low coolant but no leak
My coolant is going somewhere but I see no leaks.
I don't know what it is. I've changed the reservoir,
the o rings I flushed out all the hoses. Any answers
Possibly a head gasket, have a block check test performed that will confirm or deny a blown head gasket.
Had same problem with a 2001 Mercury Sable the way I stopped the leak is removed top hose going to radiator and poured some Aluma Seal Stop Leak into hose then reconnected hose and that took care of the could not found anti freeze leak.
Don't put anything in the cooling system especially that car, there are way too many small cooling ports in the engine as well as the radiator and heater core, small enough that that stuff will block them.
Only will clog if you use more then what is recommended if does not stop leak the first time do not continue to add more hoping it will work that is when you can clog up the cooling system.
