    If you have coolant in the intake DONT TRY TO START IT. the water (coolant) will not compress and might end up bending a rod or busting a piston. have you had any overheating issues prior to this? Might look at the head gaskets.

    Thanks,

    yeah take the plugs out and unplug the coil packs turn it over a couple of times and replace the plugs.

    See if that helps.

    Pull the plugs out, and put a 1/2" drive ratchet and socket on the harmonic balancer bolt and turn the engine over clockwise by hand. I don't remember the size of the bolt head off hand, but its pretty large, something like 18mm.

    If there is water in the cylinders, doing that will push it out and you'll know if it may have been hydrolocked.

    The man speaks the truth That way you are turning it over a 0 rpms (almost 0) so you risk less damage (unless your fucked already) If water comes out then you could be in deep shit or you may luck out........Only time/testing will tell

    Do as these guys said.

    And its a 24MM bolt. I only remember because the socket fell off 100 times last time I took mine off.

    Oh....one last thing now that I think of it....which is very important. If water does come out or you find another problem, CHANGE YOUR OIL ASAP! Disconnect the coils and pull the fuse on the fuel pump, crank your car over til you build oil pressure. That way, your car has pressure built up and is fully lubed at low RPM's. Reconnect and start up! Let it idle for a bit and listen carefully at the motor (IE: no radio or distractions) If I'm wrong which I don't think I am, someone will point me out If everything goes good from that point on, run some type of cleaner (IE: Seafoam, etc..) through the intake to clean the gunk out

    I hope you got luckier than I did. I ran through a lake of a puddle last week, sucked water up into the intake and when it hydrolocked it blew #7 rod out the side of the block and bottom of the pan

    I dont wanna step on anyones toes here but I dont think hydrolock is the problem here. He said the car is overheating and he is losing coolant. Hydrolock doesnt make coolant disapear. I think he has a popped headgasket or something like that. This could cause a hydrolock from coolant, so simply clearing the cylinders wont fix the problem.

    Thats whats leading us to think he may have hydrolocked the engine and caused internal damage.
