Unlikely the engine has seized but all this wrench talk keeps the curious entertained.
Overheating the engine will result in warped cylinder heads and no compression. The engine will crank with no resistance, the cranking will sound abnormal.
Most major engine repairs are beyond the average person’s ability, but this should not mean we should give up with diagnostic advice unless you are someone who does not replace damaged engines.
With new and used car prices as high as they are right now, I would normally say something like this is worth fixing. The Chrysler 2.7 is another story. I knew several people with them and they all experienced major engine problems. One guy made it to 150K and the tow truck driver that came and got him when it let go said he sees these all the time but he did much better than most with that many miles before it blew up.
This is a badly designed engine which is too bad because it actually performs and runs nicely before it goes to crap. One of my buddies looked into replacing the engine. Everyone told him to retrofit it with some other Chrysler engine like a 3.2 or 3.3 (I forget). You needed a donor parts car as I remember to make this economical as several things need to be changed. I remember him finding a guide online that told exactly how to do this swap and end the misery of the 2.7. He ended up doing the math and it wasn’t economical so he got something else.
If home was any more than 3 miles away it probably over heated badly. If home was more than 8 miles away the engine is probably seized and ruined.
No one I’ve talked to can figure this out seems kind of silly. Nobody knows what happens when you keep driving with an overheated engine?
Maybe the people he has to talk to don’t know anything about engines…
