bad idle or overheating after stopping?

Try running without the under engine plastic tray.

I removed mine years ago mainly to aid the view of any liquid leaks.

I understand it was fitted for something to do with high speed running. As I rarely exceed the NLS by much for any length of time I have not had any problems.

Without it it would allow the air from the rads escape.

Problem is that hot air rises. So when the car is parked, hot air will always travel to the bonnet and not to the underneath of the engine bay,
You may get a little more cooler air depending whether it's windy outside when parked up.

But it would help to draw in more cool air from below and reduce the air temp above the engine.

Hardly, as the air has limited way of escaping there will be no significant flow unfortunately.

Had to get my science book out for that one

Fascinating ... maybe discrete slits in bonnet plus removal of a tray I never even knew was there ... I am shocked I spent six two on a two six and never even bothered looking underneath the thing :-/

Ah, but that's how hurricanes are formed cool air meeting hot air.

...... After 10 mins driving and stays there, no matter what ..... after 570 miles in three days , 460 of them in 24 hours, I wonder is the needle stuck or is my cooling system really neat?

Needle stays round the middle between 75 and ~100 degrees or so.(someone will correct if wrong)
Done not to alarm the driver when temperature fluctuates

It's not a real representation of the actual temperature

I have had this problem bad since I bought mine. Last week, changed all the spark plugs for the NGK recomended upgrade, which handle the temperature better apparently. (Bought them a while back as part of the Terminator SC upgrade which I STILL haven't got round to!!!!) So far been running great, but no sunny hot days as yet to test it.

I have also got a marine 100mm duct fan to install, to draw cooler air from below the belly pan up to the top, and I intend to put vents in the bonnet during the SC install.
