Normal engine water temperature for a D-60, 2000 lxi???

[David Brady]

If the ambient temp is below 90deg F, mine runs at 190 or below,
whether cruising flat level ground or climbing mountain grades; i.e,
turbo pyrometer reading 950deg F for an extended period of time.

When ambient is above 90 deg, she reads 190 on flat and level and
200 to 205 when climbing grades.

In Arizona on a 110 deg day, and while climbing, she may get
to 208 deg F, at which point I back off, downshift, and keep the revs
up. Never goes above 208, probably mostly due to my driving style.
In hot weather, she does need to be managed a bit. This is why many
of the coach operators run water misters on their radiators.

When I was at the Detroit Diesel dealer they said the motor will shutdown
if temps go above 220. But that's with the DDEC II electronic engine
control/software. I also learned that my dash gauges reads 5deg high.
