Question about 1998 Honda Civic
Look at the oil on the dipstick. If its milky you have a head gasket issue. Also if you can make it to a smog machine they can sniff the coolant fumes to see if gas is in the coolant. Head Gasket again. Any repair shop has a chemical that can test for gas in the coolant also.
The theory here is if your losing water and none is leaking on the ground its got to be going into the cylinder and getting pushed out the exhaust pipe.
Now if its just overheating you may have a stuck thermostat or clogged radiator or a coolang fan that dlesnt turn on when commanded by the computer.Also if its just overheating and the water lost is going on the ground somewhere then you may not have a head gasket issue.
I just did a head gasket on a Honda because as the engine was warming up the overfill bottle would fill up and overflow. The combustion pressure was leaking into the coolant and pushing the coolant out.

OhOh.. Do this. Fill your radiator and thake the overflow open end, the end in the bottle, and submerge it in a bottle of clean water. Then start your motor, radiator cap on, and watch the end of the hose in the bottle. If you see bubbles, especialy smoke filled bubbles, you have a combustion leak into your cooling system,which, is your cause of overheating and coolant loss. In short, you have a head gasket problem. Sorry.
