pontiac overheated now wont start

Asked by NicknBritt Jul 19, 2016 at 06:53 AM about the 2004 Pontiac Grand Prix GT1

Question type: Maintenance & Repair

I have a 2004 grand prix.

I was driving my car and noticed my engine temp
was running hot car read shutting down ac to
protect engine and it started smoking.  my friend
went to get my car drove it home to his house
about 6 miles he said it did fine
next day he tried to bring it to my house which is
about 10 miles and 90% of the way here it died. I
had the tow truck pick it up and bring it home. we
replaced the waterpump, filled it back with
antifreeze and car still continued to overheat so we
replaced the thermostat. sounded like there was
air in the cooling system and antifreeze was
bubbling and shooting out the overflow so we tried
to bleed out the air using bleeder screw.. car coled
down a little tiny bit then got hot again so shut off
car. once cooled we put water through the radiator
and restarted the car letting it run trying to filter it
through hoping to get out the air bubbles. it again
cooled down bit then got hot again car was
chugging at idle we drove it one block and back
parked could hear noise by tail pipes like they were
shaking and sputtering sounded loud. frustrated
we turned off the car and called it a day.. next day
went out and tried to start the car and it wont turn
over. lights come on, makes a slight noise when
attempt to not a clicking noise or a chugging noise
like it's attempting to turn over.

it's in the shop and they can't find anything wrong.
if this helps my abs light has been on for awhile.

Your mechanic should be able to figure this one out. If it won't start, there's something wrong, and their job is to figure it out. What trouble codes is it showing? Could be a number of things. Unfortunately repeatedly overheating your engine may possibly have ruined it. If so, its time for a different car. Do not spend vast sums of money on a 12 year old GP/ However it may be repairable without spending a fortune, so follow you're mechanic's advice, within reason.

Sounds like 2 separate problems. Is there air trapped in the cooling system? Is there an internal leak causing you to loose coolant? Have the battery load tested. It may be worn out. Make sure all electrical connections, including grounds are clean and tight.
