I stop at lights or go offroad it wants to overheat.

suggestions, queries, comments??

do you have any pics of your setup..

Has this just started to happen , or its a new setup ????
some things to check -

* Try flushing your radiator and engine block.

* Try without a thermostat

* If using a thermostat what temperture thermostat are you using , try maybe a colder one.

* Is the water pump ok ?

* Is the speed of the water pump quick enough whilst idling or running at low rpm's to circulate the water through radiator, maybe the wrong pulley is being used ?

* Are you running to lean ?

* Is your timing way to advanced ?

* Has the conversion been done properly regarding that the fan is in the centre of the radiator not to high or low ?

* Have you got a fan shroud , if not get one they help a lot !!

Hope this helps.

Cheers
