Recently, I replaced the radiator cap and refilled the coolant. After maybe a month and a half, the coolant level has gone from "full" to just a 1/4 inch above "add". I don't think there is a problem with the radiator cap. I also checked the oil level, and it has not changed and looks normal. I don't see any evidence of a coolant leak inside the engine. I also don't think there is any coolant dripping on the ground, but I will clean off the garage floor and place some cardboard down to be sure.
This might have started earlier this year after the water pump went out, causing the engine to possibly overheat multiple times with no change to the temp gauge (just some smoke and a flashing battery light). I'm still not sure if the engine truly overheated or if the smoke was just from coolant on the engine. I replaced the pump and had the coolant flushed and refilled. Everything then seemed fine. I can't say how the coolant level was acting before the water pump replacement because the Jeep was relatively new to me then.
What are some possible causes of this, and where should I look? Is it possible that the water pump ordeal caused damage that started this?
