The coolant level is dropping on my Rav4. About 12-16oz per 500 miles. I don't see any external leaks, no smell of antifreeze when I turn on the heat, no white smoke out the tailpipe, no chocolate milkshake on the oil dipstick or under the oil cap. A friend mentioned the intake gasket but the intake manifold is plastic so I don't think it's part of the cooling system. Just put a new radiator cap on it but I don't think that was the problem. I hear the sound of water flowing for about a second or two after first starting the engine. No problems with overheating....yet.
Any ideas where to look or how to troubleshoot this?
