140 - 160 degree is more common.

You can never replace the impeller too often when you compare the cost of
the item to the alternative!

Thank you Don. I assume you were responding to my engine temperature
question (running 175F~180F with a new 165F thermostat) on a 4.3L single
I/O.

Per your advice I plan to replace the impellor sometime within the next week
or so. ;-)
