Default radiator issue fixed car knocking and dies now - added video

I changed the radiator and fan assembly and after burping making sure hoses were clear it worked fine. But yesterday i was driving down the interstate and the car started to lose power. It started to make a knocking noise and when i tried the gas pedal the knocking got worse and wouldn't power the car. I got off the exit that was luckily right there where i was and stopped at a stoplight only to have the car die and cut off. I tried restarting, but it went er and didn't. I let off the brake and rolled down to an ihop and parked. It will start, but it makes the noise and i dont want to break it anymore than it is. Did it jump time or something? Should i take it to the Chrysler dealership and pay them the 90 bucks to check it?

This is what happens when you start it.
No overheating. Will die if you cut on AC. Transmission fluid fine. Oil is fine.

Did the PT overheat bad before you changed the fan and radiator?

It actually didnt overheat at all. But the shop told us it had a leak in the radiator and since i was replacing the fan assembly we went ahead and replaced the radiator too.

Before it shut off it wasn't overheating either. The gauge showed it about 1/2 way between hot and cold. I could feel some serious heat coming off the engine though and something smelled like it was burning.

All the electrical stuff flashed on and off but the battery apparently has a dead cell so we are replacing that today. I made sure that the battery connections and the connection to the starter and the grounds were clean and so when they get back with a battery i'm gonna see what it sounds like.

Good luck bro, I know a weak battery can do some weird stuff.

It could be a belt other than the timing belt. Before I bought my PT, I had an Eclipse. That car, at one point, was 'burning' serpentine belts left and right. It smelled like burning rubber. I'd have electrical going to everything, starter would click, but the car wouldn't turn over. Just an idea. (I'm female, so if I don't make any sense, just ignore me. I'm used to it. LOL)

I would say you have a pinched wire or a bad electrical problem.
Check the wires for burn marks around the Alternator, battery or in the engine bay in general.

Ok so replaced the battery because of the dead cell and changed the cables going from grounds and starter to battery and it started up. It ran fine for like an hour, but now it's overheating. I can start the car and drive 500 feet then the needle shoots up past half and keeps going. I shut the car off and am looking for issues, but i dunno. I am going to crawl underneath and check the oil for fluid. I am also going to open the radiator draincock when it cools down to make sure fluid is going through.

The low speed is working, but I will test the high speed when it cools down. It just started storming so i can't do much but have it towed back home.
