I have a 95 honda accord, what's wrong with it is that everytime I added coolant water...a week or two later, the water keep running low?...any thoughts?

 

You've got a leak somewhere, either externally (hose, radiator, heater, etc) or internaly (head gasket). Is it running hot? Are you adding to the overflow tank or directly to the radiator? If you let it go long enough, will the level in the radiator conintue to drop or does it only empty the overflow tank? Any evidence of water in the oil (it would look brown and foamy)?

 

Externally, there are no coolant water that would be visibly coming out the radiator. Internally, I'm not sure but I was told that when you pour coolant water into the radiator,if there are bubble or foam coming out the radiator cap top, means that your head gasket is bad. And that seems like not the problem either. As for water going inside the engine, NO, that's not the case either. Another question that I wanted ask is that if this continue..what's the worst can happen? Any other thoughts...

 

happens in my car too.
after like 3-4 weeks the extra resevoir tank will be empty
