Lost (?) radiator fluid

I first want to thank all of you for all the great info I have gotten from reading all the postings. Now, for my question...I have a stock 1.3 and have had to refill the overflow bottle alot (every few days, or so) lately. I can't find any leaks and she doesn't seem to smoke (steam). I had replaced the thermostat (when I rebuilt the motor). Has anyone had this problem and is there a fix?
Thanks in advance,

Check the Temp. regulator on the fire wall for the heater.
It's thin wall brass and they like to corrode from the inside and have tiny pinholes. Also you might want to check the small Choke heater hoses too. They like to leak with age. I just had one blow out on me one the 4th.

Hope this helps.

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!
