    hi guys. today i took the car to do some stings and i got back to the parking lot and car was kinda shaking.

    i turned it off and back on. and still shaking.

    i parked it i looked under the hood and the radiator hose was FLAT . like sucked in . no air.

    i opened the radiator cap and allowed air in and it went back to normal. i notices that coolant is almost gone and before that it was full all the way.
    i added some water and tried to turn on the car and it didn't turn on.

    making some loud noises.

    its not battery. i think i even saw a service engine for a second.

    please help im stuck in a different state.

    car details on signature.

    Does it even try to fire?

    Or does the starter just crank and crank.

    Was it making a knocking noise before it died?
    Did you notice a wet trail behind you?

    Sounds like the starter is grinding on the flex plate or inside itself.

    The engine doesn't sound like it's turning over, like the post above, it sounds like it's grinding. It's most likely the starter that's at fault. As with the radiator hose being sucked in, I have seen this before. It was when somebody mixed dex cool and regular green coolant. I flushed the system and replaced the radiator cap and thermostat and that solved the problem. I believe it was the radiator cap that was letting too much pressure out. Then when it cooled back down, the system would go into negative pressure. The tube from the radiator cap to the overflow tank was plugged as well.

    it was sucked when i was still driving. a scond before i parked i felt it shaking. and i got it into the parking lot. do you think theres hope for the engine?
    the car has 216k on it but it was running smooth like a new car. no noise or anything.

    i must say i saw some white smoke coming out of the exhaust but maybe maybe its cz its cold. or maybe gasket going bad.

    Sounds like a dead stop on the flywheel to me. Get it turned off that spot and it should at least turn over.

    Does the oil look like it should or is coolant in it? That's usally what causes white smoke.

    My guess is that there's coolant in it, which killed your rod bearings. In that case you would need a complete overhaul or new engine.

    Best case scenario, you could replace the head gaskets, but my guess is that chance has come and gone.

    Oil color was normal. No oil mix with coolant.

    Your started is either broken or binding up.

    Or the motor is locked up. Try and turn the motor over by hand, maybe even pull a few spark plugs to make sure its not hydrolocked.

    Is it possible that the engine died? Is this how dead engine looks like?

    Dead engines look like good engines unless you throw a chunk of rod through the block...

    Pull the starter and try to spin the motor by hand. Take the starter to advance or wherever and have it tested. Change the oil and check for metal flake. If all that checks out, do a compression test.
