Good morning Myla. Nice to see you today! I'm sorry to hear you are having this problem. I know this can be frustrating. Please give me one moment to type out some information for you. Sit tight one minute. I'll be right back!
Thank you for holding Myla,
The problem you are describing sounds like you either have trapped air in the cooling system or you have a failing engine thermostat. I would start here with having a cooling system pressure test performed to me sure the cooling system is able to hold pressure as needed and if that checks okay then the next step would be to replace the thermostat and rebleed the cooling system to remove any trapped air.

Okay, that does not necessarily mean it has not failed again, the fact that the temp comes up and drops along with the heater going from cold to hot does indicate there is a coolant flow issue so the pressure test needs to be done which will also verify if the cooling system is completely full with no trapped air.

The cracking noise does in fact indicate the cooling system is low on coolant and you have trapped air in the system.

okay can i just add coolant to it? OR do i have to flush the whole system and read coolant and will that help the heat not working?

You can try adding coolant but if you have trapped air it will need to be bled or you will not be able to get the trapped air out.

The best way to bleed the system is with a vacuum bleeder and unfortunately, if you do not have this tool and or the Air to run it then you are best served here to take it in to the shop.

No, it does not sound like the radiator, it sounds like you either low on coolant with trapped air or the thermostat is failing.
