I HAVE A 1998 PONTIAC SUNFIRE. IT WOULDN'T HEAT UP SO I CHANGED THE THERMOSTAT. AND THEN IT WOULD HEAT UP WHEN IT WAS SITTING AS SOON AS I WOULD TAKE IT DOWN THE ROAD IT WOULD COOL DOWN AND BOWL COLD AIR. AND I PUT CARDBOARD IN FRONT OF THE RADIATOR AND MADE SURE THE FAN COULDN'T COME ON. BUT IT STILL DIDN'T HELP. SO I CHANGED THE THERMOSTAT AGAIN THEN IT STARTED TO OVERHEAT (AND YES I BLEED IT EVERY TIME I CHANGE IT) ANYWAY SO I CHANGED IT AGAIN AND NOW IT HEATS UP TO THE RIGHT SPOT WHEN IT IS SITTING AND WHEN I GO DOWN THE ROAD IT HEATS UP TO RIGHT AT THE OVER HEATING MARK.IF I DRIVE 45 MILES A HOUR OR LESS IT IS FINE BUT IF I GO 55 MILES OR OVER IT HEATS UP TO THE HOT MARK.AND I TOOK THE CARDBOARD OUT AND HOOKED THE FAN BACK UP . SO WHAT DO YOU THINK IT MIGHT BE..THANKS
SORRY THE HEAD WAS CHECKED AND GOOD.RADIATOR IS FINE
I FOR GOT TO TELL YOU BUT THE FAN WONT TURN OF EITHER UNLESS I PULL THE FUSE
