I agree with allan and Greg.  I have used my old 1200 D 4x4 /345 PU out
spraying weeds on farm and range land.  105 derees F. + for up to 2 hours,
then to the next place, and to let it idle was not a problem.  No
overheating, but that was a manual transmission, and a factory SHROUD.  I've
always had more problems with overheating at load and speed than idling.
The same heating and cooling applies with the 1310 4x4 PU with A/C  and
manual trans. We can get into the 110 temps in the summer up here, but
unlike the south it cools at night.  Jim A.
