Engine shut off while driving, will not turn over, battery light on and green liquid is leaking out

Hello, I have new spark plugs, wires and radiator installed before buying it. A few months ago I was having problems with my car overheating very bad. This was because I needed a new water pump and timing belt. I didn’t drive the car until I had the funds for the labor and parts. Weeks later I get someone to take me to an auto parts store to purchase antifreeze and the parts for the car. I start the car and the check engine light is no longer there and everything looks fine. I proceed to drive to the mechanic to try to get it there without the car overheating. As I’m going up a hill the car suddenly stops and the battery light and low oil light comes on and green liquid is leaking. The engine is also not turning over if I try to start the car it sounds like it’s trying to turn over but doesn’t. I never made it far enough to get near a mechanic and had no choice but to tow it back to my home which was closer. Not sure what else is wrong the car but I would like a second opinion as well before the mobile mechanic shows up.
