2011 E-tec blowing coolant out surge tank

I just got my sled back from the dealer after having an engine replaced due to piston failure. Now if I fill the coolant surge tank to the proper level, when you rev it up, it will shoot a stream of coolant out the vent hole a good 15 feet. I have to run the tank at a lower level now to prevent this, also it sems to be running at irratic temps. I have put 185 miles on it since I got it back and there has been no change. Any ideas?????????? Also I have tried two known good rad. caps.

If you leave it at the level it "wants" to be at(like after it pukes out the coolant) will it stay at that level or does it puke more coolant out all the time? I have found that engines set their own coolant level most of the time and not to fight that and I ignore the mark on the bottle and use it as a guide line for the first fill only.
