I just put in a 180 myself and now find my 2000 XJ running about 200 steady.

OEM is a 195 therm at 210. Sounds like you need a coolant flush and check to make sure your electric fan is comming on.

Before the 180 stat I was running to cool but now it stays at the 210ish mark.
When should the elictric fan kick in?
