I need help with a 2000 Honda Civic 1.6L SOHC. When I drive the car, I lose heat (inside blows cold air) and the heater gauge climbs (red line). After a few moments, I get the heat inside the car back and the temp gauge goes back to normal. When I check the radiator, the coolant level is down, but the overflow is full. I can pour the excess from the overflow to fill the raditor. Sitting (in driveway throttle in various modes) I can't get it to overheat and seems to run normal. Only can get to overheat when the car is moving. I have replaced thermostat (twice in a month), pump, raditor & cap. Purged the cooling system of air and still get the same result.? To me seems like a thermostat problem, but have put new ones in with same results. Head gasket or something simple? I can only drive for a very short distance before it does this. Thanks for any help.
have the same problem?
