idle sorted

thanks rubjonny it was the plug behind tb

and i think you were right weazgti the bottom hose gets warm very soon after the engine is started and if i leave the engine idling then the temp eventually rises. can someone tell me were the thermostate is located?
and i sorted the fan as well, the previous owner ran a wire from the ignition strait to the fan so it would come on as soon as the ignition was turned on.
