Why is my Chevy Cobalt overheating?
While there are a variety of reasons your Chevrolet Cobalt is overheating, the most common 3 are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
What should the coolant temp be on a Chevy Cobalt?
I asked an “online GM mechanic and this is the response I got “Hello, and welcome. the normal operating of the engine should be between about 185 to 220. the cooling fan wont kick on until,223 degrees for low speed fan operation. your temp reading that you are getting is well within its operating range.
What should the temp of the coolant be?
The thermostat OPENS at 195F degrees; but, the temperature continues to rise to the normal operating temperature. The temperature of the coolant can rise above 212F degrees because coolant is pressurized (NOT because the water is mixed with antifreeze). Boil-over won’t occur until about 265F degrees, because of the pressurization (15 or 16 psi).
What is the normal coolant temperature of a 2009 Chevy HHR?
That being said, most average temps would be near 185/200 F The HHR is a GM vehicle where the cooling fans come on at 228 degrees F and shut off at 208 F. This is while sitting still as running down the road the fans are usually not needed at all. I’ve never tried SiriusXM – what makes it so good? See for yourself.
Why is the thermostat on my Chevy Cobalt not working?
Cobalt Thermostat Wiring – If the thermostat itself isn’t the problem, it’ll be the wiring/sensor associated with engine water temp detection, or the coolant temperature sensor itself.

What should the coolant temp be in a Chevy Cobalt?
Here are the specifications. • Engine coolant temperature (ECT) exceeds approximately 106°C (223°F). • A/C refrigerant pressure exceeds 1 310 kPa (190 psi). • After the vehicle is shut off, the ECT at key-off is greater than 140°C (284°F) and system voltage is more than 12 volts. The fans will stay on for approximately 3 minutes.
