210 is norm for most chevys, witch is good in the winter, if you live in hot weather go ahead and install the 180 degree thermostat
any vehicle with a 195 degree thermostat should run at 195 degrees. Assuming all components are working properly, there is sufficient coolant capacity, and the vehicle is not being used outside of it's design parameters.
195 may be the thermostat temperature, but in the case of my Z28 Camaro, the cooling fans are set to come on at a higher temp 230 (probably for sake of emissions), and then settle down to 210. In this respect, the fan sensors dictates your operating temp.
I would suggest you contact a GM Dealer about this. Almost all Chevy engines use a 180 degree or a 160-165 degree thermostat. I`m not going to say this is concrete but
I do not suggest getting the engine over 200 degrees. About all this new stuff has aluminum heads and heat is an enemy to them. Call the dealer !!!!!! GOOD LUCK
should be 180 degree thermostat.
That all depends on the thermostat that is installed. From the factory it came with a 195 degree thermostat. However there are 180 and 160 degree ones available. Under normal conditions the operating temp should stay around the temp of the thermostat installed. Some fluctuation is normal, especially in stop an go traffic when there is no air flowing through the radiator.
Most all vehicles these days use a 195 degree thermostat.
It depends on what temp. thermostat is in it.
Try changing the thermostat.
should be 195 to 210 normal operating temp
To control the flow of coolant in the engine, so the temp will reach normal operating range
the engine will take longer to get to normal operating temp. and the water temp could fluctuate while driving
The normal operating temperature is always dependent on the thermostat in other words a 195 degree thermostat will give you near 195 degrees temperature anything different will be a problem with either the cooling system or the temperature gauge
I assume where it has a 195 degree thermostat that operating temp should be in that range 190-220
temp should be 190 for a 4.0 ....AlsoIt depends on the thermostat that you have installed. If it's a 180 degree thermostat, the engine should run at right around 180 degrees. Recognize that stock engine temp gauges are notoriously inaccurate so don't blame the thermostat if everything else seems ok but the gauge says the temp is off.
