My 2005 300c Hemi knocking and won’t start


#1

My car started overheating yesterday so I checked it and filled it up with antifreeze but the it started smoking again and then shut off. The only way I can get it to start is if I pump the gas pedal the whole time but it gives off a really hard knocking sound like there is rocks bouncing around in the engine

your motor is fuel injected. you do not need to pump the gas pedal
if you want, hold it down 1/2 way as you crank. that will richen the fuel mixture
it does not sound good though from your description.
tow to a mechanic to have him give you the news?

You overheated the engine and destroyed it. Get ready for a very large repair bill, or get ready to scrap it. Sorry.
