Had radiator, thermostat and heater core replaced on 2000 Blazer within the last 3 months. Since replacement, after warming up, the temperature gauge is always just below the 12'oclock position indicating 210 degrees. If idling, it moves to 210 exactly and stays there until I start moving again and then goes back to just a little under 210. Is this normal? I'm not towing or carrying heavy loads or running in 4 wheel drive. What is the correct operating/coolant temperature for my Blazer?
