On my zetec temeperature is always right on M all the time, and it does not veer higher even in high heat/ac on or idling for long time. I was just curious what is the significance. Zetecs always feel like they are running very hot becasue of the darn cat that is practically bolted right under the hood. It radiates a lot of heat felt when one opens the hood, but it is not the engine heat, just a cat.
