It has to be going somewhere. Have you ever noticed white smoke from the exhaust? Is there anything in the oil (not just the cap)?

There has to be a leak then. What I suggest is to get a cooling system pressure tester from a parts store. Most will lend them and pressurize the system and check for leaks. DO THIS WITH THE ENGINE COLD. Remove the rad cap and install the hand held pressure pump and take the system to the max pressure listed on the radiator cap. Check all hoses, check around the head, check freeze plugs.

PS: Sorry it took long to get back to you. For some reason the notification on my email took it to spam.

That would be fine. However, I recommend you keep a close eye on the coolant level. Make sure it is always full; otherwise, you will end up with new problems.
