Loosing coolant, every couple of days have to add coolant to reservoir, not hot. on 1994 Saturn SW2

Not overheating and no visible signs of leaks

Asked by for the 1994 Saturn SW2
are you blowing white exhaust if so you have a major problem because its in the combustion chamber or an intake manifold gasket. your oil will show signs of it
No exhaust is clear.
then check your oil. possible intake manifold leak
No water in the oil either.
this is what I was affraid of sounds like you may have a cracked cylinder wall or cracked water jacket in the head
