Hello guys I have a problem with the cooling system on my 2000 v6 well I changed the thermostat because I had a puddle of coolant sitting top of my transmission well apparently this fix the leak but so far I have put aabout 3 gallons of water in to the system and the water disappear and I dont see any leaks or drip at the engine compartment and the oil looks fine what can this be.

Thanks
