My coolant keeps leaking out! Help!

What is your question?

Recently I noticed my car started smoking but the temperature gauge never moved. so i had a mechanic friend replace the water pump. We've resealed and retightened everything about 4 times now. Somehow all the coolant I put in yesterday is gone. Help me... I know nothing about cars. Also there's a burnt rubber smell once it starts smoking or steaming. Side note: my ac compresssor needs to be replaced as well but it's not my main concern at the moment. I'm kinda broke

What makes this problem better or worse?

It starts to steam/smoke when the car sits still running

How long has your 2000 Ford Focus had this problem?

Going on 2 freakin months
