It goes through water and coolant way too fast, and Ive recently added water the past couple of days. It pushes water out of the overflow hose and I have to keep refilling it every couple of days. And when I drive the engine temp sometimes goes to the red then goes back to normal. Any ideas?
 
perhaps air in the cooling system might need bled out for the thermostat to work correctly. or thermostat is bad .
 
Did you pressure test the system to find the leak?
