Running Hot

I gotta call BS on some of this.
The radiator will fill it'self to the top even if you don't because of the return from the overflow tank will keep adding to it everytime it cools down.
And I doubt he's running warm and hasn't chked the coolant.
The rest is good.

Which part dont you agree with ?
Sounds as though you are talking about a "Closed Cooling System" with a recovery tank,which (I'm guessing) 9 out of 10 cars on this site "dont" have.Im assuming the OP does not have a CCS.
The proper way to fill a radiator without a CCS,is just above the top row of fins. The top portion of the radiator is for expansion.
