Check the obvious and easy stuff first i.e. leakages from the expansion tank, radiator, hoses. If that fails to reveal the problem, then get your mech to do the radiator compression test but make sure the engine is cold. From past experiences, when the engine is hot, we have almost always fail to detect the leaks.In my case, I was loosing 1/2 liter a week. There was a crack on the lower part of the expansion tank. Changed the radiator. Did not leak as much, about 50cc a week but I was still not satisfied. Turned out that the radiator cap was allowing some water evaporation/leakage. Now I hardly have to top up. Peace of mind. :yahoo:</blockquote>
