[Cooling System Upgrade] 1-BAR Radiator Cap
this thread will document my experience in the trial of a 1-bar radiator cap for the cooling system on my e46. i will document coolant temperatures, any noticable benefits, any noticable differences, etc.
the cooling system is presurized to 2-bar from the factory from BMW. a 1-bar cooling system will theoretically provide more reliable cooling system performance.
i will update this thread periodically. for those of you that have any questions, you can PM me or post in the thread. i work a lot and travel frequently for business, but i will update this thread as often as i can.
