Most miles before engine rebuild/replacement

[Don Bradner]

Sounds like your fan does not come on automatically. Don't know if you have an
alarmstat, but if you do, it is probably bad.

With the Aux fan on manually, my engine runs in the low 180s (180 degree
thermostat). If I have manual fan off, it comes on at 196 and off at 190, and
will show a range of 189 to 197 (overshoot, presumably). Since the climb from
189 to 197 is steady, I can imagine hitting 225 sooner or later if the fan did
not come on.
