[360]

Had almost the same exact issues that Adrian is experiencing on my maiden voyage back home yesterday. Was 90+ degrees yesterday in LA when we left and a couple hours into my trip when I got to feeling a little more comfortable I took a good look at the gen gauges as we were running the generator to power the roof A/C and noticed the temp on the gauge showed 235 or so. Pulled off and checked to make sure fluid coolant was not low and it took maybe 1/3 of a gallon max. Didn't have a digital temp yet so stopped off to get one of those and checked both temp on the fins of radiator at which I get readings on the right side ranging from 210-200 and on left side from 120-160. Thermostat housing reads 219 when analog gauge on dash reads just shy of 250.

I shut the gen down and sweat us out for a couple of hours and then fired it up a little later in the day. As the ambient temp came down so did the gen temp to where from 9pm on where temp as 75 gauge on dash ran right around 180. So I'm assuming from Gordon's post that was probably closer to 150's since my gauge is clearly off by about 30 degrees.

One other thing Steve recommended since the temp was so different from one side to the other was I pulled the cap when running and the coolant inside was not moving. Sounds like there may be some kind of blockage so I'm going to have the radiator rodded and see if that helps along with a digital temp gauge so that I can see accurate gen temp.
