Wait hold up.. just re-read your post..

"it goes straight to the ground"

Does that mean AS YOU POUR, it's going straight to the ground from underneath the car?? or after you run it for a while, it OVERFLOWS and shows up on the ground?

With the car cold, fill the tank to the "Max" line marking. Underneath the plastic "cover" under the two caps, lift the valve clip and go drive it for a bit (put the caps on). That should remove any air from the system.

Tank replacement is 800-900a dollars
That would be worst- case scenario.

And the coolant that should be used in these engines isn't green.. You are asking for corrosion issues.

T-stat or cooling fans. Could also be crap from the previous motor clogging the cooling lines, radiators, oil cooler - suspect engine installer flushed the lines thoroughly, but who knows.

From the sound of it, I'd suspect the fans. The coolant on the ground correlates to the overflow tube - designed to vent fluid if it overheats - which it would do with a fan failure.

Run AC and get out and check each side of the front bumper listening for the fans (2) running - with AC they should both be on. If not, suspect relays (there is a Hi and Lo) or the series resistor(s). Neither is a big fix.

Cheers!
