Bubbling in radiator water and loss of water suggests blown head gasket. How do I test which bank/cylinder is blown (3.8L Chev Lumina v6)?

You could pull the spark plugs and pressurize the cooling system to see which cylinders fill with coolant. I would tend to think that if one cylinder heads needed to come off, that the other might just as well come off to as insurance against having to do the job twice.

I don't know why it would matter. If the engine got hot enough to damage one side, there is likely damage to the other side too and it would be very foolish to only remove one head after going that far.

As usual, my fellow moderator has made an excellant point and I couldn't agree more.
