Coolant Leaking Out!

[ga81peach19]

I have a question..I have a 91' Chevy Cavalier that I just purchased not to long ago and I am already having problems:

Main Problem:

Everytime I start the car it starts jerking, unless it is driven for a certain amount of time, then the radio and winshield wipers wont work until the car heats up (I guess) then I can turn the car off and restart it and they will work. But my main problem is everytime I drive antifreeze leaks out of my car and causes the temperature gauge to go all the way over. I got a hose (dont know which one) changed and it still leaked. I got some radiator stuff to try and plug it if there was a hole inside and it worked for a few days then i was driving and the temp went up and the hood started smoking. Someone looked at it and sd it wasnt leaking from the radiator hose (or whatever) ..but it is a hole somewhere under the hood and it leaks after being driven.

Question:

Could anyone suggest what I should do or might know where the leak is coming from? Is this a water pump or thermostat problem?

You will need to have the system pressure tested to find the source of the leak

sounds like a waterpump to me.

I found out my mats are getting soaked on the passenger side...I think the water or coolant (whatever) is leaking to the inside. What does that sound like?

That would be from the Heater Core. The little plastic tubes on them crack.

Under the dash. Center of the car.
