what savant said :P

when you stop and start the engine heats up becasue the radiator isnt getting air blown into it to cool the water/engine etc...
when you drive long stretches and faster nore air flow cools the engine'



my temp guage never really gets over a 1/3 even in traffic its mostly down at zero :P
