Car Temp moves from 80c to 100c then the fan kicks on?
 

The 2001 CL 500 seems to be running very hot? Not 100% sure, but I have had this vehicle for a fews years and I usually remember the temp staying right above 80c? If I am at a light or in traffic the temp runs up to and over 100-120c and the fan kicks on because its getting hot. It never even gets close to the red area which is good, but I am just wondering what would cause this... Do I need a coolant change or something? Someone told me it could be a bad Water Pump?


Thank You for your help
