Honda 1995 Civic DX loss of water.
Hello.
I have taken my car into the shop numerous times. They have replaced the water pump and the hose to the radiator/engine. They have pressure tested the whole coolant system and cannot find any leaks.
However, every time I open my radiator cap, it need lots of water. If I drive for long distances or go a week without putting water in, it usually overheats.
I, and the mechanic, are stumped. There also appears to be no apparent loss from leaking on the ground. In January of 2004 I had the head gasket replaced as well. The secondary symptom I have noticed is a decrease in fuel efficiency. I have no idea if the two are related. The car has had all regular maintenance and only has 104,000 miles.
Does anyone have any ideas of where to look? It appears that some people have had similar problems, but not as persistent as mine. Any advice is appreciated.
Thanks!
