The temperature gage in a 2000 Chevrolet 1 ton with a 454 should stay about in the middle of the temperature variation. It will probably run slightly hotter when towing.
190-200 is best temp any motor well run it, best performance's and life spanned
195 to 197
All depends on the horsepower and the traction you get, should run in the 13's.
Should be about 50% of your temp scale on the dash. As per manual. Info courtesy of www.Dranoweb.com
198 degrees min running temp. 210 max running temp. The hotter the temp the more fuel economy.
if you have a differential temp gauge installed the temp will run a little lower than engine temp it is close in range, but generally a little lower
Around 190-210
If you are asking about the water temp, older ones were usually 180, newer ones were 195. If you are asking about the exhaust gas temp, 1350 is safe.
Most engines run in the 195-220 deg F area.
185-220 deg F
YES- 104 is a very high temp...especially if he's had it for several days...he should see a doctor.
