Question about 2006 Pontiac G6

Engine Seized up on a 2006 Pontiac G6

Twice I noticed our 2006 Pontiac G6 stutter while driving. 5 minutes later, the engine dies abruptly! I coasted into a parking lot and pulled into a stall and realized that even though the engine was dead, I still had power steering the entire time I was coasting. All gauges functioning, no trouble lights. Felt as though the engine seized up. Took the battery in and it was bad, BUT upon replacing, the engine will crank over one or two times and seize again. Starter is trying to turn over the engine but there is resistance. Help?

    Coolant level fine, new battery. can I pull the serpentine belt and try turning over without pulling the plugs?

    pulled the belt and all pulleys are free. alternator inc. tried turning over without serpentine belt on and still barely cranks over once and siezes??? help?

    If all the pulleys on the front of the engine seized all at one time, the engine would snap the serpentine belt and still run. Put a wrench on the front crank pulley bolt, and try to turn the engine by hand if it only goes a short distance before you can't turn it put your tools away and go have a's over.

    sounds like a spun bearing or broken rod. either way, it is DOA too expensive to repair vs replacement in any form.

Check the oil and coolant levels. if coolant is low pull the sparkplugs and try to turn the engine over if still not turning free remove the serpentine belt and try again, if it turns over ok check the pullyes on the front of the motor to see if they all turn free by hand. a serpentine belt can prevent an engine from turning over if a tensioner, idler, water pump, alternator, or power steering pump is siezed up or starting to seize. being your battery is bad I'm thinking probably the alternator is seized. hope this helps mike.

2008 Pontiac G6, stalls while driving. Engine light comes on. Takes 5-10 minutes to restart, after each restart it would just die after about 30 seconds. Never kept it running long enough to get home.

Load placed on the engine takes place when the Compressor clutch engages. It will not engage if the system charge is too low on freon. It needs to be checked with a gauge, I think that may be your problem.
