Overheating, codes P0014 and P0024

Hi, so my car has started overheating a lot lately and we took out the thermostat and replaced a busted tube but it's still leaking in the front center. When we squeeze the hose it doesn't feel as if any coolant is moving through. I drove it yesterday but it made it a mile and all the water/coolant had leaked out causing me to barely get it back home. It's sitting out in my driveway right now. We hooked it up to a code reader and it didn't throw any codes for a water pump but however threw out p0014 and p0024. I don't think those have anything to do with my car overheating though but I know they are very important to get fixed just not sure how to fix it. I can't afford a mechanic as I'm a single mom barely making it already but I've heard it's very hard to change a water pump on my car due to the timing chain. Could it possibly be something else besides a water pump causing the leaking and overheating? I know since the hoses feel like nothing is flowing through them that it's more than likely the water pump but if so, is there anything else I can do (a possible solution I can pour into the car to help it) or anything that would help make it run just a little while longer until I can get the money up for a mechanic? Thanks!
