    Just installed a temperature gauge, sender in the stock location in the block, driver's side, and she's running right about 200*, at least according to the gauge. Is that good, bad, ugly?

    Normal operating temp is around 190 F. Point is, you want it to stay there when you start working it.

    Yeah, she seemed to stay right there even at highway speeds and banging on it ... well, as much banging on a 6.2 with 3.08:1's as one can do :rolleyes:

    That one, I think. Cheap, simple.

    Sorry for the crappy pic, flash in the dark. Anyway, the CUCV has the idiot light dash, i.e. no gauges, but I am too cheap and lazy to change the thing out ... I'm "keeping it original", yeah, that's it. :rolleyes: But after toasting the motor in one of my other rigs, I wanted to keep an eye on this one, especially as I *fear* what replacing that 6.2 would cost... so this was cheap insurance.

    If I remember right, the thermostat available at parts stores is a 190* or a 195* thermostat. On the 2 diesels I have driven (still own and drive one), the factory gage usually cycles around 200* and both engines have provided a lot of trouble -free miles. Hope this helps.

    since my new thermostat, mine runs at 200* and no matter how hard i romp on it, never hotter. i like it running as hot as is safe for my fuel economy. :)

    A sender for the idiot light, I suspect.

    Sounds like a pipe plug ... like somebody blocked the sender off. :doah:

    But cool, as it were, sounds like the old girl is doing okay so far. Thanks all!

    Depends on what tempeture thermostat you have. Mine came stock with I believe a 195 one, and it's always stayed right around 195-200. I tried an 180 last summer and it always stayed around 175-185. This was all with a newer radiator, clutch fan, and water pump.
