Hello, I have a 97 Sunfire GT and had the same problem. The cap on the overflow bottle is pressurized and mine lost it's pressure. Once I replaced that I didn't have the problem anymore. !
You could also have a hole or crack in the overflow container
On my 2002 Sunfire it's under the dash on the passenger side.
Under the car, in the rear.
2.2L OHV engine 10.3 quarts 2.3L and 2.4L OHC engines 10.7 quarts
Under the car by the fuel tank
Try under the oil cap, oddly enough.
It is on the right side, under the dash, behind the glove box
first i would try the oil pan
its a sunfire and automatic you don't
Yes, but take caution.
What type of antifreeze do I use for a 2000 bonneville
where is the location posslook sensor three wires , 2000 pontiac sunfire
all the tire sizes that will fit your sunfire without havig to make adjustments would be 14, 15 and 16.
