Losing Coolant - 9/14/2004 1:00:23 PM

Can anyone help me? I have been losing coolant in my radiator for about 2 months now. I have to refill it every 2 or 3 weeks, but I can't find a leak anywhere, and the oil seems to be free of water or coolant. Any ideas. I am scheduled to take it in on Friday, but I would like to know what I am looking at before I get in there.

You haven't found any visable external leaks, and there is no evidence of coolant finding it's way into the oil. Ok, apparently you have a steam engine now. What might be the problem is a head gasket, head, or intake manifold might be slightly cracked or eroded next to a place where the coolant can find it's way directly into a cylinder. If it's a minor enough leak, which your's sounds like it is, the engine will burn the coolant right along with the air/fuel mixture and not cause any runability problems, for example: white steam in exhaust, overheating, engine misfire. Check for bad head gasket, cracked/warped head, cracked/warped intake manifold, or God forbid, cracked engine block. Most likely, in my opinion, minutely cracked head gasket next to cylinder is the problem.
