Shortly after I got my 00 XJ I noticed my engine temp was running colder than usual. It usually runs at 210-220. So I popped the thermostat housing off and my thermost had actually broken apart so it was never closing. I put a new one in and everything was back to normal.

Mine was running 210-220 until I replaced the water pump and flushed the system out. I added 50/50 mix and after that it always runs 190-200 on average, occasionally 215ish.
