After my car has been running for a while the fluid in my antifreeze overflow jug starts boiling.

Welcome,

It sounds like your thermostat may be stuck closed.

You will find it under the cap at the end of the upper radiator hose. Simply unbolt the cap, lift it up. Pull old thermostat and put the new one in and rebolt the cap.

Let me know if this helped.

I don't have an online manual that show the hose ,but if you open the hood and face the motor it will be a big black hose about 1.5" in diameter on the right that runs from the front of the car to the top of the motor.

Here is a guide on how to do it step by step:
