I seriosuly need some help here. the car is a 1998 integra LS. The car has been overheating on and off for a while now. I top the coolant off once a week and it is always empty by about friday. I have replaced 2 thermostats nothing changed I have checked the oil and there is no water in there. Theres no leaks anywhere that i can see, ive checked when its cold, ive checked when its hot, AND i even yanked the hood off and drove around like that for a while to see if it happened while i was driving. NOTHING Where could this water be going? Acura has looked at it and said the car is fine. But its obviously not. any help would be a BIG HELP im so desperate at this point.
