    Hey All,

    On the way home from work today I noticed the Temp guage
    go to 200 and then dropped back to 175ish. Rig is quite
    new "to me" and seems to be running hot. In the 190ish
    range most of the time. Is this above normal?

    Truck has an oil cooler in addition to a tow package
    from the factory. Other info needed?

    Rem, sound pretty much normal for that year Blazer, if you notice it hanging around 210 alot swap out the thermostat, and have the raditor cored anf flushed

    My 87 does the same thing. When I tap on the gauge face, the needle drops back down to 180-190. I feel the factory gauges are cr@p, so I'm installing Autometers at some point.

    thats more than ok. the hottor you run the more efficient you run to a point. plus the factory gagues arent that accurate. try placing an accurate thermometer in the radiator inlet and establish the basline that your gague is off

    200-210 degrees is pretty normal for later model fuel injected engines, though I would recommend replacing the thermostat as it sounds as it might be sticking a little.
