Run back out with a flashlight, take your intake duct off, open your throttlebody and shine your light inside your Upper Intake Manifold. Check for coolant inside. Get back to us.

I don't think I have ever heard of these engines sucking coolant through a head gasket. Not that I am saying it couldn't happen. But these UIM'* are prone to failure at the EGR inlet. Thusly sucking what you don't want it to suck. Coolant.

There has been issue where the UIM has cracked. regardless, you'll need to tear down the top end to see what happened. You should be able to avoid pulling the heads if it'* just UIM and or gaskets that cut loose.

Yep...the heads cracking on these motors is a true oddity. Let'* see what things look like when you get the upper end off.

I agree with Kevin.

Next time you see your car, pull the dipstick and check your oil. Look for a milky substance. You don't want oil and coolant mixed together. If you find it, have the mechanic drain your entire cooling system, and change the oil.

Like everyone else said, classic UIM failure. Mine went almost the same way  one horrible, misfiring one-mile drive across town, and then hydrolocked in the parking lot behind my old office.

Mechanic had to replace the plugs, wires (unrelated to the hydrolock but pretty shot), oil, coolant, and UIM. He told me that he had to dry out each cylinder by hand; the car must have been thirsty  the entire overflow tank and a good portion of the radiator were sucked dry.

If you get out of there and lose less than $800, then you have a very nice mechanic or more luck than I did.

I'll put money on the fact your EGR stove pipe is cracked. Change out the UIM and you should be set. Like said earlier, look in the throttle body for coolant right at the EGR hole
