is 1 gal bmw coolant enough?
My 330 had orange coolant from the dealership, this may or may not have caused the upper hose to spring a leak. So i replaced the $50 upper hose... and purchased 2 gal of bmw coolant. Bled the **** outa the system by leaving the upper bleed off and topping off in the radiator fill till it came out clear, 6 total gal drained. I then emptied out the radiator and poured 1 gal of unmixed coolant in. It only took the 1 gal of coolant then maybe 1/8 of the distilled water i purchased. I live in MD where the lowest it gets is maybe 20F. Do you think ill be fine or should i drain the radiator again to add the 2nd gal of unmixed.
Im ticked i went out of my way to get the dam distilled water and 90% of the water is tap water after all. lesson learned i should have read more into the multiple drain plugs. At least we have good water here with low mineral content.
