There are a LOT of threads on this. Air head in the cooling system, you need to "burp" it..

Both my trucks have gurgled since brand new, I pay it no mind.
Coolant level is fine.
Seems to be worse after plugging in the block heater.

Mine does it as well, nothing to worry about.

As said, no problem. I got all the air I could out of mine and I found that a little "wetting agent" helped reduce it to the point I can't hear it at all. I used the stuff from NAPA.
