2000 Chrysler 300M

Asked by May 03, 2017 at 03:59 AM about the 2000 Chrysler 300M

Question type: Maintenance & Repair

I have a 2000 Chrysler 300M  and it started
over heating out of nowhere. We got a new
radiator cap and it seems like since we put
the new cap on we can't keep water in it.
The guage will go up to the half mark and
when I turn on the heater it stays steadily at
the halfway​ mark or just a little below. I
started it today and the engine light came
on and I put a little bit of water in it. Started
it up a couple hours later and it was making
a squealing noise and quit after and few
seconds and the engine light never went off
again. Could you please help me out with

Head gaskets are suspect, as far as the squeal, could be anything belt driven, alternator,water pump, even belt idlers. This defently needs a professionals attention.


Try purging the cooling system from air if you have not done so after refilling it. Here is a video on how to do that, https://www.youtube.com/watch?v=zUpXgAJ1gjU
