Re: Lost (?) radiator fluid
Another place to check is behind the water pump where the tube comes out. Look for white stains on the block trailing back and down off the water pum on the side of the block.
There is an "O" ring that seals the joint between the tube and the back of the pump. If it gets "crunchy", it'll leak all over the block instantly evaporating leaving on;y residue.
If this looks like the problem, it'll be a kind of difficult to fix (strip off all attached hoses, unbolt the tube, pull the tube out, replace the O-ring and re-install). But once fixed, no more leak!
