I installed a 2 quart overflow tank which works well. I had a smaller tank and it kept puking water coolant and it was always empty when the motor cooler. I thought maybe air was getting into the system, but the larger tank disproved that theory.
The outside temp was 43* degrees today when I went for my ride. It didn't go over 180* even without the fan on the entire 1 hour ride!
