Is this normal??????

[Don Hiltz]

I have a 2000 Chrysler 300M and a 2004 Hemi Ram. In both vehicles, the heat rises until it reaches operting temperature and the needle stays there, even in stop and go traffic. The fan will come on and go off, but there's no significant change shown in the temperature guage.

In my Viper, the needle stays at the hash mark to the right of 190 degrees. In traffic, it slowly rises until it's almost in the yellow area. The fan starts and it slowly drops back to the right hash mark.

Is it normal for the temperature to flucuate that much????

Thanks....

Don
