Sorry I meant the temp. gets to normal operating temp. and had been running for 15-20 min and it's still cool in the car. My Olds Intrigue is warm within that time period and are most cars I think. When it's idling after the engine has warmed up, the temp gauge gets pretty close to the red and then the cooling fan starts to kick in, but stays close to the red. Then I start driving and the temp gauge goes down right away.
