Chrysler 200 won't start

My radiator hose came off, purchased another and
car kept trying to run hot, maybe two week's after
while driving the car started to lose speed, run hot
and then it shut off. Had to have vehicle towed
home and since then the car will not start, all
light's, radio ETC comes on but car won't start. I
was told it was my timing belt/timing chain.
Anybody whom has or had this car had this issue
or something similar??
