i had a coolant leak on my 2008 that i found was the lower intake manifold gasket. when it was apart i found that it hadn't been leaking long as there were no real witness marks from it. after replacing that the visible leak stopped, and my MPG went back up to normal. however, i still seem to be going through coolant. i only know this because after a week or two of driving i start hearing a rush of coolant into the heater core on a cold startup. i have replaced the radiator, due to an unfortunate drill bit incident, and that is when i noticed a leak was possible (not sure if i was hyper aware of the coolant system or if it is related). i have seen witness of a leak at the rad cap (and have a new one on order today) but it never seems to be wet when i check it. the temp is fine and i dont see anything around any of the hoses i removed from either job. also, the overflow is always full and i have never had to fill it the last 3 years i have owned the jeep. i am using the correct coolant but not sure what has been done before me. the water pump is also new. i am lost in the coolant system and am wondering if anyone could point me in a new direction.
thank you
