I posted this on another thread but posting it here for the record.

Today was the first real test with my new Bergs radiator. I drove up the grade on 421 towards Boone. This is a 4 1/2 mile 8% grade. The temperature today was in the high 70's. The car has a 160 degree thermostat that has been modified with 6 holes 1/4-inch in diameter in the flange. The temperature gauge is off of the outlet pipe at the top of the head. I am running 50/50 antifreeze/water.

This would have been a boilover event with the old radiator. The coolant temperature reached 180 degrees and the Motometer fluid reached about 1/3 of the way up. I was in 3rd gear with the pedal to the metal and the GPS at 48 mph.

There was a little outflow of the coolant but this is to be expected and I am not refilling the radiator. All in all I am very happy with the new radiator.
