This is probably normal. The fans are not programmed co come on until about 227 degrees. That ma seem high but it's normal.

Thanks for the information. Good places to start. Followup questions though..
- every other car I've seen once the car is up to operating temp the gauge doesn't move. Would it be normal for the gauge in the aztek to fluctuate between less than half and nearly overheating on a consistent basis.
- in the aztek what temperature do the notches on the gauge reference? Or is it arbitrary?
- is there a way to measure the engine temperature? Like with an infrared thermometer or something to that effect.

Thanks again and in advance.

The dash gauge is not real reliable but the fluctuation could also mean air pockets in the system. The best way is to use a scan tool and see the exact digital temp that the computer is seeing and verify that with an infrared thermometer.
