E46Fanatics - View Single Post - [Cooling System Upgrade] 1-BAR Radiator Cap

A 1 bar cap will lower the boiling point of the coolant by about 43º F if i'm doing the math right. That's a big jump. You may throw things out of the range of expected inputs from the ECT sensor and other elements and cause issues.

I'm in for results. But 1 bar seems much too drastic.
