My dash said check coolant level. I checked it and it was empty. I put antifreeze in it and drove a short distance and checked it and it was low again. I filled it again and parked it. Today it was empty again. It never overheated. I can see where it drips from onto a little shelf of metal like half way between the front of the engine and the back on the driver's side.

Hi,

Can you get a picture of where it is leaking? If you want to be sure to find the leak, you can pressure test the system which means you get a system pump and put about 15 PSI of pressure in the system then look for leaks. Doing it this way allows you do it with the engine cold because when it is hot, it makes it harder to look around and the coolant itself is hot.

Let me know if you can get a couple pictures of the area and we can go from there. If you can get one further away and then one close up that would be great so I can orient myself. Thanks
