I had dealt with this grief a year ago and it might sound stupid...
...is the coolant cap on securely?
Coolant will spill out of the overflow tube, but not from the cap...unless the cap isn't on properly. You may have to give it another 1/2 turn.
If it's not on tightly, the system doesn't have sufficient pressure...result: premature overheating!
Check that little detail first...switching collant brands shouldn't create this much havoc!
