My wifes car overheats sporatically. We have replaced the thermostat 2 times. The water pump has been visually checked for signs of malfunction to include the tell tale bubble and pulley. We have taken it to the toyota dealer in anchorage, ak. They say they can not pull a code or find a problem. But, the car still uses about a gallon a week of antifreeze, and will overheat. Any ideas?
