2006 Chevrolet HHR Q&A
2006 Chevrolet HHR Question: what is the normal operating temperature?
The 180 degree thermostat dosn't open untill 180 or so, probably was just very hot outside so your vehicle was running hotter than normal. - hemicuda
While the thermostat may open at 180, the cooling fan does not come on until about 220, so if there is not enough air flow thru the radiator, the temp can rise - I have seen this while sitting in a traffic jam - as soon as you start moving again temp will go right back to normal 185 - dealer says is normal - lwrightcpa
What is the normal running temperature for this engine?
