It overheated the other day....took it to the shop and they said it was 1.5 gallons low on antifreeze...they pressurized it after refilling it and ran multiple tests and couldn't find any leaks or anything.....A week later I checked it and had to add a whole other gallon in...no leaks or anything tho that I can see..also the coolant reservoir is always empty but there aren't any leaks in that either I checked it. ......where else could the antifreeze be going???...any suggestions as to what I could try or what it might be.

Option 1 - Auto Zone or automotive parts store has a solution that you pour in the radiator, run the engine and stop it. Then you put on the glasses and use the IR light supplied to spot the leak. These is used in oil also to spot where the oil leaks are coming from
Option 2 - Check out your water pump. Check the little weep hole that is on top and see if you spot any water marks on it. I had the problem on my Ford Explorer and had the hell of time finding the leak. But when all else failed I replaced the water pump. Lo and behold, I guess the water maybe had to get really hot, but on the weep hole you could see water marks on it. But that was good, cuz most of the times water pumps go out when you least expect it.
Option 3 - Going for the weird now. Check the pressure in each spark plug hole. IF you blew a gasket, it is "possible" to leak water out. Is there any water coming out of muffler. Has the engine been running a little rough lately. Go to the car wash and wash the engine good. Reason is if you put the ultraviolet solution in, you may spot it coming from the sides of the heads or head of the engine.
Option 4 - Check the oil when the engine is cold. If you see ANY condensation on the dipstick or ANY "White oil" substance at the tip of the oil dip stick, then you got a big problem. Possible blown head gasket or worse.
Option 5 - On the passenger side, is there any wet spots in side. Is the carpet wet as this is indicative of a leaky heater core. Also check the heater core hoses going into the car, from underneath the hood for any possible small leaks. The ends may get hard and crack, leaking water AWAY from the obvious places like the radiator, water pump, and radiator hoses.
But do the ultraviolet solution test, after you have physically and visually checked the heater core, hoses, and the muffler tail pipe for excessive water. I presume that you have taken out your reservoir bottle and check it for leaks. But if you do the solution bit and run your engine then don't forget to take out the reservoir bottle to check it with the light underneath and on the sides of the bottle for possible leaks.

If the overflow reservoir is always dry, I'd check it again for leaks. When the coolant gets hot it expands and the only place for it to go is this reservoir. If it's dry, either the cap is not allowing the coolant to flow to the reservoir or the reservoir is cracked.
Otherwise, check the floor of the garage for evidence of leaks and look directly above and near the spot. It could also be a freeze plug in the engine block.
My bet is on the reservoir. It's worth one more check!
Good luck

well if it overheated into the red zone it may be internal problem that was not detected at the time of service no test is 100% and also if your burning a gallon of antifreeze a week that's just the beginning of a major problem next you will be burning the whole coolant system in 5 minutes so best advice get a second option from another repair shop look in your yellow pages

Blown head gasket would leak the antifreeze into the cylinders and start burning it. Does your jeep lack power, exhaust smell sweet, or anything like that? Did they do a compression check? Thats about the only other place for the antifreeze to go besides a leaking heater core inside the vehicle.

it might desire to be leaking interior the heater center. whilst a heater center is going out, the anti freeze leaks. each at times outdoors the motor vehicle, or each at times interior the passenger floorboard, or interior the heater center itself. which if so you will desire to locate out quickly earlier it starts off overflowing interior the truck. whether it is no longer the heater center the only different element i'm able to think of of appropriate now could be a crack interior the motor, and that i individually desire on your sake that, that's no longer it. optimistically i became a minimum of a few help to ytou. good luck
