1997 Toyota corolla slowly loosing coolant but i see no leaks?
I haven't added coolant yet but it is pretty close to the low line. But i see no leaks. What could be causing this?

Coolant doesn't just evaporate or disappear, it has to go somewhere.
If it is not leaking externally, it's leaking internally. Look at the engine oil and under the oil filler cap to see if the oil looks a little milky. It could also be leaking into one or more of the cylinders and being burned up by the combustion process.

Check the water pump shaft seal weephole. It only leaks under pressure and coolant dries quickly when the engine is hot.

Get the cooling system pressure tested. If no leaks show up the head gasket may be going bad and you're burning antifreeze slowly.

Probably a leaking head gasket. But look closely for crystalline deposits which antifreeze leaves behind.

It could be leaking into the combustion chambers, then coming out the tail pipe as white smoke.

it either has a leak or it has a blown head gasket and coolant is getting into the cylinders and burning.
