"Normal" temperature is based on the thermostat, as least once the engine is warmed up. If the thermostat is working properly, the coolant temperature should stay around 195 degrees (F), but will vary by a few degrees, up or down.
Also, if there is no air flowing through the radiator, as happens when you are stuck in traffic or stopped for a long period with the engine running, then you may see the temperature rise on the gauge, until the cooling fans turn on.
I have provided a link that will give more details about how the cooling system works.
Good Luck, Greg
The 2000 Chevy Corvette normal operating coolant temperature is 195 degrees. You can install thermostats that will allow the coolant temperature to only run at 180 degrees.
195 to 210 degrees is normal.
The 2003 Chevrolet Venture coolant capacity is four gallons. The coolant can be mixed 50 percent anti-freeze and 50 percent water.

Blown head gasket.
for my 2000 Chevy Venture I use DexCool. It is the ONLY one recommended by GM.
The factory thermostat, made by Stant, is 195 degrees Fahrenheit.
They are not designed to work at normal operating temperature They are designed to work when A/C or defroster is on and/or engine coolant temperature exceeds 235 degrees
The computer on the 1997 Chevy Venture is located inside the engine air filter. The computer is surrounded by a semi-clear white plastic coolant reservoir.
It would have a 195 degree thermostat so it would be in that range.
The radiator drain plug on a 2004 Chevy Venture is located at the bottom, left side of the radiator. It allows for the coolant to be quickly drained during maintenance.
because your coolant level is too low. put some antifreeze in it......
