top it off and see if it happens again... if its not below freezing outsied just put some water in it... tell me the outcome

correct me if im wrong, but headlift would cause a lot more than just overheating... i wouldnt diagnose it as headlift until everything else can be proven wrong...

Did you fill the system at the rad cap? When your car warms up, do you have heat?

i have the same problem and some people told me it was headlift and some said headgasket. i now know for a fact its my headgasket because we have an emissions tester in my auto class so i stuck the sniffer in my radiator, just after it filled the reservoir, and found about 85 hydro carbons. which means that under boost my bad headgasket/warped head pressurizes my coolant system and puts it in the coolant reservior.

I had a head lift too... But I checked all the basic things before.

and to be sure for a headlift, go to a radiator center and have the coolant tube test.

It's a tube they stick on the radiator cap hole... and they mesure the coolant pressure, also if micro bubbles show up (like soda, but smaller) you have the head leak!

So start with checking lines, rad and reservoirs for cracks. you may want to change your thermostat and thermoswitch (average $40 for both)
