coolant disappearing from fill tank

no visible leaks, no overheating, no antifreeze in the oil, new waterpump... recently drained and refilled the radiator to remove the air... if it's a leak it's a small one... could it be so small that it burns off/ evaporates before hitting the ground?

You could try getting a pressure test?

check rubber hose that goes into oil cooler, sometimes its broken and it slowly leaks out most of the coolant

or one of your coolant caps is bad and it's evaporating - and that's a cheap easy fix

also check over flow hose going into reservoir, it may not be attached!

it also can fluctuate if the car is hot or cold (expansion and contraction due to heat and pressure), but i'm sure you know that...

it fooled me once tho...

lol... i wish all my questions in life got this much feedback. here's an update though: i was actually parked on a hill and observed a small leak... i went back to my garage and sure enough one of my hoses was wet along the back. i examined it, no cracks, but the hose clamp did seem loose, and the hose itself was sitting low on the connection. i took it apart and put it together with everything tight. this would explain why i wasnt seeing a leak: it only presented itself in certain situations i.e. parked on hills. so i'm keeping my fingers crossed. update in a week. thanks for all of your help so far though
