We replaced the temperature gauge in my 1991 Chevy blazer what is the normal operating temp?
The normal operating temperature for a 350 crate motor in a 1972 Chevy Blazer is averaged at a temperature of around 180 degrees and 190 degrees, apparently depending on the kind of thermostat one uses.
It should have a 195 degree thermostat.
Factory said to use a 195 degree thermostat
what should my dash gauge read for normal opp temp on my 97 Chevy 5.7 liter vortec
It's lean.
The temp blend door actuator is probably at fault.
I have a 99 2500 454 the temp runs at 210
Yes it sure can.
A bad engine temp sensor can do that.
Neither, I believe it's electric.
temp sensor - sends signals to the computer for driveability temp sender - measures temp and sends to gauge in dash
