My 2009 Challenger with the 3.5L overheated on me last night and now I have a horrible knock/tick.
I had noticed that it got hot a day before so I was watching the gauge like a hawk. Last night it was staying steady in the middle.
I was on the highway for about 2 minutes and noted the motor started to sound abnormal. I pulled over to the side of the road and found that the reservoir tank was bubbling over like mad. The gauge was still at half way so I suspect that there was an air pocket in the cooling system where the sensor was or the thermostat is stuck closed.
I did not suspect it to overheat on the highway since it was only 7 Celsius here plus with the highway speed air flow going through the rad.
The car is new to me so I have no history. It has 49 thousand miles on it.
I let it cool down and the oil still looks clean as does the coolant and they are not milky. I started the car again and it has a horrible tick/knock.
I have attempted to attach a video of the horrible sound.
My cousin was thinking the sound might due to the coolant channels being empty and possibly the knock sensors?????
I am planning on replacing the thermostat for sure. Just wondering if anyone thinks this is the issue or do I have bigger issues and I should start by removing the head, not the thermostat?
I am thinking that I have bigger issues and its time to start at the head.... Although I don't have much to loose with doing the thermostat and making sure the system is full off coolant again.
Mods so far.

Oh damn... well guess the warranty is outta play. You still may take it to the dealer and let them diagnose it, but not do any repairs...
I agree with Ghost.. if you threw a rod, or spun a bearing, that's gonna be expensive. I don't know with a spun bearing that you'd have the codes and low oil pressure. I also do not think replacing your thermostat is gonna fix the problem.
ooooooooh - got some bad news homey - if that knock is a rod - that engine is a boat anchor or an EXPENSIVE fix - sorry
That is not an exspensive as you would think. You can get a replacement for under $1K. 3.5l are readily available.
