Please help

Hello everyone, first of all happy to finally become part of the community. I own a 2007 chevy cobalt LT with 111789 miles on it.

So my problem, my radiator started leaning fluid when i was aproximately 3 miles from my house. When i was a mile away my car was dinging about it over heating. I then pulled over, let it cool down and drove it the one mile to my house. I relaced the radiator and everything as well as spark plugs since i just rolled over 111k. I drove it around 60 miles and ran the engine block test on it (from oreillys where you use the blue fluid and vaccuum like tube to test for gases in the system) 5 times. Each time the fluid never once turned color. Then i drove about 4 hours and now have about 400 miles on the vehicle since the incident. And it wont start. It trues to crank but wont fire. I went under the hood to check fuses and notice my radiator resivoir was lower than before. I then checked my oil and it seemed to be unchange from when i got my oil changed a week prior. Idk what is going on.

Any ideas?
Also, if i have a blown headgasket. Do i do thenreplacement or swap an engine?

Hey! Welcome to the forum. Have you checked for the radiator any leaks? Check upper and lower radiator hoses, especially upper leading towards the backside of the block driver side (thermostat location). You can also have a pressure test performed where they test for proper pressure in the system to determine if a leak is present.
If you were to have headgasket issues, look at your color of your coolant reservoir fluid. If it looks like chocolate milk then oil is present. Another telltale sign is to look at your oil cap and inspect the underside of it..if it looks like coolant, then that's a pre sign.
