Is the hole in the intake a hole and I need to replace it, or is it missing something that goes there?

I was driving about 30 mph I heard a loud pop, and when I got home I popped the hood, and there was coolant all over the intake, and the motor. I noticed a small hole in the back of the intake. Is there suppose to be a hole there, or is that the loud popping noise I heard, because now my car will not hold any coolant!
Do you

Is it a plastic intake, is there coolant coming from that hole, and does the engine run?

In fact, there is a service bulletin and sebsequent recall that may apply. The recall was only good for 7 years from the vehicles warranty start date, which yours would be out of.

The bulletin info follows:

If there is coolant coming from the hole, then I would say that the intake needs replaced. If you are unsure, then a pressure test of the cooling system is recommended, to confirm.
