Asked by Aug 17, 2014 at 02:38 PM about the 2004 Pontiac Grand Prix GTP

Question type: Maintenance & Repair

I have a 2004 Pontiac grand prix that over
heated and was leaking antifreeze. There
was a hole in the lower heating hose (the
little elbow fitting under the alternator). So I
changed both of the fittngs put everything
back together and drove it about 3 miles
and started over heating again. Help! There
doesn't seem to be antifreeze in the oil, but
there may be some oil in my antifreeze
overflow tank. Could I have blown a head
gasket when it over heated, or could it be
something else? Help, I haven't been
working on cars long, so I'm kind of a
novice, so please keep the responses as
simple or as detailed as possible!! I
appreciate any feedback!!

Did you bleed the cooling system? Air gets trapped in the cooling system when it's drained which causes overheating. If it's like my '00 with the 3.8 V6 there's a bleeder screw on top of the thermostat housing (where the top radiator hose connects to the engine). With the engine cold, remove the radiator cap and fill the radiator with coolant, to the top. Now open the bleeder valve. After the coolant starts flowing smoothly count to 10 and close the valve. Top off the radiator one last time and you'll be all set. HTH. -Jim
