I have a 2002 silverado and i just replaced the thermostat in my truck but its still operating at 200 degrees. is this normal or should i look further into it? and if not what might be the problem?

That is normal, just because the thermostat is 195 that has nothing to do with it reaching a higher operating temperature. 195 is the minimum before the stat closes to heat the engine up.

Yes, try a 180 thermostat, with a 195 the fans will not turn on until about 210.

the engine is designed to operate at 210 to 220 degrees, so all is normal

250 TOO HOT FOR ENGINE AND TRANSMISSION. SOUND LIKE COOLING FAN CLUTCH BAD ITS FREEWHEELING NOT LOCKING UP TO DIRECT DRIVE TOO COOL ENGINE OFF BECAUSE THE FAN CLUTCH THERMOSTAT NOT WORKING THE HOT SILICONE OIL CAUSE IT TO EXPAND TO PUT RESISTANCE ON CLUTCH TO PUT DRAG ON FAN CLUTCH CAUSING IT TO LOCK IN GIVE IT DIRECT DRIVE.I WOULD STILL REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP IF TEMPERATURE STILL 250 DEGREES YOUR RADIATOR AND COOLANT SYSTEM NEED FLUSHING.

200 -210 (f) is normal operating temp...your thermostat does not even open till it reaches 195 degrees. With a good pressure cap and 50/50 antifreeze mix you are in no danger at all of an overheat at that temp.

The thermostat for that vehicle should be a 190 or 195 degree rating. If your temp is moving up and down by only 9 degrees then the thermostat is probably ok. You might check your coolant level and make sure that it is at the proper level and that all of the air has bled out of the system. Do this when the vehicle is cold and never open a coolant system on a vehicle when it is hot.

95 - 110 is perfectly normal.

190 deg - 215 deg.

195 degrees is the typical high end on the thermostat (when the thermostat opens), so the temp gauge should read a max of 195 degrees, give or take a few degrees. Some people replace their thermostat with a lower temp one, such as a 180 degree one. Then the gauge will read lower (approx 180 degree max). So the range is typically from cold at start to just under 200 degrees.

The normal operating temp is 192 degrees(t-stat opens)
